Hey Yon,
Beautiful looking guitar! The S/N places it around 1995-1996. It has a gorgeous Silver Metallic which has the fine particulate in contrast to the Silver Sparkle of e.g. a
John Jorgenson Signature. A similar finish can be found on this
1989 ASAT shown on Grag Gagliano's website or this
ASAT III on my own website. But you see both still have a white enameled aluminum pickguard instead of the BWB triple ply plastic guard on yours. Another indicator your guitar is from the BBE-era is the absence of the
"by Leo Fender" script logo on the headstock. Since it has black powder-coated hardware, your model would be called an ASAT in the day, in contrast to the ASAT Special which has chrome hardware. The black hardware was discontinued in 1998 and has since only been seen on the 2009
C.L.F. Centennial ASAT and on some recent test mules (see CLF Research YouTube vids with Dave McLaren).
As far as the tuning machines go, they are legit. G&L was using both
Schaller and
Sperzel machines in those years. Which ones were used depended on inventory and availability.
BTW, your guitar already has an entry in the Registry.
Hope this helps,
- Jos
