The first Gibson Ace Frehley Signature model was this Gibson Custom Shop Ace Frehley Les Paul Custom made from March to July 1997. Less than 300 were made in total, to a design based on Ace's 1970s cherry sunburst finished Les Paul Custom with three humbucking DiMarzio pick-ups. The Gibson specs for this model state two DiMarzio Super Distortion pickups (DP100) and one DiMarzio Dual Sound pickup (DP101). Some of these guitars were supplied with DiMarzio PAFs (DP103) perhaps due to difficulties supplying the DP101s and DP100s.
Other specifications included: AAA Flamed Maple top, Les Paul "Custom" style binding, Cherry Sunburst Finish, Custom Ace Frehley headstock veneer (of Ace in KISS makeup), Ebony fingerboard with lightning bolt inlays, 12th fret "Ace Frehley" pearl inlay, Custom Ace Frehley serial number hand inked on as ACE 001 to 300, Grover tuners with pearloid buttons, Gibson ABR-1 Bridge, Sterling Silver Engraved (Ace of Hearts) trussrod cover, switch plate and back plate.
This guitar came without a pickguard fitted - although Gibson supplied a pickguard in case you wanted to put it on later. The hard shell
Gibson Custom & Historic Shop case was customized with an Ace Frehley screen printed signature
There was also a Gibson USA production model Ace Frehley Signature Les Paul, made from August 1997 until January 2001, which was outwardly very similar to these Custom Shop versions - however the production model did not have the engraved sterling silver truss rod and control plate covers, the flame maple top was not to the same quality (AA vs AAA), they did not have pearloid tuner buttons and they did not have the hand inked serial numbers.
