iamqman's review"Classic old British tone"

Marshall 4210 JCM800 Split Channel Reverb [1982-1989]
Marshall amplification is one of those iconic amp companies that is so synonymous with the music world in general. They have been so easily recognize primarily because of the hard rock guys from the 70s and 60s who really put this company to the forefront for many people. They have such a great sound, great voicing, and pretty much any style of music around. This is one of those simple JCM amplifiers for Marshall that is a split channel JCM 800. The JCM 800 is one of those amplifiers that was almost exclusively used throughout the 80's. It was a great tone and had a fast pick attack that was used by almost every guitars throughout the decade.


You basically have two channels with a reverb unit and that is about it for features go. The clean and dirty channel is cool for the person who needs multiple channels but it wasn't necessary back when they made it and it eventually fizzled out.


If you ever played a Marshall JCM 800 amplifier and you know pretty much exactly the sound that you're going to get with this combo. This is a 50 W combo that has to split channels with a reverb section. So it has a little bit more features than a standard JCM 800 would have. You basically have your clean and distortion channel with a touch of a reverb unit. This is 50 W of power so the power section of the amplifier is going to be a little saggy and looser than 100 on amplifier > Usually hundred watt amplifiers have more headroom and they tend to break up in the distortion sound a lot later.


These amplifiers have been discontinued for a while but you can certainly find them in the used sections of many classifieds. They're pretty easily to be found and if you find a good one then you're probably going to want to hang on to it. These amplifiers were only made for certain limited amount time so they could be collectors items at some point in the future.

Marshall 4210 JCM800 Split Channel Reverb [1982-1989]
So mine is a 4210 JCM800 combo with 1 HP (Celestion G12 base) in 1988, he made 50 Watt, but it looks like it comes out 500!
Setting level there's not more simple:
a clear channel with adjustable bass and treble and volume.
a saturated channel with low, medium, treble and gain + volume. a master volume and reverb level and basta.
A footswitch to switch from clear channel saturated.


Given the limited settings, there's not much to do to get a good sound right, well, if it must wait until it is warm ... and then there! it rocks!


The sound is excellent, provided that we understand how to interact adjusting channel volume and master volume control. Wholesale or pushing the channel volume and decrease the master volume: its HighGain good hard rock 80's or otherwise and there is actually saturate the output tubes and one gets a good big sound boogie rock australian, if you see what I mean. With a good SG or Les paul there is direct.Par against it should not have neighbors, even with a 50 watt, it grows very strong!
on the other hand there is only one sound: the sound british marshall, volume 11.
Of course depending on the guitar is plugged to the beast, it passes through various horizons with a strat we have for Hendrix, with a Les Paul Slash (or Jimmy Page in the level of gain ;) with SG was a horn growing on the head, etc. ...
All the big legendary rock sounds are waiting for you to send that little wrist. and it handles well the history of volumes and gain.
For solos, I boost with a tube screamer Ibanez 1982 and here I am Adrian Smith Live period after death, with a DiMarzio Super Distortion that fat havoc.
Well, you understand this is an amp for hard rock fans 70/80 funky friend on your way!
I compared it to a JCM 900 combo too and it's still very different, so the identity is without problems.
Finally, the clean sound is not bad, it's not a twin reverb, sure, but there's beautiful harmonic and it is very hot ... not as good a JCM 900 on this aspect there, but hey it's clearly not designed for.


it's been 4 or 5 years that I have, mine was in very good condition when I bought it, it has worked well so far and the sound is really good a white-hot time.
Well, ok it is a bit heavy compared to the size, but who cares at this point. When you plate the agreements of the intro to "Walk all over you" ac / dc and you got exactly the same sound on the album Highway to Hell, well worth a few extra pounds ...
I do not put "perfect" in the assessment because in the style of music and / or games that can not do it at all, against for lovers of good old hard rock and roll 70's / 80's, it is pure happiness.

Marshall 4210 JCM800 Split Channel Reverb [1982-1989]
Tube amp: 5 amp lighting to: gain, EQ, reverb, and phase driver, puisances tube: 2xEL34
50 W (at bottom it breaks not bad ears) that power is interesting because on stage, we can push the master volume and to saturate the power tubes that deliver harmonics worthy of the legend of Marshal
2 channels: clean and boost

Front: 1 input jack. clean channel: gain, treble, bass (not mid). boost channel: gain, volume, treble, mid, bass. Section master: reverb, master volume. Power and Standby button.
not switch between channels, it is controlled by the footswitch. if it is not connected, you are automatically on the channel boost

behind: Input power supply cord europa, fuses, coach of supply voltage, 120, 220 or 240 volts, coach impedance 4, 8 or 16 ohm output jack DI or slave with volume knob (a sort of preamp out) , effects send and return jacks in, footswitch input jack


Few buttons, but many posibilities of settings.
Indeed, the clean channel sounds clean up to 5, and then crunch. Obviously, it depends on the lamp preamp you choose. Currently, I am with a Sovtek 12AX7LP. with the gain at 10, you are the AC / DC! c squarely on the drive, and lamp, Marshall JCM 800 Series ... Notice to connoisseurs.

boost for the channel, c even more varied. basically not good for the crunch, good for the drive, the gain is gradual, as lamps preamp, the gain may vary (I've tried various combinations of 12AX7 and ECC83, just by changing the lamp of tone controls, with the same lamp preamp, the gain varies ... it is a science which I do not know when we finished the tour undo)
It is ideal for all that is rock hard rock boogie blues, high frequency media, but can also sound "heavy" because many mediums may widen and will boost the bass. as I use it with a 4x12 cabinet "in the same series (celestion GT12-65), mama mia ouch ouch ouch!

must spend time on it to find his account


As a fan of Hendrix, I sometimes lose control of myself and fiddle with the whammy bar while turning around the feedback, before finishing by rubbing the handle of the Gita on the edge of the cabinet ...
basically, it's exhilarating c ....
Fender Start reissue 57 japan lag and the beast first generation: it sounds!

Obviously this is a rock amp, no clear comparable to fender, it is not suitable for reggae, jazz, funk, etc ...

spring reverb, very colorful, j'adooooore ....

the grain is one of the best marshall ...!!! simply, there are still better than this, but this family


I deliberately chose a combo of 50 W lamps, easy to carry (this is already quite heavy, these transformer), which can push the power for the sound of harmonics, and to which I add an external speaker as uses (stage / rehearsal).
the list of amps I've tried is long enough, I did not even launch in ... if there was a license amplificologie guitar, I sign on!

I have 5 years, I bought it secondhand € 450, then I did it by audio Retube maintenance in Lyon this year.
Today, I orient myself towards more flexibility in Monchoix d ematériel

Marshall 4210 JCM800 Split Channel Reverb [1982-1989]
It's a combo amp, 50W All Tube (5 x 12AX7 and 2 x EL34), 2 switchable channels, reverb, effects loop adjustable, HP original celestion 12 "(G12M-70).


I do not have the manual, there's no need for manual touch if your amp already lol.
sound, I soon found nothing + simple.


My dream this amp, I'm a fan of slash, therefore, have the JCM800 COUPLING my Gibson Les Paul is the foot. j'me even takes time to slash ds looool.
Despite the sale of its reputable clear marshall I think it's nickel just need to know to turn the volume knob on his guitar, because y 'who put their volume still scratching looool 10. I love the sound as clear as saturj 'am using more than many of my effects and my hand a whawha v AMP2 for the effects from time to time.


I had this morning, what happiness, to spend a marshall jcm 800 a vs30r means the diffrence lol.
Before buying my JCM800, I tried a marshall jcm600 and j'trouve that ca not see his level.
yes I would do the same choice.
