The AT100 is a solid body electric guitar introduced by Ibanez in 1999. It is a signature model of American guitarist Andy Timmons. It was the first signature model Ibanez made for Timmons.
The RG body shape is used for the AT100 but in terms of specifications it resembles a Fender Stratocaster more than a typical RG. It features an alder body bolted to a maple neck with a 22-fret maple fingerboard with black dot position markers. Components include a Wilkinson Gotoh VSVG traditional 6-screw synchronized tremolo bridge (with the middle two screws omitted), DiMarzio pickups with a signature humbucker at the bridge and two single coil sized Cruiser rail humbuckers in middle and neck positions and Sperzel locking tuning machines.
The AT100 was produced only in 1999 and in very limited quantities; perhaps as few as 175 example were produced, most of which were sold in Japan.[1] A reissue of this model known as the AT100CL was released in 2009.
