I use it for everything! Big sound (especially rp) and jazz / funk / groove. This is an amp almost untraceable today (mine is 1973, there is not even a plaque for the components, they are welded directly to the other one!), And I'm really super happy to have been able to get it! The sound is full but never aggressive, lamps give the best of themselves in screaming high and power of the whole is more than enough to accompany you everywhere!
So next config, there are two clear channels, no distortion / crunch / overdrive, to make cruncher, it would push the pre-amp thoroughly and there, even with the volume at the kids, you kill all the ears people in the room .... There is also a classic spring reverb and tremolo (but only on a channel).
The settings are simple (3 serious knobs, medium, severe) for each channel but really thoughtful, nice coloring matter what.
Its big advantage over a twin, is that he knows to be brilliant without breaking your ears!
