The factory already had a CNC program for Special FM guitars. The CNC didn't care if it had a Maple top or just plain Mahogany . There may have been a setting for cutting speed. We all know with Hamers, even if it was not on the price list that year many variants got made. It could just have been a dealer tell a sales rep. I wish those specials came with Humbuckers instead of P-90's, ya, we can do that... I've seen a hand full of 90's era Specials with stock Humbuckers.
