Bass, could be any of my P basses, fretted or fretless, spector, Steinberger, Ibanez musician f/less or stagg upright.
Ampeg PF-500, set flat, ultra bass switched in, mark bass club 1x15 direct into the pa. No fx. just bass, cable, amp. When I see video clips of my lot live, I'm always amazed how nice my bass sounds.
