Transistors, a channel but ... trs INTERESTED gains as two cascaded over a master volume. Eq 3bandes speaker refined and basta.

UTILIZATION

No con at all, these two gains cascade. The first gives a fine grain, the second a much larger grain. Kind of saturation prampli / power amp saturation, relatively guards.
With a little practice and at least one ear that costs all sounds are possible and with more class. Of course a musical issue s'arrte yet saturated, the styles (or lack of) current will only be achieved via pedals from beyond the grave (HK warp, line6 uber metal, get the idea). And two gains can clean sounds varis in structure and not just their legalization.

SOUNDS

Amp fabulous, nothing better to advance the guitar sounds. 2 cascading gains over the guitar (and its buttons are not on / off ...), anything is possible, no excuses.
Trs good for blues, rock, variations of play

OVERALL OPINION

Only ppin, Drouille the knobs from time to time, normal.
No effects loop is a shame, but that's all I rouspter.
These bikes are rare in plutt okaz, so you Precipitation Occurred any manner.
It seems that all these amps Park taient of the ball, not the thundering Marchmal
to have ceased production (too much shade to "real" stamps marshall).
Awsome little amp so.
