ahhh, my first "real" guitar head, which I used from about '90 until '94 maybe. never knew chuck from death used one until recently. there's some youtube of him playing one live, and his did the same thing mine did: feedback at high volume. it doesn't get loud at all. sounded more like 40 watts or something.
GREAT for recording (not direct mind you), very full, bassy, nice distortion.
people would probably call the distortion weak these days, but I think I'd still dig it.
i stopped using the effects loop because everytime i did, the amp would get screwed up, even after the effect was unplugged. had to get that issue fixed several times.
i miss it, and may get a 1-12" version for shits and giggles someday.
the newer line is junk compared to it.
