rakoto's review "Efficient and reliable"

All-tube 2U power amp (eight El 84, two 12AX7 and one 12AT7)
2x 50 W output power
Contour and presence controls per channel, very musical, ideal to adapt to the acoustics of a venue.
Comprehensive connection options (DI output to use the amp sound in studio, for example, slave outputs to use a second power amp, several impedance options, possibility to switch to 100W mono mode for a 4x10 stack, for example).


It's intuitive, so it's very easy to use.


Very British sound, similar to a Vox power amp, due to the El84s. However, it respects the sound of the preamp. The best sound I have ever gotten was with a Mesa Boogie V twin as preamp. It delivers a very creamy sound.


I've been using it for four years. I previously had a 3U 2x60 model, but it was too big.. It worked very well with my Triaxis back then. A similar sound to a Mesa Fifty:Fifty but with much less dynamics (and less expensive, too)
Unbeatable value for money...Ideally coupled with a Mesa.
The fan is a small drawback, it's annoying in a small room, but imperceptible onstage.

James...'s review "Warm and transparent tube power amp"

For those of you guitarist who use rack stuff (you know who you are) you also know how discerning out tastes our. Not just in rack power amps but for every facet of our rack hogging reality. Usually the only thing holding down the expansion of our racks is weight and cost.

For those of use who can't afford a VHT or a Mesa there aren't many options. But the Peavey 50/50 is one of those options. It's a 2 channel 50 watts per side EL84 power amp. Simple enough? Ok.


There's not much to this thing really. I mean it's a power amp. It goes in the rack. I've never had any trouble with mine. People say tubes aren't as reliable as solid state? I've had more SS power amps go out on me than anything and this bad boy gave me 5 years of solid use with no hiccups. In terms of tube gear one of the most reliable items I've ever had considering the abuse it took. I really have abused my 50/50 to a lot of shock damage but it's stayed well enough okay. I still have it to prove so. The only feature on it I don't like is the tone controls. Why do I need these? Isn't that what I have a preamp for? Whatever...I just leave them at noon.


A lot of tube power amps impart their own tone to the sound. Mesa's are warm and sort of Fendery. VHT power amps are tight and bright. Marshall ones sound like...well Marshalls. The 50/50 I expected so sound a bit voxey perhaps. Well, not so. It's got a really flat and warm response to it. It basically takes whatever preamp I throw at it and makes it warmer and gives it tube sag. This is really good for a guy like me who uses different preamps. I used to use a Mesa 50/50 and it never sounded right with Marshall style preamps. The Peavey sounds nice on everything really. It's not overly voiced to the tone of the EL84s. I found switching tube brands didn't have a huge effect on tone, backing up my theory. I really liked using this with my Egnater M4 and Axe-fx because it's quite transparent. Doesn't color the sound of those various preamp sounds.


If you want a power amp to emulate a tube guitar head section, this isn't your guy. If transparent uncolored tube warmth is the goal, the 50/50 might just be the ticket. I really mean that. For the value this is a great buy. Yeah, I like the more exotic and expensive power amps for some applications, but this is great especially when I'm on tour and I don't wanna risk destroying my VHT. It's easy to find these used for cheap. So go ahead and try one.

MGR/Gregg Orange's review "Peavey Classic 50"

Basic rock and roll, 70's stuff, old school punk, some blues. As long as it has a good rhythmic backbone. I have several guitars, amps, been playing for about 25 years, guitar and bass. Run a sideline guitar repair business out of my shop at home. Have owned and tinkered with a multitude of different amps, guitars, basses, etc. I look at Musician's Friend catalogues as if they were Guitar Porno magazines! Haw, haw! No, seriously I am 45 years old and it's a big part of my life.

I bought it off Ebay for around 400 smackeroonies!

I have owned a lot of Peavey stuff over the years and I have been most impressed with their PA gear, I always thought that it was a good bang for the buck. Unfortunately, I have had some bad experiences with their guitar amps and most of the ones I have heard and owned just didn't really seem to measure up soundwise or qualitywise. I always went back to Marshall, Hiwatt, Orange, Mesa, etc. I bought this one with the attitude that I would give them another chance because the class A design, smalltop-retro-tweed-quasi- mini-Marshall type head cabinet design looked promising, especially with the chickenhead knobs. I remember when I first pulled it out of the shipping box and set it on top of a 4x12 cabinet and plugged my Les Paul into it. After allowing it to warm up a couple of minutes and started fooling with it I just fell in love with the thing. Very versatile amp with not only great clean tones but also a great hard rock sounding growl to it as well. Has clean and lead inputs with a toggle switch to choose between the two. The 4-EL84 3- 12AX7 class A design sounds like no other Peavey guitar amp I have ever heard, it is really warm and natural sounding. This is like a boutique amplifier for a fraction of the price. Absolutely the best bargain on a used amp I have ever made. Most of the Peavey amps I have played thru in the past always seemed to have a really artificial, raspy and buzzy sounding distortion, not this one. In my opinion it is/was the best guitar amp that Peavey has ever made, and that includes the 5150, the Ultra Plus, the Windsor, etc. I recently was told that they have discontinues making just the head and now this amp is available in only combo form. Pity. I would buy two more at that price right now if I could find them.

The cooling fan is a little loud but, I will put up with it for the benefit of keeping the unit cooled down and operationally sound for that many more years. I honestly can't really say anything else negative about it. Peavey kept it simple and got it right this time!

Looks good to me, I have of course seen amps that are built like tanks by comparison but, I don't think I would have a problem taking it to gigs or out on the road at all. I'd probably put it in a roadcase to to be on the safe side.

Best bang for the buck of ANY tube guitar head I have ever purchased and that's no lie. You could easily spend 4 or 5 times what I gave for this head and not have an amp that sounds near this good. Trust me!

MGR/Anonymous's review "Peavey Classic 50"

I got this amp about 10 years ago in Saskatoon Saskatchewan Canada for $1200 Canadian.

This amp has tremendous flexibility. It can do honking and wailing rock and roll with the best of them, and it has the headroom and power to blast out clean country licks into a large room. The footswitch selectable channel control gives instant control over drive and clarity.

As with any all tube circuit, the player can modulate the sensitivity of the overdrive with touch control or with the guitar volume. This adds to the control of the overdrive.

Tone controls are useable and simple with a realistic and wide range of sounds available. The unit even looks cool. By removing the "Peavey" logo (2 screws) it cannot be distinguished from a vintage tweed twin reverb from 10 feet.

On top of all this, the long spring reverb tank is wonderful and not "springy" like the
shorter spring units usually found on smaller amps.

The 75 pound weight make it a chore to lug about I recommend adding swivel casters if you are going to be using it on the road. The Ernie Ball units fit well.

Solid and trouble free. I have yet to have a single problem in 10 years of use.

An excellent value. The price has since come down on these, and there is an effects loop built in. I would buy another in a heartbeat if mine ever was stolen.

An excellent all round "do everything" amp. It has all the power I need and the flexibility I could not do without. I plan eventually to get a smaller version of the same series (25 watts or so) for when I don't want to haul the big box, but still need good sound.

MGR/Anonymous's review "Peavey Classic 50"

Jay's Music Augusta, Georgia $500

I now have 2 Peavey Classic 50s, the head and the 212
combo. I have compared this amp to many others and it is simply better! You
can't beat it for the money. The controls are very straight forward. Dialing
in a desired tone only takes seconds.

There's very little I don't like. I wish it had a
seperate EQ for both channels. That would give more flexability.

All tube 3-12AX7 4-EL84, spring reverb,
two channels, one EQ, master volume,
presence, series effects loop, 3/4" cabinet
very sturday

I bought the head later and a 5150 4x12 cabinet to go
with it! Enough said.
Best amp out there for the money.

dj maboul's review (This content has been automatically translated from French) " I adore"

any lamp with lamps Electroharmonix it is very clear I think, especially in 16 ohm ..... really too powerful because it can connect 4 4 * 12 cab and it's really crazy ....... I have it ....... relamper brand in JJ for power and sovteck more 12AX7 and 12AT7 and the sound is no longer the same between his big muscles and greasy metal with many meduim ...... . the top for me


the configue n is not simple force of a meter crankset or preamp worthy, I have the is no manual occasion, I put 6 months to find my sound aprse but this time it is a pleasure


I play rock metal trash see any style, and I have tjrs find a way to create a crystal clear or bold because this amp is resortir the character of the guitar used, for my part I play gibson sg special equip DiMarzio and ga rich equip DiMarzio, yes I know these mics on a t stranding me jtrouve deemed not short with a boss gt6 ca ca hard and also the fineness


I have used the six years I was the accheter of a secondhand relamper I made a good deal a300euros head with such power, ps esiter not to use that one channel is also stereo as lol, with time I do it again the same choice but to leave it in a room where dry because I think the fragile beast and she does not like the transportation with time

Eulfred's review (This content has been automatically translated from French)

This is a very good power amp 2 x 50w lamps dlivrant, power is the I defies anyone to stand in front of my 4x12 less than 10 meters with knobs 5!

- 4 power tubes
- 4 lamps Pramper

2 volumes, 2 standby, 2 presence, 2 rsonance (low)

Both presence and rglages rsonance are very convenient because they can adapt the sound gnral bass / treble function room without reparamtrer its entire Pramper.


I use a Rocktron Piranha coupled to a multi effect rack Boss GX700, all in a 4x12 Peavey and send STRID.


This amp is rput "a little soft", certainly compared to some heads All tube amps more rcentes it will be worth a bit in terms of dynamics, but at current secondhand prices remain REFERENCES sre a solid and not CHRE, especially as a systm rack allows you to evolve in his config time, therefore, to add a Pramper "patator" type Engl, Peavey, Randall, etc. ... it has the advantage of being very "musical" and ragis very well in high-volume sounds bluesy.


This is perfect Poweramp all styles rock to metal, provided they add a very powerful Pramper in the latter case (and the guitar is going well too), his favorite fields s 'behind the blues / rock to hard 90'.

The pros: powerful, cheap, precise and musical, made to last

The -: noisy fan, a bit "soft" compared to current REFERENCES (who rate twice ...), quite heavy.

buckR60's review (This content has been automatically translated from French)

2 U rack amp lamps, 2 x 12AT7, 2 x 12AX7, 8 x 84 EL.
Electronic panzer is not the gadget is made to last.
Complte trs connector, Stereo or mono table, it adapts to all!


Be careful when making connections to impdances.
The rest is basic and effective!


Equip it with Sovtek rpond well on all frequencies.
He has a good dynamic.
The rising power is linear.
Guitar-di Marzio, roctron Voodou 2x12 V30 and an enclosure, to play rock and hard rock, and although it sounds!


Bought used 6 months ago, it is part of the hardware we are glad.
I just tried a Marshall EL34 50 (too heavy) and a engl rack (too expensive)
For it is an exellent 400 qualitprix report, even if it is not old, I think it can turn a few more years! Especially after a RVision in VHM!
If I do it again this choice? Msieur YES!

brui2fon's review (This content has been automatically translated from French)

See previous opinions
I just said:
connectivity offered is one of the most comprehensive
* Switch 4, 8, 16 ohms for each channel independent
* Mono bridge mode 2, 4, 8 ohms
* 2 HP per channel (four speakers can connect at all ...!

adjusting volume, resonance (bass), presence (acute) for each channel

lamps piussance EL84 (x8) drivées a 12AX7 (x2) and out of step uen 12AT7 (x2)


Very simple, pay attention to, however INPED


Ampl This EL84 is equipped with lamps
their particularity is very little color the sound
So this amp meets the grain of your preamp
So with a pod or JMP1, it will lack character
by against a Mesa or other mind-blowing it (tested and approved with my friends)
In fact, it colors the sound but very little heat and provides dynamic

So, he can marry happily with any material


The réaputation this preamp is more to do
its availabilty in opportunity and affordable price make it a reference

I use it with a personal Digitech RP-7 in Pramp to make Mtal no style, and occasionally rock. Before buying it, I played three months with the RP-7 branch on a fender, I must say that my sound has changed DRAMATICALLY. This amp is really excellent, both in terms of the power it is capable of dlivrer (never played in del 4/10, even in concert without being resumed, and yet I have a drummer knocking; o)) than the efficiency of rglages of subtle presence and resonance.


Trsrgulire use for 2 years and a half, no worries it.
The diffrentes possiblits switch to mono / st, of Impedance, output etc .. and connectors are really very compltes.

On mine, the fan made a little noise, it's true, but you soon forget ds when you start playing (unless playing 0.5 / 10, p ...).

Pay 5000FF there are more than 2 years: report qualitprix: UNBEATABLE.

/ *** Edit *** /
I played a long time stro and qq months (p ten) in mono, with big problems to happen. The guy VHM in whom I harbor seemed to say c'tait not the first time he saw a return 50/50 used in bridge, a cause of problems on the high voltage. Apparently the mono mode, it's not the config Idale for the viability of the amp. I test it tonight (in stro until the end of time; o)), and I will post in the coming weeks if it turns out that it continues to blow and that has nothing to do with mono.
