Marshall 2104 JMP Master Volume Lead [1976-1981]
Lamps 50W combo amp dlivrant very muscles ...
2 EL 34 and 3 12AX7
Mine dates from 1978, the receiver is rustic, front: 1 between a high + low, then the knobs of qualisation, Pramper and master.
At the rear, to add between two cabs and a slecteur (good practice) Impedance who can choose between 4.8 and 16ohms
T appear to have components built to last.


I do not m'tendrai on manual ...

The clean sound is never really clear, the crunch is sumptuous, and the gain does not produce a background saturated fat but a big crunch MUSCL type ACDC.
The treble can be a bit low volume presents but this effect fades away in a little amount of the master, a modification that turn a capacitor (brightcap) exists but I can not find it necessary to my amp.

The volume is very high, the 50 W are (too?) Hear a attnuateur would be welcome to enjoy the lights of this toy.
Equalizer is slightly better than the new Marshall without being either a model that has the knobs are not very specific on and we need to correct EXAGRES frequencies.

Finally it is a single channel, so you get no sound 10000, must love the grain on pain of being Marshall's


I play rock muscle and this amp is incredible, we pass a beautiful big crunch sound (via a pedal of saturation), which allows me to do without the riff bp ratm.

I've had with 2x Celestion G12-65 that looked like too much to G12T75 is to say very good sound for a Marshall with the winning kind bottom ACDC or Led Zep ... just a bit on the other hand ds ventures that using a pedal on hi-gain sounds.
Mountains once a V30 and a G12H30 Heritage, we lose a little crunch by crmeux the cons in saturation through a pedal capable of saturating the fire.

I play through a Gibson Les Paul Studio, and then through a Shredmaster or Artec CoolDrive.
At versatility is 0, this amp does 10,000 sound, but what he does he does well.

This amp is amazing, the sound has a personnalitun ct surly and uncompromising specific vintage marshall and Me I'm Falling in love is the first time in 15years that I said TIMES "yes that's what the hair cell that I want ..."


I have for some time now, he accompanied me on stage is either repeat, and as I already said I'm in love.
It is a rustic-channel amplifier that has a particular texture and a real personality, but the sound is good regardless of the quality of the guitar uses it.
One True inconvnient: it really PES does the weight of a death ...
I brought the U.S. a reasonable price 800E, compare with the 1200 E ask for some. It is a rare amp combo version of the document o leve.
With exprience, I do it again 100 times this choice.
