Marshall 100watt with a lamp in the preamp is in the rest transistor.
It 100watt do as I stated above.
Settings: there are settings for the clean and overdrive (there's only one for both a shame.) And setting of each effect:
for clean and overdrive are: gain, volume, bass, midle, treble.
for effects there is a knob to select the effect, the other to adjust.
effects reverb, flange, delay, chorus etc ... (About 16 I think)

UTILIZATION

Even if you're used to a much smaller amp before with fewer adjustments etc. ... sen is very easy out.
yes good sound is very simple to optenir, it also depends on the style play.
the manual I do not read is not even open (it's not that I do in it he explains the precote taken with a light amplifier)

SOUNDS

Is it your style of music? I play different style enormously to progress I play as well as funk ska punk etc. ... it is very Polivalente.
My guitar is a bass line is going to say but I get a sound that I find okay with this amp, I do not deffet those of his amp emplement sufisent.

OVERALL OPINION

I use it for about a me now.
Or the price I had is it More than a case (I do not siterais)
