All user reviews for the Peavey Rock Master Tube Preamp

Preamp lamps Peavey USA
4 loupiottes 12AX7 fired for the Sovtek, EH, etc.
size 19 "1U
3 channels: Clean / Crunch / Ultra
2 among high / low gain
3 mono outputs: XLR (line out), normal Jack and jack 10 db
1 crankset output (very cheap by the way) stereo jack
clean channel: 1 volume, 1 3-band EQ (passive) and presence
crunch and ultra share an active EQ (Voicing) and each have a gain and output volume, pull depending on gains to add a layer! EQ: Bottom (bass) Body (medium, pull function to use a different range of mediums) for acute and Edge).

5 Insert Effects (yes, 5 !!!) mono shame ...
one for clean and one for the crunch, one for the lead, one for crunch and lead, one for 3 channels!

USE

B'ah, as on any non-programmable preamp, turntable knobs playing up what it sounds.
The manual is very succinct, but, well, as everything is very simple, no need to panic.
The Dtail irritating and there is no LED to indicate it is o, y 'on the crankset that is indicated. It's a shame ...

SONORITS

The clean sound is honest, there is all the same very crystalline whatever rglages EQ, moreover quite effective.
The crunch is quite nice, hot. It is strictly the same grain as Lead, just a hair less gain.

Ultra, he is really bourr gain. The active EQ is very effective, hop! amortized on the bass that much smack, a big hollow in mdiums ... but still, a lot of sharp turn

Big potato, certainly, but used with a noise gate ... it'll really better.

NOTICE GLOBAL

I bought it new in 1993, sold in 2002 btement for peanuts ... A 2800 FF at the time, c'tait the cheapest pramps lamps, so I ru it, and enjoyed myself for quite of years.

Well, over time, b'en there's stuff missing: stro output, recording output, a switch in faade to change channels ...

A buy OCCAZ now for mtalleux djeunz looking fat saturation and grain inimitable lamps without a Elysen budget ... It is my opinion a better plan (RockMaster midiswitcher +) that a JMP1, for example ...

I do not regret having bought and used all this time!

Preamp has lamps (4 12AX7), 3 channels (clean, crunch and lead), incredible effects loop (1 for clean, 1 for the crunch, one for the lead, 1 for 2ch saturs and finally 1 Common has all channels). Prampli rack 19 ''. 2 outputs (a 1V and 3V for a power tube amp). What more ...

USE

For use is simple you plug the guitar is connected to a receiver behind and turn the knobs until we find 'the' sound ...
Namely it possesses an equalizer for the clean (volume, bass, mid, treble and presence), a Volume 2 lead channels (pre gain and post the pre gain knob has drawn for 1 maximum gain (gain sweater) and on each channel), a common active equalizer saturs the two channels (bottom, body with a knob pull it towards you to pull the shift (ie sound dug in the mids) and edge). One rule initially clear sound then passes the fun part in their obsession with the saturs channels ...

SONORITS

Then all depends what one desires but in principle has pretty much everything is feasible ... From pretty clear sound full of bass and treble or bloody medium in passnt by the little crunch and arriving at very very Wholesale full or hollow, mushy or own I know what he can not do. The sound produced is still relatively audible, as you wish, thanks to the many settings that can always meet and for only 1 knob to change and radically change the sound. The question is, is roughly what you want and we finally find happiness. Still, if we have enough in raproch but it does still have pa ca we slide a little 7 equalizer bands boss or Berhinger (cheap) and you're playing. Finally, the very important TIP: lamps ... I managed to flush out my Rockmaster on ebay and has an American when I received I try and I was super deu (and yeah I ' had also read other reviews) ... I opened the beast so for mine I was 3 groove tube (2 12AX7 and 1 12ax7R 7025) and an electro harmonix (12AX7 eh) I change the order in inserting an old loupiotte a marschall ei and I turns a 7025. And has the force of reverse and reverse the miracle is understood namely its filled with a huge gain with harmonics galore and very own

NOTICE GLOBAL

I did not for a long time, certainly, but I remain convinced that for that price I could have without looking better.
The sound is powerful and very clean but I plug a multi rack effect in the common effects loop but I have not been convinced ... hard to see ... But for 200 euros I do not do the choosy and gives him his little 18 simply because he deserves them ..

preamp has lights that visibly works to perfection with 12AX7 china ....

5 loop effects ca c is top:
one for each channel and a channel 2 for a saturated and finally to the common channel 3.

UTILIZATION

There is nothing that breaks three legs has a duck in the idea of ​​touring knob ....

the manual is sometimes useful for a used wisely well make the difference between 0V / 3V and XLR output.

if the lamps are effective on branch on buggers and ca sending 400gr steak like for enslaved person

SOUNDS

yes yes yes it has totally agree that I play with a very progressive game is just not doing more vintage XD

with this war machine I get the sound I was looking for since the dawn of time, for my part I do not use me 4 * 12 and other engl power ball I do not know what .... my preamp sound card xlr, guitar rigg April 1 pair of 4 * 12 reward with a sm Micro SD 57, a relatively short delay psycho like 450 ms and a touch of reverb back and BAS-TA!

nothing ca, it gives the same effect as a phalanx of cabinet space in the front less.

I play with an Ibanez vai a petrucci ibanez, a universe, esp m2 a brief of what beefy ...

when you take a little cabbage over the clear sound can dislocated casually always rigg 4EN downstream ....

OVERALL OPINION

Customers who bought this product on the net has already 1 year OCCAZ 200 m balls seller had certified that it functioned but nikel c arrival home was a disaster because he was stranded (without me having the say) following welds well done .... So 50 balls repair costs.

short all this back on the right path, I first tested the distortion 1 in pull mode and ...
I have been blown away by the grain and texture, I listened more than grain remembered "pull me under" I'm not saying I have it, but a very similar approach with the grain well "dug" this kind of super well-overdrive "right" good "narrow" good "own" that could be compared to that of Rondat or even malmsteen.

when we play in push mode, the grain is "wise" ideal for phrasing of intro "satrianesque" remaining volume c background is truly amazing

when do we go ultra fashionable c is the medium that expresses itself and the fury of a shred s can be expressed in the cleanliness and the velocity c is really a tool exception.

the clean is a little "vintage" but if it was a little fired pretty clear sound quite similar to the iced earth for example (it certainly must love) me I love this type of sound 90/2000 well-honed ear.

I can not understand: or else we found that it was "Criare" and "too sharp", is reviewing the amp just be or used otherwise for me frankly nothing to say.

I've used distos: metal muff, tubeman 2 ds1, ds 2, digitech death metal and other mt2 but I have found the gem that brings to m if its "narrow" and "right" I sublime in Rhythmic "pull me under"

Not having the funds to pay me a triaxxis, I folded my hope that in the above, and I am delighted with the quality of this product (which requires a little maintenance from the top of its 25 years .... )
peavey c is right, c is sharp and ca not drool, again you must love! (You find these little grains through VYPYR amps that are far more stunning than line6 pod xt for example)

I put 9 because

- Without the switch you have in your bones to change channels and to top it all it is a very plastoc switch in ugly ....
- Must stop play to play the "push-pull" that n is alas not the motorized switch :/

I toggle from time to time with my voodu valve (and the same preset rigg4) has an interesting grain but it is another story

if he drops me, I rechope in a presto on the net!

Lately, I've been reading where people are making claims that the Rockmaster preamp was the "inspiration" for the Peavey 5150 amplifier. It was not. I worked for Soldano back in the 1980's. Ed Van Halen came in and bought three SLO-100 heads. He took one and showed it to Peavey. That's where the inspiration for the 5150 came from. The preamp of a Soldano SLO-100 and the preamp of the 5150 are identical. I remember Mike Soldano being a little miffed about it at the time. Eddie also took the Music Man guitar they made for him and showed that to Peavey, too. This is where the Wolfgang came from. Sterling Ball was not too happy about that, either. A person who I considered a good friend took one of my own amplifiers that I had built for him that contained a unique overdrive circuit and showed it to Fender. Later, a few of Fender's amps implemented that same overdrive circuit. Coincidence? I think not. In any case, the Rockmaster preamp has nothing to do with the 5150, no matter how badly you wish it did.

UTILIZATION

It's OK.

SOUNDS

Average.

OVERALL OPINION

It was cheap.

4 12AX7 preamp lamps,

One for the clean channel
1 for the "crunch"
1 for the "lead"
1 for equalization

Rich connectivity, an effects loop for each channel, one for saturated two channels and one for 3 channels.

Possibility of wide sounds fine equalization ... too?

UTILIZATION

This preamp is relatively simple to set up, take into account the push-pull of voicing (body) and pre gain mistletoe act as low-pass filters.

The sound is very metal, death rather 80's 90's

I've never seen so much gain on a preamp, beyond the 5/10 is also difficult to use.


Essential guide

SOUNDS

This preamp is built for shred, metal and possibly a rock a little stonner. It quickly gets a heavy sound, the first kind of Megadeth albums.

The clean sound is bright enough, lots of bass.

OVERALL OPINION

Good product for the price, it brings a strangely mesa boogie studio preamp, and by design, and share these components ...

Very good choice for the above-named styles.

Prampli lights (4 * 12AX7) three channel (clean, crunch, ultra).
legalization for passive and active clean for both leads.
Between high and low gain, the rear connector complre, especially for the effects loop.

UTILIZATION

Simple, turn the knobs, you push the gain and it sculpts his sound quickly.

SOUNDS

This time it's a pramp for rock and nothing else.
I tried it with a Peavey 50/50 power amp.
The clean channel is not bad, except that with humbuckers the crunch quickly, so you have to play with the gain low (<4) or with simple microphones.
The crunch and ultra are similar, with a bit more gain on the Ultra.
The saturations are good, especially if you pull the knob towards you gain (+ gain even "pull gain").
The legalization is effective, with a pull to shift mediums, there is a wide range of sounds.
But the sounds are generally quite mediums, to have a dig its trs must activate the pull shift, lower mids -9 -12 or while pushing the bass and Aiges. Be careful even above 9, the low cause a "quagmire" dsagrable, and treble screaming deviennet trs

OVERALL OPINION

In the end this little prampli is nice: trs reasonable weight, simplicity of use, many possibilities To insert effects loop, but in the clear sound could be better, and the saturated mdiums has too much, and then gain a level not enough to balance me, voodu valve is better for it.
Nanmoins to make hard or mtal simple with good sound and without taking the head is a good investment trs

Then the RockMaster is a all-tube preamp, but not MIDI, 3 channels, clean, crunch and lead with an effects loop for each channel, a general loop, 2 outputs and preamp preamp output level microphones.
This preamp uses 4 lamps, 3 for channels 1 and for the effects loop.

UTILIZATION

Good use is not complicated you play a turn knobs to make his sound but the settings may seem subtle, especially in the lead.

SOUNDS

I play metal and let's be honest, I do quasimment the lead channel on my amp classic al 50/50.
This preamp has a particular grain and fat enough Loading High mediums quite runny.
on the other hand I opened my preamp (bought used) and I understood everything, the four lamps are lamps peavey stamps and identical, so nothing folichon.
so I will Retube almpes with better quality and adapted for each channel.
APRS Retubing I repost an opinion.
on the other hand in the lead channel preamp has a good amount of gain that I find sufficient for the metal.
APRS see a retubing.

UPDATE OF 03/05/04
well I changed the lamps in the beast, I have kept the lamp there was for the effects loop, no great interest to change it.
if not in light of I put a Electro Harmonix 12AX7 and two lamps saturation I put 2 Golden Dragon 12AX7.
good conclusion, perois a slight gain more and more golden dragon load the sound medium.
but in the end the sound is more precise and cons I find that said gain of said hair blowing in addition but it's not very hard to solve.
Voil

OVERALL OPINION

A good preamp for the price at which it can be found in time, again without a problem

Guitar Preamp with 4 12AX7
A clear channel, a crunch, a lead

UTILIZATION

Warning: without the footswitch you can not change channels ... in this case the preamp gets stuck on the lead channel!

SOUNDS

Peavey Sound type: Brilliant with a good medium heat in the lower plain, in the saturated aggressive but prcis aig, inflated harmonics and powerful ...

Versatile lamps offer a wide dynamic mdiator sensitive to attacks.

OVERALL OPINION

It's an old pramp I bought used in July 2004.
He suffers because of its technology to an S / N lev particulirement pretty well saturated on-channel!
But the quality of its grain supply and remain even when trs charmers.

Tube preamp guitar (4 * 12AX7, in general these days we only have 2),
-Entry low and high gain,
3 channels:
Light with spare + prsence equalization,
-Crunch and distortion equalization with common gain and channel volume, push / pull to increase the gain on each channel.
5 Boulc effect!
Clear-channel
-General
+ Disto-crunch
Single-crunch
Disto-only
3 outputs:
- 1V to connect between the return of the effects loop of a head
- 3V to feed a power amp tube
- Balanced XLR DI out
footswitch essential if we are on the channel distortion all the time.

UTILIZATION

Use mega simple, you plug it and turn the volume knob>>> the sound comes out
The equalization is passive but active clear sound on the sound was saturated and the margin!
Note, a push-pull on the medium that moves the frquence that one rule, to have a sound a little hollow or contraite settle more in the upper medium.
The manual available on the peavey site provides examples of settings that I did not test but anyway it's hard to make it sound so bad its use is simple ...

SOUNDS

It's really a good camera! The clean sound a bit saturated with powerful microphones if plugs into the high gain, low blow I use the boost gain + gain on the Distortion channel.
The sound and really Clais lens, a layer will do wonders in it,
The crunch has a range of its super Varis, clear of the large distortion if you push the gain a bottom and passing through beautiful bluesy overdrive and crunch rock with biting well even when a modern touch, not too marshall, ca change for once!
The distortion channel has gain a reserve Whereas, if you start in high gain you will not need to put a background for the death metal distos crazy! The grain is very tight today.

This preamp really respond diffrent depending on what you plug in, an SG team in EMG in channel 3 you block out sound massive and compact that will make your walls vibrate, a Schecter Drops Si a shot of a little less attack and a DIFFERENT microphones will sound just as huge but diffrent that the microphones are less acute in charge.
In the crunch channel, a layer will give you a beautiful overdrive as I had always rev before, if he is my les paul a apresn without changing the settings of the ca is good rock'n'roll crunch

Huge advantage of this machine, for my case no breath! I believe it! No one pete background noise with humbuckers!
I put 9 because the grain can put off some modern some fans and I think with a good set can be about anything you want but not really all in the strict sense of the word.

OVERALL OPINION

I have a few days, but I have absolutely no complaints, the gain has a background to LARSEN trends but it is reasonable and normal.
I wanted a 3-channel preamp tube with a real clear, I'm ready!
The pink and blue well srigraphie eighties gives a priori on the beast and we should be wary! This prampli very close to 5150 t and the base of the head pramp peavey XXL too.
On occasion it is found in the 200 euros and for that price there is not much else to another, as I have no money to throw in a TriAxis I think hang on to this beast.
The grain a little modern disposal may be few but me I was tired of Mr. Marshall's everyone and I found a shoe my foot!

Preamp tube, four 12AX7. Triodes assigned to the input, to clean, the Satus and even has the effects loop.
3 Canneaux Clean / Crunch / Ultra with a boost for both saturated and a cranberry EQ Separée clean and Crunch / Lead.
Active EQ on cranberry saturated (-15 to +15 dB), Meidum button push / pull to change the frequency applied (Truva and a big big sound!)

Loop effects of death for all 1, for a clean, one for crunch, one for the Ultra 1 and Ultra for all / Crunch. Config monstrously Complete!

1 V output for power amps, pedals, etc., 3 V for a lamp power amplifiers and line output XLR for direct input in a console.

Stereo footswitch jack, internal power supply (hopefully!)

Model Rack 1U solid.

UTILIZATION

Configuration very simple and very fine adjustments. Tinkering in the active EQ, you can change the sound a lot by moving the little knob. Think noted its settings

The manual is adequate, the inputs and outputs are well detailed. After it was our brains to play, nobody can find our sound is our place

SOUNDS

Retube preamp with phillips (dynamic and beautiful grain, soft saturation)

Peavey Grain is here ... But what a sound!
The Clean may be slamming or jazzy, very dynamic.
The Crunch can tickle the channel lead to a lot of other preamps. well balanced, it is comptueux. A beautiful grain.
The Ultra channel is monstrous, very powerful, super compressed, close-grained and compact for its very heavy but precise.

In short, Jazz / Blues / Rock / Heavey-neo-death metal, anything is possible with this preamp.

OVERALL OPINION

It is incredible!
Anything is possible with this preamp.
In home studio through a simulation of speakers (even an ultra imple-G or v-amp which disables the preamp) give enough gain for all bourrinos and enough personality and drive to all the blues.
Live, he will gain too much to give, and the Crunch could be enough to play Mr. Manson.

Preamp perfect, versatile, with a beautiful timbre and Clean / Crunch hyper dynamic.

Is not very expensive OCCAZ (currently about € 200), so the value for money is extreme.

EDIT 21.08.2006:

I went for the simulation of baffles v-amp 2 has a microcab. I have also been heard as true, this preamp is always wonderful, but even more than before, if possible. I rediscovered the grain and the intense heat of crunch.
Also, I replaced the lamp V1 input stage by a lamp with a beefier and to gain supperior Phillips: The grain magic is still there and the change of a single lamp has really increased dramatically gain. This preamp has its own personality but they also respond very well to changing lamps. A true wonder!

What type of amplification

A lamp of course, four to be exact.
In a clean
In a Crunch
An Ultra
And one for effects loop
What connections

2 Came a High Gain and Low Gain (I use only High personal since I play metal. I'll make an update with more details on the Low Gain)
Output 2 1 / 4 one has a 0dB and 10 (which was 10 when I did not have my power amp it Grisha. A review in the update)
Balancer has an XLR-10db
5 loop effects. For a Clean, Crunch Ultra, Crunch / Ultra and all these reponce: P
What are the settings, the effects
Very precise adjustment. Especially for the pot Edge saturated it is very very sensitive. a bit too and it's a bit too Criar and not enough is too dull. But after long seconds, there is a very good sound ..... loll

UTILIZATION

Setup is simple-it

Ultra simple, we can easily have a good sound. I put about a 10 minutes at the start to find the base and then during a practice he and some editing done.

Do you get a good sound easily

Already answered just up

The manual is clear and sufficient

Yes, it gives a few mm settings but I prefer mine, and the rest of the gear (power, speaker, guitar, and especially guiteux) bcp change the sound.

SOUNDS

Right for your style of music

Well, I play metal style Children Of Bodom, my config is the first shoot Crunch with a 8 and a post 10, the EQ is a 0 Bottom Mid shoot a 15 (yes jaime the mids. . .. lol but with my Bill Lawrence L-500XL sound is precise cutting with a knife. I'll add a bit of pe bottom) and the Hedge between 0 and 3

With what (s) guitar (s) / low (s) or effect (s) do you play

Guitar is a Jackson Kelly with a Bill Lawrence L-500XL bridge and neck nothing
Plug into a VHT 2/50/2 power amp and EL34 mount a Marshall 1960 Lead Bafle

What kind of sound you get and with what settings ("crystalline", "bold ",....)
I explain one of my setting, but I also have a suc has the Dimebag Darrell (with a can of mid)
The config is on channel Ultra Deep and gain benefit.
The EQ bottom between 6 and 9, about a mid push and -3 (mm push on for up to -6 to be faithful to Darrell) and the Hedge between 3 and 6 (can not go higher PCQ vrm as I have said the sharp .... vrm acute)

What are the sounds you prefer, you hate

I find the Clean asser disastrous, with a gain pickups jig is the cat, but I'm not a user clean so its not mind vrm
I would compare it to the PCQ and see if I Tubefex to couple the two (the distortion of the rock with the effect of clean and TubeFex)
I put 10 clean since I do not feel so pe vrm found a good config
Jadore the sound saturation.

OVERALL OPINION

How long have you use it?
About 6 months, but with the power and cabs 2 weeks

What is so special that you love the most, the least

Clean the monk and that its Hedge setter bcp too high
Most everything else

- Have you tried many other models before buying

Yes, but when you want to gain peavey, peavey only can you make it ....

How would you rate the quality / price

For $ 330 (Canadian) shipping included is wonderful.

With experience, you do again this choice?

I want to see the TubeFex of Satu, if the mm is more unpreamp conplet his side, but Jachet mm if I keep the Tubefex RockMaster, VRM is all I wanted.
PS.Je will not change the lights in a long time, I want a meter and a ground-Tung GT ('ll assume the Chinese lamp rings mieu RockMaster the dns.) Electro Harmonix and probably the Clean (which is currently on the ultra)
I gives news.
Issue for comment, setting or advice do not hesitate

2.5-channel preamp tubes (4 tubes, which combine to create different levels of gain).

Many loops on the rear of the animal (but it is better to put a strap if you use them), and a footswitch to change channels (can not switch between channels without)

UTILIZATION

Nothing complicated, turn buttons, pulling on some buttons (push / pull for gain on the crunch and ultra channels or mediums to dig) .. It could not be easier!

A small problem, common to the equalization crunch and ultra channels. So we must make a compromise between the soloist and the rhythm and see the Lead as a booster for his solos rather than a separate channel.

SOUNDS

While there, it sends heavy! (Tested with lamps peavey original).

The crunch and lead channels have a huge headroom (there are too many, I never exceeded the 5 or 6 of 12). It sounds very like peavey saturation (cold, dry, and a little fuzzy), very close to 5150. In his lead, we arrive at a sound approach to the EVH without any worries with a scraper to humbuckers.

Be careful to have good microphones, microphones imprecise tend to drool and give a slurry foul.

I just find the treble a little too aggressive on this preamp, but it's still a good machine!

in clean, fine, I would say no more. This is a clear American style, very straight. I would say it's interesting for a metal.

OVERALL OPINION

I have this amp for 2 months. I bought it to complement my JMP1 to make me a versatile rack (JMP1 = big rock, RockMaster = metal), and it fulfills its role!

Attention, however, it is not a very versatile preamp, but it remains a very good unit, very rare and hard to find (again, with its qualities, it tends to sell readily used).

I had mine in perfect condition, hibernating in a homestudio for over 10 years.

O Here is a site we have changed the bte but do not rely on sound poorly recorded.
http://www.fjamods.com/Rockmaster.html

UTILIZATION

...

SOUNDS

It's full of lights (there is no one but 4) and means.
Proof:
https://i201.photobucket.com/albums/aa147/tubeguitaramps/peavey/PeaveyRockmaster.jpg
3 channels:
The clean sounds can be crystalline, Mark Knopfler Hello friends
It's hot. It is his lamp.
Crunch or saturation of high quality.
His hyper saturated death metal genre possible.

OVERALL OPINION

Can easily compete with the high-end preamps lamp.

Ladies Gentlemen: This is a REAL full preamp tubes (which is rare in the racks) and it's a MONSTER! Three channels: clean / OD / distortion with EQ 4-band EQ on the clean & 3-band common to the OD & distortion. 4 effects loops: one per channel + a global practice to insert a delay on its lead by example. Note: one of the four lamps RockMaster is used for loops (to enhance the signal at the output of the pedals).

UTILIZATION

While there is clearly the plug and play: This preamp sounds regardless of the settings, unlike some preamps that must be addressed to the millimeter to have a drinking her. The RockMaster plugs is adjusted in seconds and the eq ... graaaaaaave it sounds! On any gear, even live on a sound card as it does not simu HP! (Lower acute need of course)

SOUNDS

The sound is clearly the biggest asset of this preamp: it rings, it rings and rings! It's amazing: the sound is not round but rather "right" with a lot of heat, however (not dry, attention), which surprised me at first use is the clean bass, very present , which give the appearance that I might call a little "dark". Do not hesitate to put a lot of mediums.

There is also a push / pull mids on the eq OD / distortion that can dig the low-mids, this produces a modern sound (useful for the hardcore, yeah!) Highlighting the low very serious. I use a 10 band eq pedal between the preamp and my power amp to select the frequencies that I like, and there is obtained almost sounds pro.

OVERALL OPINION

YES, I would do this choice, this preamp is amazing, every time I play as a group the guys laughing on seeing the vehicle whose design is a bit dated (pink & black!) But huge eyes open when I myself to play! This preamp has only three sounds, but of excellent quality. I got mine at € 200 ... he ridicules or any distortion pedal and a lot more amp Honer. Food for thought ... <img class="smiley" src="https://fr.audiofanzine.com/images/audiofanzine/interface/smileys/icon_wink.gif" alt="wink" />

This is a great sounding and easy to use preamp. Th features and easy of use coincide with the quality that Peavey stands for. Peavey has made some amazing sounding pieces of equipment this is one of those legendary units that still has a great place in today's modern music world. If you want somthing that is cheap but bot cheaply made and that will sound fantastic then this is a great preamp to start with.

This unit has been rumored to have been where Peavey got there inspiration to do the 5150 amps. Most people who have been around guitar amps enough know that the Peavey 5150 amps that were a signature model for Eddie Van Halen have been one of the most used and highly sought after not only for their sound but also for their competitive pricing. I have seen 5150's go for the used price of $450 and as high as %900 depending the conditions and what not.

UTILIZATION

This unit is essentially a three amp preamp which has a clean gain, and crunch gain, and an ultra gain. These modes or channels all share the same EQing and equally have a place to stand on. Each mode has a great sound and fits into a set list quite well.

There isn't much to get discouraged from or misunderstand with this preamp. The controls are laid out very well and easy to understand. The definitions of each control knob are pretty self explanatory and easy to figure out. The only thing that is unique is probably the post gain which is essentially the volume for the amp.

SOUNDS

The tone from this amp is phenomenal. I think the Peavey tone lives on the ultra high gain mode whether it is a 6505, 5150 or this Rock master. The ultra high gain modes in most of not all Peavey amps sounds the best to my ears. I ave ever been a fan of their low gain amps such as the classic series or simply just the clean channels of most of their amps. The uber high intensity is the Peavey tone and most likely will be for ever amp they produce.

OVERALL OPINION

These units have been discontinued a long time ago. So the used market is the only way to go to grab this unit. I have seen them for around under $200. That is a great price for this unit. The only competitor for this preamp in my opinion is the ADA MP1 which is another phenomenal preamp. Different voicing but a beats on its own as well. This preamp is a little cheaper than an MP1 , but the ADA has more features.
