I was at Guitar Center yesterday and they had just gotten in a Sunn bass amp (it's seen better days) and was wondering if 300 is a good deal for it. I'm pretty sure that it isn't and that GC is just trying to screw people as usual. It looks like this: http://www.dangpow.com/~sunn/colibass/colibass.jpg As far as I can tell there is no fan anywhere and I read a review about heat problems. I'm going back for the Labor Day sale and need some feedback fast. I'm going to play on it, but for now I need some info: 1. What years was this particular Coliseum model made. This isn't the slave or 880 version. Serial number starts with "A". I'll call them and get the number. 2. Are these reliable amps? 3. What is a good price for this thing? I'm very curious. Maybe I can put my main rig on hold for a while and pick up a cool piece of vintage gear. Thanks guys.
