The AS400 is a hollow body electric guitar model introduced by Ibanez for 1980. It was made in Japan by FujiGen.
The AS400 features a semi-hollow, double cutaway body design with neck-through-body construction. It has a mahogany and maple neck mated to an arched maple top with ƒ holes and ivory multi-binding on maple back and sides with a 22-fret ebony fingerboard with ivory binding and pearl and abalone split block position markers. Components include a pair of Ibanez Super 70-A humbucking pickups with gold covers and individual volume and tone controls and a Tri-sound switch for the neck, black pickup rings, a Tune-o-matic style ST bridge, a Quik Change tailpiece, a bone nut, a tortoise shell pickguard, Sure Grip knobs, and VelveTune tuning machines with ivory buttons.
The AS200 is a similar model with a set-in neck and ivory pickup rings.
The AS400 was offered for only one year. The neck-through construction, which is very rare (perhaps unique) among Ibanez hollow-body guitars, combined with the limited production run combine to make this one of the most ardently sought after semi-hollow guitars among Ibanez collectors.
