I have a six string ibanez, and I really enjoy playing it. The only problem is, that my left shoulder starts to hurt less than an hour after playing. I have toyed around with selling it, but I can't bring myself to do it. It is the nicest bass I have also. I think part of the problem. Is that I have to sleep on my shoulders. When I sleep on my back, it sounds like I am choking to death. Are their exercises I can use to help? Special type of straps? I did a search about this, and I saw some mentioning about special straps, that distribute the bass's weight better. I would really like to keep using it, but right now it just sits in the corcer and gathers dust. Thanks!
