Gongrats from a fellow McCarty owner! Yours is an earlier one, mine is an -02. And a killer guitar it is.
I've since replaced the frets (just been played to death), the pickups and modified the wiring. The original pickups didn't work for me on that guitar eventually (although I knew what I had in my hands the second I struck that first chord on this guitar), now it has a CS set . I also installed a treble bleed, so that the high end stays there when the volume is turned down.
