Ok, a trip back to the '70s... What prominent bassists used the Sunn Coliseum Bass Amp? With Beck, Bogert and Appice, Tim Bogert used one (or more) with 4x15 Altec loaded cabinets...dig that tone on BBA and BBA Live!!!! Chris Squire used the Coliseum Lead amp and guitar cabinets. Ox used Coliseum Slaves. Who else used the Coliseum Bass head?
