Recently I've been having wrist pain after my longer sets. I'm fine with the shows that are 30-45 minutes, but its the 2 and 3 hour shows that are really killing me. I play a Fender Precision and I am a smaller guy at 5'5". I recently played a mustang bass and loved the feel of it. I can only afford to have one bass so I would have to sell the P bass to fund the Mustang. Would I be making a huge mistake in doing this? Would a short scale make that much of a difference in the long run? Is there something else I could do to help with the wrist pain? I really need your help, thanks.
