Well, I don't have an SG but I figured you guys would be pretty experienced in this topic. I've got an ES-339 which I think is on the lighter side at ~7 lbs. It neck dives a little bit which isn't a huge problem for me since I'm used to it, my last guitar did the same, but eliminating it entirely seems to be within reach so I figured I'd try. The guitar came with Grover milk bottle tuners which I've read are quite heavy in terms of tuners. Today I pulled off the six buttons (and only the buttons) and with all six buttons removed, the guitar has what I would consider to be perfect balance. Even putting one button back on tips it back into slight neck-heaviness. Does anyone know how much each button/screw combo weighs? Could I find a set of buttons that weigh the same as a single Grover button or would replacing them with kluson style tuners entirely be a better bet? I think this guitar is absolutely beautiful and it sounds great, I really don't want to get rid of it over neck-heaviness in case somebody was gonna just suggest that instead.
