The AX40 is an Axstar series solid body electric guitar model introduced by Ibanez in 1985. It was made in Japan.
The AX40 has a swoopy, pointy, X-style basswood body bolted to a maple neck with a 22-fret rosewood fingerboard with dot position markers. Components include a pair of Ibanez humbucking pickups, an OGE1086TBR tremolo system with a string lock behind the nut and Smooth Tuner II machine heads. The neck and headstock are painted black.
The AX48 is a version with a middle single coil pickup. The AX45 is a similar model with a humbucker/single/single pickup configuration. The AX30 is a similar model with a different tremolo system which doesn't employ a locking nut.
The AX40 was discontinued after 1985 in favor of a new line of headless Axstar models introduced for 1986.
