I'll list the ones I've seen recommended over and over again, but I am interested in what lightweight options are out there and I want this thread to be more of a reference for other players that are having issues. I have had back issues since I was involved in a bus accident about 14 years ago. I ended up wearing a neck brace for about 3 weeks and never thought about it again. Recently, my back has been hurting non stop almost every day. Playing bass further aggrevates this and while I haven't weighed my current main player, I would guess its around 10 lbs. So, some basses that have been recommended previously: Yamaha RBX A2 Fender Aerodyne Hofner or other Beatle bass You can't tell me that everyone with back issues plays these three basses exclusively so what else have you all been playing? UNITE!
