If you're trying to mimic Stevie's number one you're better with a flatter radius, his strat had been refretted so many times that it had evolved to about a 12" radius. I did kind of a copy of Number One years ago out of a warmoth neck and body. The neck was probably closer to Stevies than the signature model because they offer a 1 3/4" nut and fender's is their standard size. I even set it up (With 13s which I play anyway, no hand trouble btw) with the measurements Dan Erlewine took off of #1 in the GPRG. The result? I hated it, except for the left handed trem. I now had the guitar in pieces waiting for a new neck (didn't like the SRV contour), humbuckers, and a new paint job.
