Just thought to say that my recent purchase of a 2015 McCarty was better than I could hope for; the tone and weight of the guitar surpasses my expectations. The only upgrade that the guitar could conceivably receive are some bridge stud replacements. The current ones seems to have been adjusted rather roughly, leaving some chewed up looking edges on the stud slots. (See below) I realize that John Mann has what I need for replacements. IIRC, what's in the guitar currently are polished nickel bridge studs. What tools should one use when installing the bridge studs? My feeling is that a ½-inch wide screwdriver will not be adequate for the job, since this is the same width as the chewed-up markings on the studs.
