Hello! Long-time browser of this site, first-time poster. I have a problem with this Geddy Lee Fender Jazz Bass I bought it a while ago, and love it. It weighs about 9+ pounds and is much heavier than my old fender p-bass. I'm not the biggest guy, I'm about 5'8 and 155 pounds. After a couple of months of using this bass, my shoulder started getting sore so I bought a wide leather strap, and that help for a while. Now it's getting worse and i think i tweaked a nerve the other day. My shoulder had sharp pains and i could barely lift my arm without it hurting. I usually have to sit on a stool during band practice and it kinda sucks. I heard that Comfort straps are nice but at this point, I don't know if it's going to be enough. so. Can anyone recommend a light bass that's good for funk/rock? Or if you had any suggestions about what I should do, I'm all ears!
