Marshall 2205 JCM800 Split Channel Reverb [1982-1989]
Marshall amplification has been the leaders in high gain amplifier since the 60s. They are the best and most heavily used rock tone machines in the world. Some of their famous examples of amplifiers are the Marshall plexi and the Marshall JCM 800 series amplifiers. Today they have gotten even more modern in their building and features.

They have such a great tone and classic tone that has been featured on almost every rock album since their inception. A lot of the original Marshall plexi and JCM 800 amplifiers were modded by many of the guitarist back in the 80s and early 90s. In the late 80s, Marshall decided to release a split two channel JCM 800 amplifier. This would give you the users a multi-channel amplifier to meet the new upcoming musical needs.


This amplifier is very easy to use if you spend any time with the new modern amplifiers built today. This is it two channel amplifier with its own separate EQ sections for dynamic Ewing of the channels. You also get a reverb section and at 50 W of power this is no week sounding amplifier. The tone is very classic Marshall sounding and it takes no time to dial in that sweet spot for your tone.


This amplifier stays true to the JCM 800 tone but gives a more versatile experience for the new music at the time. This amp sounds very good when combined with a good Gibson Les Paul for a Gibson SG or even a Gibson Explorer guitar. Use that in conjunction with a nice chorus pedal and then you have a great 80s sound from the 80s amplifier.


This amplifier is no longer in production. You have to search the use market to find one of these if you wanted to get this tone. Many builders today build two channel 800 circuit amplifiers so that could be another option available to you.

These amplifiers I've seen on the used market in the classifieds for writer around $900. I would suggest getting a normal JCM 800 amp, as I never really cared for the two channel JCM 800 amps. This is a good amplifier for someone who wants versatility but there are other options to be considered when dealing with this type of amplifier.

Marshall 2205 JCM800 Split Channel Reverb [1982-1989]
(Originally written by joemanix/translated from Audiofanzine FR)
50 watt all-tube amp (five 12AX7 and two EL34).

Front panel:

Instrument input

Two channels:

Channel 1: clean and crunch sound (bass, treble and volume controls).

Channel 2: distortion sound (bass, treble, middle, gain and volume controls).

Common to both channels: spring reverb, presence and master volume controls.

Rear panel:

FX loop

Direct out with level control

Two parallel speaker outputs

Impedance selector (4/8/16 ohms)

AC power selector (120/220/240 V AC) for full versatility

Footswitch connector for channel selection

In short, it's quite comprehensive for an old Marshall from the 80's.


Two channels switchable only via footswitch (without footswitch, the second channel is active).

Enough sound control possibilities. Easy controls. You get the classic Marshall sound when all controls are in center position.

The combination of gain, volume and master controls allows to perfectly balance the channels.

Its 50 watts are more than enough, and its sound loaded with mids/highs really cuts through the mix.


The sound is present, it seems rudimentary at first but it's very effective.

It's a typical Marshall sound, the lows are not emphasized, mids and highs are strong. Distorted chord sounds accurate but the sound stays always warm and has the great ability to cut through the mix.

It's a typical rock sound but it's also very good for blues. The main advantage is the sound character. Don't expect a Mesa or Fender Twin clean sound. The first channel provides a crunch sound at high volumes (but it depends on the guitar).

The distortion of the second channel provides a big ACDC and Lenny Krawitz rock sound. The sound character is amazing. You have the impression that you're playing with an authentic amp.

Everything above describes the original amp, even though I serviced it and adjusted the bias myself.

Considering that these amps are easy to tune, I thought I could increase its performance. I first replaced all condensers with high-quality components (power supply and signal sections). The lows didn't increase but the sound became a bit clearer.

Small technical correction: the distortion of the second channel is produced by diodes. Some people say these diodes "help" the amp produce a higher distortion but the truth is that the amp overdrives thanks to the diodes.

After having studied the JCM800 2204 (all(tube single channel amp without diodes), I reproduced the distortion circuitry of the 2204 (V2) to implement it in the 2205. I had to add a 12AX7 tube, some resistors and condensers, and also adapt the original circuit to bypass the diode bridge.

The result: the distortion and the sound color are almost identical but the sound is much more precise and dynamic to get a more expressive sound.

But don't try this if you don't have enough knowledge, high voltages of tube circuitries can be dangerous and even fatal.


This amp is magical. I use it often with its reverb and without any other effect.

The amp is not very versatile but it allows you to play rock and blues, it's good enough for me!

Even if it sounds raw, it always cuts through the mix without a sweat.

Now that I tuned it I will keep it a very long time.

MGR/Troy Garcia's review"Marshall JCM800 2205"

Marshall 2205 JCM800 Split Channel Reverb [1982-1989]
I have been playing the guitar for 3 years and I'm currently in a band called Sendero Luminoso. My guitar hero is Tom Morello; however, my other influences come from Jimmy Page, John Frusciante, and Angus Young.

I paid an unbelievable price of 645 American dollars on eBay. Bids for this amp are increasing to nearly $900 and I was lucky to buy it from the seller. I mainly got this amp because I had heard that it has a great Plexi sound and that British crunch that I've been seeking along with some unique features.

The greatest thing I love about the unit is the sound. It's unbelievable each time I turn it on. I have the distortion all the way up and I still can get the feel of crunch in the sound. Another unique feature is that both channels could be mixed; if you turn up the volume of the normal channel while you're on the boosted channel, the normal channel's settings are added to the mix. Thus you have so many options and sounds with this amplifier. There is also an effects loop and reverb.

There is only one problem with the amp head, that is I get a lot of white noise. I don't know if it's my guitar, since it was custom made, or something else. I really don't want to buy a suppressor too. So I just came to deal with it and maybe I'll find the problem out. May be cheap cables? That's the only problem though.

It's in great shape. There's some very small tears in the Tolex but it doesn't have the sound of the amp. The D.I. knob is missing in the back as well but I've heard that Marshall made the knobs protruding out too far therefore many of them break easily.

This amp is great for many different sounds. If you like the crunch and "bad ass" feel of a Marshall get this amp. It has great reverb, channel switching capabilities and many more. I guarantee that anybody would be happy with this amp if you're looking for a sound unlike no other.

MGR/stefan's review"Marshall jcm 800 2205"

Marshall 2205 JCM800 Split Channel Reverb [1982-1989]
I got this wonderful amp though my guitar instructer who knew that i was looking for an amp. He had a friend who was selling it but really really didn't want to. If i didn't bought my amp when i did, he probely would of kept it. Not only I'm lucky to have a jcm 800 but i stold it for only Five hundred dollers. I have never seen this head close to five hundred dollars on ebay.

what i love about this amp is that it has that cunch that you can only get from a jcm 800. And whats really cool is that if you turn down your volume nub on guitar, it makes your cruch chanel cystal clean which you can not get out of the new marshalls. so if you had two volume nubs on your guitar you can set your treble pickup on max and you bass pickup down a little bit which would make your pickup slector like a distorsion swich on your guitar for leads.

Theres only two minor flaws with this amp. which are that it's impossible to find a person to mod it, i wanted to gain my own signture sound and it's a little hard to controll the volume and it's only a 50 watt. Whatever you do never get a 100 watt becasue thoughs are extremly worst. 50 watts is all you ever need.

this amp is One of the first marshall amps to have two chanels (clean/crunch). It's one of the first marshall amps to have spring reverb, i beleive. The quility of this amp is very good. It's older than me and it's in ship shape.

this is one of the best marshall amps you can buy. Many artists faver the marshall jcm 800 amps for a real good reason.

Marshall 2205 JCM800 Split Channel Reverb [1982-1989]
Joemanix see below, it is complete.


Simple. Like any good old marshall.

Unless the loop, it's hard to collect the digital effects.


his marshall. Without doubt one of the last to own the famous grain. We may say without being bad amp, the following have lost the soul of origin.

- Channel 1

May be clear as crunch.

For clear rather push the master volume as the volume channel, and conversely for the crunch.
The clean is transparent respctueux of the stringed guitar. By pushing the treble is the impression of playing on it sometimes sound quite impressive. Short clear sound very pure, very clean and the guitar will have its role.

To the sides crunch, it's old school. Always respecting the guitar used. I use it less for AC lacanl 2 makes this job really well and provides a medium setting and more.
- Channel 2

The lead sound channel 2 spread to a lot of style. Through the mid and treble knobs: frankly effective for once! vintage is oriented to a little more modern without problem. (Warning it's still very old school)

With this many mediums, not too much drive (The drive button is really active in the second half, so I hear by almost three quarters.) Is the boogie rock, blues, grain is fabulous vintage, still in respect of the instrument is short of pure bliss ..

Medium was halfway see less and boosted with od and is clearly another maiden and metallica that stand out. Of mutes to thrill, muscle. But most important point, one little cut medium the sound is piercing, spring mix. While muscle and power: the grain is heavy 80 ..

- For the rest:

The reverb is a bit too deep for my taste.

Regarding the effects loop and reverb are misplaced on the other hand. The reverb is before the loop. So your noise gate goes a little way to eat it possible ..

The loop when her girlfriend is not very gear with modern digital .. It blows and company ...


A great amp that does not demerit reputation.
Respect for the guitar, muscle, grain typed .. Truly a beautiful beast.


Loop rather temperamental, reverb too deep and misplaced.
Knob gain only half the active and blows very end of this race.

Marshall 2205 JCM800 Split Channel Reverb [1982-1989]
Amp all-tube, 50W (already huge ...), little brother of 2210. Instrument input on the front, Send / return back to the loop, direct out with adjustment knob and footswitch output.

Ultra simple to set if you have had would be only the most basic of amps in your hands.


The sound is almost right now, and what his ...


Haha here we go. I use this amp exclusively to the saturation, get something between the big rock and metal, and finally ... it is the ultimate amp for me. It has a grain inimitable! With an adapted speaker and a good pedal savament mixed it explodes all Mesa or other Engl 5150 and Randall and I've heard. It has a magical, warm grain to perfection, with a good reverb and a good guitar as LP or even BC Rich jur which I play, this amp is great: it is the last amp I've played. However careful and amateur New acnéens sound (rock or metal) the most modern, I do not think this is the amp you are looking for, it is more old-school, poetry. I do NOT resell ....
Not to put all hands ... this amp is a gem ... mouahç'éé% .1 a revelation and madness as you probably noticed,

PS: My opinion is up to me and objectivity that is the source, if I ZAPE Engel Mesa or other like hell, is by choice, and I played this for a long and unfortunate moment of solo correct, tried 5150, in short the best I've tasted was still in Engl screamer, by far, in short, each grain, each with its tunes, mine is clear and mentioned above. A word to the right ZIK


I use it for a few weeks before I had the 2210 that I sold too high because the power that delivered me unnecessary (and knowing that he must climb the flight he wakes up. ..)

Marshall 2205 JCM800 Split Channel Reverb [1982-1989]
50 watt all-tube amp ECC 5 2 83 + EL 34.Cette REPRESENTATIVES head at the high end with the Marshall 2210 amp that was 100 watts.Cet possde two channels: one for clean sounds and dvolu crunch ( 1 1volume treble bass 1) 1 for heavy distortion and super saturated (1 1 treble middle bass 1 1 1master gain). Common to a 2 channel reverb prsence 1 1 master volume.
One comes into faade; the rear we find a loop effect a direct output with its volume SETTING THE 2 HP for making a footswitch (channel change).


2 footswitchable channels, the simple rglages with corrections of a very limited effectiveness (as so often in Marshall). Still no doubt is the sound.


BIG ROCK SOUND. This gives all kinds of saturation that we want to channel 2 with 2 SETTING THE + master gain volume. The channel 2 is really the strong point of this amp. Despite all the channel 1 crunch dlivre clear sound remains good especially if you open the volume. Branche in a cabinet Marshall (1936 2 x 12 ") the sound is big, round bass with good Submitted and slamming, the sound is punchy trs


J bought this amp new in 1985 lpoque "I had a speaker 4 x 12" (1960 A) now requires back I have a baffle 1936.Le sound is still as big especially with a Les Paul the sound is HUGE. All sounds on this amp the stratos, the tls, that is a really great amp.

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

Marshall 2205 JCM800 Split Channel Reverb [1982-1989]
All-tube amp 50 watts, the only JCM800 with an effects loop, direct output (without simulator hp but hey!), A rverb!

Two speaker outputs!

So it's also the only two channels have a JCM800, with a clean and Bass Volume Treble more religious a gain circuit, which means that the higher up the volume, at a crunch!
The channel has saturated him a three-band low-legalization, mdium, treble, a SETTING THE gain and volume!

Masters, we find the rverbe the prsence and volume gnral!

7 out of 10 because the clean channel could bnficier better eq!


The configuration is very simple, you plug it all and sounds quite easily!

Marshall then it's not worth it to spend three hours paufiner the rglages, turn some knobs and presto, it left my kiki!


It is ideally suited my style of music (big fat rock pchu well!) But its weakness is clear sounds cruncher who start high volume (if you want a crunchy sound, a sound trs well, but for its clean trs is rat!), the clean may be a little more singing, it's the incisive trs as a channel, but at the same time possde a super dynamic!

Saturated channel, is perfect, the clean lgrement crunchy crunch through the bluesy, rock and heavy rock up, it works great! It sounds trs round and warm and has plenty of crunch biting in saturated further!

Default of one little amp, it could have a bit more bass but hey, it may be to my power supply of condos 17 years of age!


I have for several months, I use a lot of time at home or in a group!

What I like about him is his ct a little old-school Rock and his par excellence and also its simple ct (no touch bass boost or mid boost or bright or trucmucheboost while is with the knobs), Marshall c'estdu trs good (unlike the current production!), which I regret a little bit against it by its lack of versatility, especially for clean sounds!

Before buying it, I thought my way to the JCM2000 as ENGL 900 and not liked (and I do not like!) Not at all, I also tried a correct (but hey, nothing to see even when is not the same type of sound at all, nor the same type of amp), I really did not take a Marshall and then when I saw the OCCAZ I jump over and told me that worst case I could sell it (to take ENGL me!) and then actually I liked it and I kept it!

This amp suits me at the right rock, APRS course it lacks some sounds but hey nothing is perfect! It's not a Mark 4 or GP3 either!
