whew! I read through all this stuff without comment. I still maintain that the 17 degree back angle of a Gibson headstock contributes to the awesome tone we expect from our Gibsons, and get. I still top wrap both my Gibson SGs, feeling that this MIGHT contribute to the awesome sustain that I get from both... and not caring much about nay sayers. I'm getting great tone, so I don't want to consider altering anything. That's my experience. To a Telecaster player, it's all meaningless. Telecasters sound awesome in spite of all that's been presented on this thread. I do own a Telecaster... it has a string through body, eliminating all concerns and/or hype from Tuna-matic users. My Tele has zero back angle on the headstock, but includes a pair of string trees which increase the pressure on the nut for the D, G, B and E strings. This is effective and contributes to the awesome Fender tone I get from my Tele. So it goes, eh? Cela, c'est com s'il va alors... I don't know any answers to this thread, but I do know what I like. And that includes Gibsons with a 17 degree back angle to the headstock, Epiphones with a 14 degree back angle, and Fenders with zero back angle but lubricated (by me) string trees which accomplish a similar effect. Rock on, comrades.
