Already in the 1980s, John Jorgenson, later of The Hellecasters fame, was not only a G&L ASAT endorser but also provider of some exciting new ideas. One was to add a dummy coil underneath a Jumbo Magnetic Field Design (MFD) single-coil pickup for hum cancellation, intended to be the defining feature of the John Jorgenson Signature model. But it was not to be, much to the chagrin of Mr Jorgenson. Instead, one got an ASAT with swamp ash body, John favorite Silver Flake finish done by Marty Bell in Texas, Saddle-Lock bridge, 2 standard Jumbo MFD pickups, and usual ASAT wiring harness (3-position pickup selector, volume, tone). This particular guitar has the early transparent pickguard which was soon replaced by a laminate sparkle pickguard on later Signatures. Otherwise this model has a gloss finished hard-rock maple Bi-Cut neck with the more common rosewood fingerboard having a 7½” radius. And although one finds John’s signature on the headstock, the endorsement deal was terminated with about 190 Signatures having been built. Hence this model is a Rarebird in the Guitars by Leo Registry.

For more info, consult Greg Gagliano’s ggjaguar.com website for an exemplar with a rosewood fingerboard as well as one with a (rare) maple fingerboard, both with a laminate pickguard. Note that the indicated finish in the Registry, on Greg’s site, as well as here is marked as Silver Flake in which large flakes are used. Nowadays, that finish goes by the name Silver Metal Flake.
