Amplifier mosfet transistors (ie transistors that went up there quite a few years now, but who are known to imitate the better the sound of the lamp). 100w is more than enough.
for the connection, everything has been said.
for settings, there are not many knobs, spring reverb very nice.
EQ has nothing to do with a band from Mesa, but that said, you to piofiner with some stuff)

UTILIZATION

Setup is super simple.
for sound is the sound marshall.
I had just filled the marshall and tested many others, all lamps, hybrid, or acoustic.
in fact, it seems that the head only gives the grain marshall, and warmth to the sound. it is not at all garish (contrary to what one might think of a marshall transistor by comparing for example an vs100RH you pay 3 times cheaper but the sound is horrible).
the grain sticks to the skin of each sound that you make it may be inconvenient for some users.
the manual, for use in everything from the back of the amp, for someone who is not used, but otherwise not need

SOUNDS

Suitable for any style of music except metal.
I play with a Fender Stratocaster Japan 80 years.
you can play your scratched directly on the clean channel, and there, those critical of the Marshall clean channel sound will be surprised by this one out (AC only applies of course not clear a twin or a JC- 120).
I personally only use the channel full. with a small multi purpose, you get a good range of sound that allows you to do everything (on the contrary, the clear channel, the sound is very small, and quickly turns to his crappy).
I use it especially with gt5. the sound is just awesome.
believe me, you wonder if there are no lights hidden beneath.
I often changed hardware, I have a preamp access to H & K is among the best preamp out (direct competitor at the time of ada mp1 and TriAxis first version). he smiles and not the poor.
with multi effects and amp modeling marshall, happiness.
although distos and modeling of gt5 have the rating on this amp, they sound great.
I still can not see how the transistor can provide a magical sound such as that the. (Of course, it must help a bit like any amp, just with a scratch is a bit hard, it's not a vetta!).
this head, it had better be classified as the same as a vintage JC-120.
it is really worth.

OVERALL OPINION

I have 4 years
feature like most grain, you have an easy or a red hot Louis Bertignac, or any other group using marshall for that matter.
I like the least? drive. the clean sound, it is not bad when used only with its simple scratches, but in practice it serves no one. you can get a clear sound with boosted channel and a multi purpose (a clear super hot and more).
value for money? Well, we find more. but as the JCM800, it's worth much more expensive now than when it came out.
with experience, I would do the same choice that is, try the amp before.
mine runs like a clock, but these are the 20 amp, 25 years old.
So voila, there is often something that kidding.
That said, if you try using this kind of pice of collection (or even purchase), please
