The AM400 is a hollow body electric guitar model introduced by Ibanez for 1988. It was made in Japan by Terada as part of the Artstar series.
The AM400 features a compact, semi-hollow, double cutaway body design with a special rounded back and sculpted neck heel. It has an arched, birdseye maple top with a single ƒ hole and ivory multi-binding on mahogany back and sides with a maple center block mated to a set-in mahogany and maple neck with a 22-fret ebony fingerboard with ivory binding and pearl and abalone split block position markers. Components include a pair of Ibanez Super 58 humbucking pickups with gold covers mounted in ivory plastic pickup rings, a Tune-o-matic style Gibraltar II bridge, a Quik Change II tailpiece, a bone nut, Sure Grip II knobs, and Gotoh tuning machines with ivory buttons.
The AM300 has a similar body shape but with a maple top and basswood back and with different components.
