Marshall 2100 JCM900 Master Volume [1990-1992]
All tube .....


config very simple: you plug it sounds!


the "sound" marshall ...


it is the evolution of head jcm 800 mk2 2203 and in consort ..... even better because there a loop effect ...
amp is a "reference" when looking for the famous marshall sound .....
should not be confused with the JCM 900 SLX Newest: because this is not the same amps. (besides it to sound better than the JCM 900 SLX with my personal taste ..).
the only small criticism I can make it ... it is the lack of reverb ... for use with a multi-effects in fxloop you tell me that this is not very important in the end ... but hey, with the experience I buy a second property in fact ... well if I found in a secondhand! and it is not won because this amp is very very rare ... (It has been made that two years I think ..).
its just become a collector .... some say it is!
collector where that is rare ca ... "sounds"!

Marshall 2100 JCM900 Master Volume [1990-1992]
Marshall JCM 900 100watt head hi_gain mk3 master volume model 2100 (that's the ref for high accuracy)
_All lamp (mounted behind Sovtek) 3 4 preamp and power amp
_1 Input jack on the front and a footswitch input
Debian _to_ and send back for return effects loop, recording Compensated, direct output, impedance select (4,8,16 ohms), 2 Loudspeakers outputs (speakers), mode selector high / low


The configuration is very simple
1 guitar input, the switch to control the channel a or b
behind it plugs into a cabinet or other 1922,1936,1960 etc ... (personal Sovtek) and it rolls
the legendary Marshall grain is to go
like any tube amp, the head weighs a dead donkey, but much more practical than a combo.

on the front
A presence knob
A bass eq
1 eq middle
1 eq treble
1 A volume
Volume 1 B
A gain (sensitivity)
An overall volume (preamp)

is simple and very effectively
One can certainly dig the bass, midrange and treble but the sound is there and the change in frequency small, they're not alone I hate to take the head with all this.


pop, rock, hardcore, metal, this head is able to do everything
its weak point remains the clear sound of most of the marshall
its strong point, rock, blues with sounds fat and drooling at will (thank you Jim)
I would put 9 because I regret the lack of reverb (which I love so much in Marsall)


I use it for 3.4 years now and is happy that the
this choice I would do again as the know-how, reliability and sound on both this mythical album is to go
