I'm thinking about getting one of these. I have a Squier Pro Tone Strat and it is not listed anywhere on the Callaham site, so I'm not sure as to which to get. I emailed them and was told to measure the string spacing (center of e to center of E) as well as to measure the distance from the centers of the two outside pivot screws. I did this and came up with 56 mm for both measurements (I'm not good with measuring inches). If my conversions are correct, it comes out to 2.2047244 inch inches. This is different from the two sizes that he offers (2 1/16" and 2 7/32"). Is it the vintage repro then? I doesn't measure up exactly, but then again, I didn't use the most exact methods. The guitar has a vintage 6 point bridge, by the way. Also, is it worth the $60 or whatever? Is there a noticable difference?
