NOTICE GLOBAL

I, unwanted for 2 ans.Avant I Fender, the twin red knob.

100w amp head two channels. 4 EQ bands common to both channels. Independent reverb settings. loop switch effect pentode, triode or 50 / 100w. a little less headroom and harmonic 50. 3 12AX7 pre-amp and 4 EL34 power 2 for me as it was in Retube 50w .. SEE my opinion on JCM900 Dual Reverb 4100 (yes it is listed two Once the head ...)

I did Retube in 50w. Mine is equipped with EL34 and not 5881 (I think this is a very important detail.), Model lamp more représentaif sound marshall.

My lights are Mullard EL34 with a 12AX7 input golden dragon. (A must for the clear.) The powers are no longer as the number 2 course, 50w forces, so it's switchable 50 / 25W.



USE

I precisely this point in detail "sounds".

It is not so obvious as it seems ....

SOUNDS

The whole problem. its use does not ultimately proves to be so easy because it asked to be pampered Marshall future.

This is a maligned amp. For me, the views of a minority opinions "international", see eg Harmony Central.

This is an amp that ultimately needs to be tamed. The one does not ring on. Its major problem is its lack of bass. Its equalization which seems inneficace but gentlemen: Let's stay serious when he spits his bowels, CA has absolutely nothing to do.
And until now, I said loud and clear:
No amp seduces me as much as that one. I saw the green and not ripe for 10 years now ...

A highlight is the mode of operation of the lamps. In pentode or triode if I'm not mistaken. Or 50 / 25W.

25 it will tend to be more "soft" more chubby than 50 or it will sometimes be more acidic and sharp.

My opinion is especially the 25w mode.
The Channel A:

His clear and overdrive. Jmp sound can easily get out of this thing to be done: a small das GE7 the loop. A low one is there.
At higher volumes it will touch équalo the amp itself, las low wake, acute too! My setting is a low background and a support adapted to each situation by GE7. The mids and treble thoroughly virtually cut off. I play with the presence that makes the finest eq setting.

For the top, this is my solo trip, AC / DC and others just to rant a little amp.
For purely sounds clear I am quite a fan of the compressor mixture / chorus, which gives all its density. I use an old compressor Guyatone ps103 (mod germanium) cruised to a Boss DC2. (Never heard of such a chorus: MAGISTRAL).

Channel B:
Clearly lead! for the pun ... CLAIR lead-ing ... Ok I spell ....

It spits fire god! High gain, it certainly is not, but remember that we are coming out of a period or to saturate the amp that was all thoroughly developed bar ... and may be not necessarily the way to a pedal od significantly less accessible today.
Today, with modern music, the high gain mention seems ridiculous ...

The grain has narrowed, compact, mute already very nice .. Iron maiden, metallica and justice for all ... In her I always use my GE7, but in addition I stick him overdrive on the teeth!
A sd1 or Od1 home boss, that's what makes it sound better, mediums forward and dry acute, are perfectly acitivities grain of the amp.
Mutes are so daunting! mdrr!

One enters the Deftones without worry. It's heavy, dense and thick has wish. Muscle Marshall in all its glory, every time in 3 years I remain stuck and I'm in love! It amazes me to this amp AC, he knows how to clean, hard, heavy metal and carefree.

The reverb filled his role well, I find it a bit long, fine adjustments to the beginning of beach ca not displease me ...

In short, a versatile amp with a vintage anyway its always on the settings of channel A, and well suited to rock / hard / heavy.


NOTICE GLOBAL

If it were to do again, (I got it for 400 euros) I remade on.

In short it is an amp you need to know and do to tame what he's done. Versatile, and also inexpensive opportunity. For a review and a max!
Some settings and for me (it's also a pleasure to be HIS type of sound) in 25w rather, good lights, good effects and good guitarist.

Finally I ca work! mdrrr

All t said.
the loop is very useful (not work very well as on many amp made in china!)
switch hi / low super efficient
power tubes el 34 or 5881 (6L6) as model (I have a 6L6 and EL34, so I speak both)

USE

Super easy to use, sounds are easily exploitable, just make sure the master volume aprivoiser very reactive but even low volume was sound.

SONORITS

I play hard rock and metal (70's / 80's / modern thrash genre) and unlike what some say, YES c'st possible to have a big fucking her saturates !!! Just:
1: whether the lamps are not dead or otherwise not bother to post a comment !!!
2: have good hp (personally a fact largely the case in 1936)
3: having a good scratch (for me vigier exca Di Marzio tone zone, bam pro and also with super distortion affects mapleneck / sg std / les paul std Burstbucker alnico / jackson Seymour Duncan tb4 rosewood / Charvel San Dimas ditto plus 59 handle Maple and touches everything in standard tuning either re re diese diese either with low E string pulling drope 10/46)
4: Learn to play !!! and have something to compare! (I have not bought amp poorly lamps)
For me JCM900 synonymous with precision and feeling, nothing to do with the JCM2000 and jvm, this amp is the last true that sounds like marshall marshall!
Remember that it has created and to counter the Soldano and other mesa fashion in the 90's and the permetre schreders and metaleux to stay at marshall.

Here are the sounds /
clean very good for a marshall (useful for connecting a distortion)
clean with good gain for blues, AC / DC, Led Zeppelin
od very classic rock
od with max gain good for hard rock
od tube screamer with a view equalizer and it's perfect for thrash metal (precision with harmonic = hell solo)
with serious tuning and good mics = palm mute clear and punchy; cavalcades thrash (Metallica, Megadeth ...)
The reverb is pretty cool
The equalization may seem innefficace but I find that c an advantage is not going 2:00 settle its mids for example; here it sounds now.

el 34 or 6L6?
I will say that the 6L6 are more roots than the EL34 without losing the precision with more harmonics (very hendrix crunch)
El 34 drive bottom episodes with tube screamer are more modern with a thicker grain (personal opinion) stridant least as in the treble.

Hi Mode or low?

As low sound is softer fatter less precise because less powerful (50W)
Hi are over sin and shine but it less manageable small volume, must push for a ring!

NOTICE GLOBAL

I recommend this amp to anyone who row to find a good sound with the recent stuff often too expensive, too cold; complicated and not reliable enough; if not love good grain marshall c c'st not for you !!!

Amp originally fitted with 4 x 5881, I did change to support 4 x EL34 "Mulard".
Amp 100W, 50W in swtichable (triode: loses power but also the characteristic)
2 foot switchable channels.
Channel A: clean -> crunch
Channel B: crunch -> overdrive
Loop insertion effect balance with -10 / +4 dB

UTILIZATION

2 amps easy to use switchable channels

SOUNDS

Suitable for Blues, Rock and even Metal.

OVERALL OPINION

Used since 1998
What I like: Channel A cranked overdrive with a good front.
I also like: changes made to the channel B (diode bridge split) which gives a closer rendering JCM 800 punch.

100 watt head lamps .... The settings on this head are not at the forefront .... not much opportunity since SETTINGS pots do not respond on a large beach .... but we can solve this small lacunne by purchasing a pedal of equalization (boss ge-7 for me) and you realize that some things holds big!!

UTILIZATION

For my part, the configuration is quite complicated .... I have two speakers who will lead in 1960 with A + B. ... connectivity is quite complicated, I had to look on this site for the information necessary .... but with good advice I got I am absolutely very happy!! I did not get a manual with but at the price I paid I even had the 1960 A cabinet with!! sound of the amp is very good if you look for rock sounds .... but we must add effects to get the big sound ... its very hot and the distortion is effective wish a very good clean and also easy to find!

SOUNDS

I like metalheads and rockeux .... this is the amp of choice for my type of player .... I use a digital delay, a chorus and a set of preamp eq ... j ' addition follows a ibanez tube screamer overdrive for Narrow my sound and have the teeth to the metal ... the sound is really good ... in 25 years it is my hobby and best sound is the sound I was looking for! !

OVERALL OPINION

it's been 5 months that I use and I'm very satisfied ... nothing to do with the small combo amp and other fine good cheap!! that I like the most is that it is big, yes, but the sound is diffuse Surprisingly ... with 8x12 inches behind the ca pouuse and spreads halucinante way!!, as I bought it used, I can not I really pronounced on the value for money but in my opinion worth it ca pay dearly for this type of amp .... moin has to have a changing temperament, he will follow me all my life I think so! !

I might be a desire to spare EQ 2 channels ... otherwise the rest is classic (and relatively complete)

UTILIZATION

The use is bone simple, any guitarist capable of holding three agreements need not open the manual!

SOUNDS

The party is the most controversial ...
Personally I have used for years with a Les Paul Studio is jousting without effect supplmentaire and I've never had a complain. However it is true that the sound palette is very tense and his "Marshall" is rather (too) easily recognizable ...
I think it's a very good choice for all that rock a little pchu ... For the music more "soft" options may be a little too thin for what is harder, the channel distortion is, in my opinion, not enough fat and Dfine.
But what is the alternative, punk rock, etc ... it is really very good!

in résumé is not the best choice in terms of Polyval

OVERALL OPINION

I've had ten years (ouch ... I'm getting old and at the time he has really matched my expectations ... over time, tastes change and I am a bit "lassquot; sound. I" bypasses "the last few months I prampli replaced by a Rocktron Voodu Valve, since it takes advantage of a second youth)

Now I think it does not compete in terms of possibilities with the current models but ... I think ultimately it's an amp that has some me (this is rare) and I am a hard Sparer

JCM900 4100 dual reverb series.
all lamps (3 premp, 4 amp).
100w power.

UTILIZATION

My utlisation is notament is for the big rock, rock and variety (style-M-). with an epiphone Lespaul Standard.

SOUNDS

The sound should lead to a suited my style of music (Hendrix, ...).-M-warm sound.
the guitar part with a wah-wah morley and that's enough for one of his mythique.pas need to go through tons of pedals and rack ...
its clear this is not the same, because the amp crunch right now (especially with the wah-wah). but the sound quality is good trs.

OVERALL OPINION

As the pass transistor, a hybrid and a lamp (all from Marshall). I am a marshall trs typ. This head is perfect for me.
those who say it's not great do not understand the approach of a notice

Good, quick reminder:

This is an all-tube amp, 100 Watts, 2 channels. The connection is simple: Between guitar, footswitch, and rear of the BTE, an effects loop, two speaker outputs, and power supply. At rglalge and effects, it is the bare minimum: gain, 3 band eq and reverb.

The eq is not efficient trs, and rverb plutt brittle over time

UTILIZATION

The use could not be simpler. It's true plug and play. One branch and it works!

SOUNDS

Ha! This is the beginners that the rat race! Personally, I play blues, pop, rock, and especially the progressive mtal mtal and industrial. I jou on many amps (Mesa Boogie, Line 6, Peavey 5150, ...). And I came back to Marshall! Why? First, we must prciser that no two sound like Marshall. For some reason. Then it's an amp that is "tame." Also, you really think in terms of torque guitar / amp. Personally I play a Les Paul and The Beast Custom Lag. Finally, this amp does a brilliant Vincent compltement tampering by the Liberty Rock Studio. Power Has compltement redone, the circuit also rverb, and the amp is fitted exclusively lamps EH. Feedback, there is no extraneous noise and the sound is warm, dynamic, rich, either in clear sound with distortion. Especially since it all out on two Marshall 4x12 cabinets. For résumé, I get a sort of mix between a Mesa Boogie and a JCM 800. During live performances of my group, I actually many guitarists who come to me APRS saying "we never heard a Marshall sound like a. .."

OVERALL OPINION

I use the bte the past 1 ½ years. I love the sound, versatility and its ability to highlight the guitar that I plug it. APRS trying moultes combination (Mesa Boogie Rectifier, Peavey 5150, or POD + power amp), I fell madly in this amp bought used for 600 euros with two 4x12 cabinets! At that price the more, has not refuse, even now and I plan to buy one deuxime!

Any amp head, 100 watt lamps with lamps, dual reverb that is an adjustable reverb on each channel (clear and saturation)
Effects loop connects to the back (send and return), can reduce the output power to keep the heat without power (though effective)

UTILIZATION

Config super simple and intuitive.
After one day, after testing and adjustments, is adopted.
It's a basic amp in its design, but he is quick to find a wide variety of colors and heat.

SOUNDS

I play rock, very fat, very big and there is the foot. This amp, it always kills me for 10 years.
I have two guitars: Les Paul and Ibanez jem 777.
The Paul and the JCM is a couple, they are on the same wavelength. Anything goes. The most saturated to crunch huge very big and warm, this amp is beautiful. The harmonics sound, the amp sings, it twists, it's hot almost burning.
I can compare it to two other amps that I bought in parallel, and passion that I have. Mesa Boogie and Carvin, the dux all lamps: I kept one, the JCM 900. And I'm not ready to sell it.
Only flat, clean sounds sound better with the JEM, but with the les paul, it is very pleasant to play tight or small ruthmiques arpeggios with reverb on 7-8.

OVERALL OPINION

Used for 10 years
This is a serious amp that tears
Yes, I have tried many styles by his passion, I bought 2 (see above) and no better.
I paid 8000 F at the time (1200 €) and how they regret?
I do not know what I would search other amp modeling effects? I rest on authentic sounds, mega hot, with an amp that I am screaming and defending itself.

100 Watt lamps, my 5881 model is equipped with amplification.
Sufficient connectivity, effects loop and speaker outputs on the rear.
Basic adjustments on the front.

UTILIZATION

Very easy to use, the balance between the two channels is easy to do in order to have a clear and balanced levels of saturated sound that is not always obvious.
No need for manual is very basic and simple.

SOUNDS

Against all odds, I was amazed by the clean sounds that come out of this amp. Marshall and clear for me, it was not compatible, then I'm on the ass. While this is not a Jazz Chorus, but the clear one grain of its own and I like good with both strato, TV LP.En that address many clear channel, one can have a slight crunch to very nice blues, just playing the guitar volume.
Saturated when the channel is a marvel to him. Attention not Trash, metal, or other derivatives, but for blues, rock and hard rock, this is his 25 years of history. AC / DC and consors ...
That right, dynamic, powerful, if necessary.
A report, it is possible to have good sound saturated even at low volume.

Accepts all possible modulations in the loop. Boosted channel is sufficient unto itself, or we go to the volume knob on the guitar, or you put an overdrive ahead to warm even the lamps for the lead.
Small flat, tone corrections are not extreme efficiency.

A point, my head is connected to a 4 x December 1960 all lead is most basic, just careful in tightness.

Only major complaint was heavy and cumbersome.

OVERALL OPINION

Often criticized, this amp is often not used to what it was designed to do: Rock'n roll and hard rock.
on the other hand, with just a guitar live in, there are already what to do with a good variety of sounds, without leaving the particular grain Marshall.

And car with large trunk required if used with a 4 x 12 cabinet.

Pramp ECC83 and 4 lamps in 5881 (6L6) in amp. All lamps 100 watts.
This is another version of the Dual Reverb JCM900 placing on the market it was released, as sometimes Describes with EL34.
The sound is more in the spirit of Hendrix or JTM45 JCM800 that the trs hard rock with EL34.
Connectivity classic faade a single input, footswitch input for a two floors clean and pramp Lead (distortion). Two outputs with adjustable HP 416ohms, an effects loop in / out, Line out output, a 50/100 watt switch output level DSIR.
Rglages quite simple: Master volume, reverb and gain for each level, Prsence / bass / mdium / High together.

UTILIZATION

Config prcis trs simple as above. a clean, one lead.
The sound is pretty easy to find if you like Marshall and if you know the kind of color research. For my part, often making the hard rock and heavy, I use a rack full of effects, including distortion, and I plugged into the Clean, the gain background (no distortion), master or 5 6 with output level of the rack rather soft, prsence 9 or 10, 8 bass, mdium 2, 3 treble .. Used the fact that these levels provide floor with all the fun lamps chattoyantes ... all on two cabins in Greenback and G30H

SOUNDS

I like the sound Marshall for 30 years. I still have 6 Marshall amp heads home, DIFFERENT MODELS (I know, it's a bit too much.
Gibson Guitars Lespaul and MusicMan, Gibson pickups, Dimarzio and EMG.
Everything is feasible if we know understand the bte ...

OVERALL OPINION

Since 15 years.
My only concern is his weight. Unfortunately, with large back problem, the heads JCM800 and 900 are no longer for me .. I spar several heads of this kind. I still have one which I can not dernire Sparer me ... I am a sentimentalist.

A tube amp toutte ... View stats for other

UTILIZATION

I'm only serves as "juice" ... There is that in my practice and it makes very good apareille

SOUNDS

I have a line6 PODxt Live that I plug into the clean channel I have a setter for its clean without my usual effect of pod after I set my sounds in my pod is only the marshall spit sauce and it makes it very very VERY well I would put the flight 6 and whatch out because it smashes your ears!

OVERALL OPINION

I toutte the power of a full tube amp with a digital sound studio at very high volume without feedback Bébitte bullshit kind of

On this head amp is not perfect but for the fact that I use it makes acsenseur really good!

100 watts all-tube head has two channels:
- 3 12AX7 (I juggle a bit between The models I like: tung gold ground, Hey, LPs, and China 12ax7B)
4 EL34 (Groove tubes for my part)
- A 4-band legalization
(Bass, midlle, treble, presence) for both channels, but ultimately damage if Gnant.
- 1 SETTING THE rverb indpendant for each channel.
(That's gnial by against).
- Two volume and two CONTRL gain.

Connections:

Faade of:

Between a jack for the guitar
A footswitch between the two tracks.

Rear:

An effects loop with rglage
Two outputs for recording: A direct (sound pramp not filter)
A filter for recording purpose.
Impdance switch (8 or 16 ohms)
A power switch Low or high)
HP output.
Two fuses with LED lights indicating when the lamp is dead.
Gnral a fuse. ACCS easy all the fuses)

For me it's team in Fully Groove tubes. (EL34 amp in)
10 compltes connections for the switch to impdance, and output power.

UTILIZATION

Using ultra simple, easy to handle.

SOUNDS

A Clear Channel / Overdrive:

-> To the sound of this amp (and even any) I recommend a 10-band equalizer. I found a home RgE10 boss is 40 euros. It's fantastic! The sound is incredible proportions! The original sound seems quite flat, it really has to try and serve both the blues rocker that Aguri of all kinds! For cheap you rediscover your sound Fully and I do not even speak the clear! <-

CHANNEL 1:

Clear
I t trs also surprised by its clear, sweet music.
Without being among the most impressive, the sound is simple but the fact remains that they are rich and can play sweet things without damaging the eardrums. Or a good chorus and flanger ca does it well!

Overdrive:
Impressive accuracy! Carr was dead! Arle pile on the ropes for the Ac / Dc well surly! The SETTING THE prsence can bring out the grain finnesse. A good grain ar a desired thickness ... gnial! Heat and density are waiting for you!
I rather like to push the volume and the gain of Channel 1's for a good lamp.
Channel B: OD / Disto
CHANNEL 2:

Disto:
A gain level, I want to say it, enough to make the maiden metallica and other. If you possdez an overdrive pedals to boost Do not hesitate, worth a peek hours .. ear!

Trs compress the grain is compared to the other two. We do here has aa much more muscular sound than the rest. But the major problem (at last I found is that it really lacks mediums ...

The sound is heavy cras and trs. So I do not know if the era was c'tait the goal but lacks a bit of momentum. has reminded me of an equalizer "V". You know the young mtalleux 18, who cut the growing medium and low?! lol rsultat emerges at all in the mix and the sound gives no shade ...

Overall the amp once equalize spring, there are fast muscle Marshall sound equalizer. ) For channel 2: Eq mandatory!

The sound is good trs as a whole, the distortion is in mute trs own course and even more after stroke by pedals.

The low and high modes can juggle between two colors, is low in acute soft, less dynamic overall and trs sounds good for blues. In high is richer and muscular perfect for live performances.

OVERALL OPINION

An amp that juggling a Hard rock blues. Good reliability of the head in it even is well mounted and trs aa look more than solid.

The sound is missing characters and frankly it's not an amp that promises hours of fun! The power is ample, the grain is good it's good that Marshall can dgoter for cheap .. (400 euros for me).

As said one of our friends here as I pass by almost as Marshall, he's a perfectly fine with me waiting to put a little more for a 800 or more an antiquated genre plexi et al. .. YUM!.

It is not about an ultra high-end amp but for a while first lamp seems a good choice trs:

You want to go to any lamp, you're tired of your transo but your budget is tight?

DARK DARK DARK!

JCM 900 4100

Dejate everything said about her

UTILIZATION

The JCM 900 is very simple to use, very simple

Regarding the sound, it must be admitted into clean is a bit stiff at the base, and not saturated trs a metal base that's true ...

SOUNDS

For it is the cons that have become interesting, using the JMP avecun 1 and 1960A with a more or less different guitars: Jackson RR with emg 81, emg HZ LTD7 strings, Gibson Les Paul Standard and a squier strato di Marzio with a microphone, the sound is really metal and hardcore!!

Ke the fact the sound is not typical in trs clean, my friend, a JMP that does the job and it really trs trs well lol
It sounds really metal, TRS big sound and the JCM 900 trs filled out its role of power amp!!

He is strong, too even, but its role APRS all.

Try for others like peawy, the mesa and other JCM 900 is really the height, if you like big fat are well and that we love against less acute Submitted too, the JCM 900 and JMP 1 are unstoppable.
It passes easily obituary Hatebreed and really does not sound like fear or deftones slipknot ...

OVERALL OPINION

In 10 years of loyal service I do not resell any time soon!

It is beautiful, sounds like hell, and impresses with its simplicity and power <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_wink.gif" alt="wink" />

I also possde peawy, trs good too, but different, the JCM 900 is built for him laseine !!!!!!!! <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_mrgreen.gif" alt="mrgreen" />

I got it used, I board is jamaist deu

If you like Marshall, metal, EMG lol the JCM 900 amp is a really great !!!!!!!!!!!!!!!!!! <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_mrgreen.gif" alt="mrgreen" /> <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_wink.gif" alt="wink" />

Do not hesitate if you see him, it will be a great companion!

Lamps (Power & eq) 100w 2 channel
I'll spare you a description ... eq for each channel it could be fun! but are not!

UTILIZATION

There is no simpler, no need to adjust the hours it sounds!

SOUNDS

I played noisy, punk, rock, indus, with a rise of 70 SG DiMarzio, a Mustang Us, a Heritage ... and never disappointed! In Briefly, crystalline or clean sounds I do not know, although with the Mustang and the channel A of the amp the sound is more than respectable wholesale with single coils it goes well, we can play funk fusion Red Hot ... but we chose not to its characteristic crystalline Marshall ...


OVERALL OPINION

I use that since there is, I'm also JCM800 master volume and a few others but this one I do not loose! The scratch who tested it all appreciated . But then I tested the version with the 5881 and there I found no sound, nothing to see, I also tried the 2000 I can not find it better with buffs that are useless if not have a sound yucky!
This is an amp that is not expensive OCCAZ and with a good selection of lamps it does! Otherwise the little negative point is that the knobs spit, as usual! After years of bomb I'll have to contact me decide to change them!
