The AH20 is an solid body electric guitar model introduced by Ibanez in 1986. It was a signature model for British jazz fusion guitarist Allan Holdsworth (06 August 1946 – 15 April 2017).
The AH20 features a double-cutaway Roadstar II shaped basswood body with a tone chamber routed beneath the pickups bolted to a maple neck with a 25½" scale and a 17" radius 22-fret ebony fingerboard with dot position markers. Components include dual custom-made humbucking pickups mounted in a black pickguard, a specially configured Powerocker tremolo with a short 150mm tremolo arm, Tek Grip knobs and Smooth Tuner II machine heads. The headstock features a special spider logo which was designed by Holdsworth.
The AH10 is a similar model with a single humbucker.
