I THOUGHT I could see pixs of it, but I guess not and I have no idea what this is. It looks like it might be a rack mount - but I still need some idea of the age and what it's capable of. I have an eye of a used one for a pretty decent price - but I need some info. It might be nice for a practice amp - no? Not sure I would jam with it, but is it a pretty good quality amp? Is it a tube-amp?
