Over the weekend I acquired a 1972 Sunn Concert Bass head in working condition--free! It cleaned up well and is fun but I don't think I'll keep it. It's just begging to be played through a 2x15 in a 70's Zeppelin/Who/Hendrix tribute band, which isn't my style right now. Anyway, if anyone remembers this amp, what's the story on the distortion circuit? The head doesn't have the footswitch to turn it on and off, so I bridged across the footswitch inputs with a phono cable, and the amp got a lot (I mean a LOT) louder, but still sounded clean to me. The trouble is, it was so loud I had to roll off the output on my bass to almost nil. I suspect it needs to be cranked up to really hear the distortion. FYI, it's a solid state amp, no tubes.
