Hi everybody, I'm hoping to hear experienced advice. I'm thinking again about finding an SG, and I'm also considering using it as a platform for a Bigsby installation. I've been thinking about the SG Special P-90's from Gibson and Epiphone. Things being what they are these days, I'm probably going to buy one sight-unseen, except for photos and conversation. I have a few questions about it that maybe you know something about - Neck Dive. I hate it, I've payed guitars that do that and I hated it. So I ask, in your experience is there an overall weight that would make you feel relatively assured that the guitar won't neck-dive? I have a theory that a larger-than-normal proportion of used SG's have a neck-dive problem as their owners unload them, but it's just a guess. - Stop-tail and a future Bigsby installation. The SG Special P-90's by both Gibson and Epiphone have caught my eye, I don't have a P-90 equipped guitar now and want one. I'm assuming a B5 is the "one" for an SG but I'd like to avoid drilling into the guitar if I can avoid it. Would a B7 with a Vibramate work just as well? I've been eyeing the Towner system also, but since that's out of reach with a stop-tail like an SG Special I think I'm limited to a Bigsby with a build-in roller in front. - Bridge options. What options are there for a stop-tail bridge replacement that works well with a Bigsby? Well, that's all I can think of. What am I missing? I appreciate your help! Thanks.
