I love it. It's a pre-Gibson AH600SM7, and it RAWKS! I'm running it into 2 Avatar CB112s-- one through each channel. It's supposed to put out 600 watts @ 4 ohms-- 300 watts/side. I've got each 8 ohm cab into the separate channels and it sounds just great. I tried daisy-chaining them together but it seemed much louder when they were in the separate channels. THe EQ section will take some getting used to-- it's got 2 pre-shape switches; a 7 band eq with an output level control, plus an in/out switch; there is also a knob for the eq that can be set for emphasizing the lows, the highs, or flat (it rotates kind of like a blend control); plus the normal gain and volume controls. The amp cannot be bridged, but it's still really loud. There is a really cool built-in black light that illuminates the front panal-- but it doesn't work. That's about the only thing that's wrong with it. It's built like a freakin' tank-- weighs in at just over 50 lbs (22 kilos?) and came in its own tolex rack. I'll use it live next Friday and try to give a full report after that. All in all, a really kickass amp. Does anyone know where I can find a schematic? I want to repair the lamp.
