Alright, so I've got a jazz bass that I built a few years ago. It's a great bass, with good tone, and looks really sharp, if you ask me, but frankly, it's just too heavy for me. I have a back problem, even at my young age of 23, so as nice as the bass is, it simply never leaves the case. I replaced the tuners with Hipshot Ultralights, made a few other minor modifications (contoured the body a little, replaced the neck plate with neck ferrules, replaced the bridge, converted to string-through...), and got a nice, soft, wide Taylor strap, but it's still too heavy. So here's what I'm thinking... I know the idea of planing 1/4" off the top and hollowing out the body has been beaten to death here, so I think that's what I'll do. I'm going to use spruce for the top, since it's a tried and true top wood that's also very lightweight. Oh, and don't worry. The finish is acrylic lacquer -- very hard. I'm not going to worry about bracing, since this is just going to be semi-hollow. I don't think it will need bracing. Question, though. Since it's going to be refinished a solid color, would there be a problem if, say, I had to rotate the top 30 degrees in order to cover the entire body? I know that if this were an acoustic with a transparent finish, that would be totally unacceptable, but I figure no one is going to see the glue line or the grain or anything. The body is 13.5" wide, and so is the top, so I doubt I'll have to, but just in case. EDIT: Okay, my mistake. The body is 13" wide and the top wood is 13.5" wide, so there's shouldn't be a problem.
