I play Classic Rock in bars on the weekends. My main band uses no amps on stage, all Pods and electronic drums. I'm in another band that requires me to have an amp on stage. I've got an old Carvin 2x10 and 1x15 plus Pro Bass 300 but I'm not happy with it. I'm wanting to place my bass pod pro and a poweramp into a rack and just use 'cabinet x' when needed. A lightweight cabinet would be a plus. Any recommendations?
