The beaten and battered Tri-Sonic (nicknamed Grandpa) has a one-piece ash body that was originally routed for two Z-coil pickups—which were eventually implemented on the ASAT Z-3—and one of Leo’s prototype trems. The back of the guitar has a battery pocket (perhaps active electronics were in the works) and the beginnings of a B-Bender slot. Currie made a maple neck at G&L, but it broke during a gig at Al’s Bar in 1993 so he made the current maple neck—currently on its third refret—at Tak Hosono’s shop (Hosono now oversees the Ibanez Custom Shop). Other parts implemented on the guitar are CTS pots, nickel Kluson tuners, and a single-ply pickguard. Right now the guitar is loaded with three Amalfitano vintage-voiced alnico 2 singlecoils, and Currie says it plays and records better than any guitar he’s ever had or heard.
