Re: Help! Is this an FGM100 or 540SLTD?
The first Gambale production included this black one with the silver sharks, as evidenced by the rolling eyes emoticon and the link above. There were no S series guitars in 1990 or 1991 that had the AANJ, besides the 540SCT6, and that had the original AANJ with the long tenon under the neck pickup, tee nuts, and oval inlays. So you can't even say that a neck swap or modification was done to this guitar to produce such a forgery. It's clearly the FGM100BK, and with a 1990 serial number, undoubtedly one of the first batch ever produced! It's a great find!
