I have a '92 Fender Jazz MIM neck that's attached to a very light body. Formula for neck dive. The tuners are original (I believe) "Licensed by Schaller" clover leaf.I believe the holes in my peghead are 11/16" (0.6875 inches). Warmoth sells Schaller lightweight tuners but the shaft diameter is 0.67 inches. The Warmoth rep told me they wouldn't fit. Checking the Stew-Mac website, their lightweight tuners (Gotoh and Hipshot) need 9/16" holes. The Hipshot website has lightweight tuners with 1/2" and 3/8" in the titles, but I have no idea what that means. What to do? Where can I get some lightweight tuners that will fit?
