I'm not familiar with it, but on the Super I built I really liked the stock tone setup. It is very responsive, more so than any normal modern amp I've used. Where I was used to bass and treble knobs adding a kind of presence and overtone effect, the Super - and I assume the Bandmaster - tone controls were more of a "drive" for the bass/treble. I could get some cool Hendrix-like tones by boosting the bass and leaving the treble more midway. Instead of adding more boominess to the sound, it was only overdriving and compressing the low frequencies while the high end stayed relatively clean and distinct. Of course, you could do it the other way or any combination in between, but it just had a sound to it unlike anything else I've played -- clear treble with breakup if that makes sense.
