I play a fretless Jazzbass Deluxe in a jazz/fusion band. I am currently using a PJ Briefcase and the tone is very nice but obviously is not going to be enough for gigs. We are drummer, guitar, sax, keys, voice (30% of the time) and me. I tried my '71 Superbass and the sound is great for rock but not for what I do now. What would you recommend me? I could spend something like 1500. Thanks guys!
