Scott home stereo amp (solid state) 40 watts per channel, run through 2 or 4- Celestion speakers from 1973 or so(probably Greenbacks, don't know). The frequency response wasn't limited like a guitar amp, it was full 20-20,000 and it was the fullest-sounding amp I've ever heard. And it was so clean. I used a DOD overdrive pedal, and though it was crap compared to a tube screamer, I was ecstatic about my equipment. I play hard rock with a lot of clean. For a while, I owned a Randall 120 watt head through 4-12" somethings, but it was dead compared to the Scott. Though I didn't use it after about 1998, I owned the Scott from 1976 to 2005 when it finally said bye bye and fixing it wasn't worth it.
