I just bought a Fender Jaguar bass and love everything about it...except for the slight neck dive. I thought adding small weights in the electronics cavity would help, but the cavity is too small for that. Would adding a replacement bridge give me the added ounces to balance this thing out? I've also heard of replacing the machine heads with lighter ones, but I am having a hard time figuring out what product would be a 1 to 1 tradeout for the ambiguously-named "vintage style" machines that come stock. If possible, could you provide brand names and/or models when making suggestions, since I find some of the websites for these products confusing or unclear when I surf them myself?
