The JP20 is a hollow body electric guitar model introduced by Ibanez for 1982. It is a signature model for American jazz guitarist Joe Pass. It was made in Japan. The JP20 was the first and only signature guitar made for Pass by Ibanez.

The JP20 features a full-sized, single cutaway, full hollow body design with an arched spruce top with ƒ holes and multi-layer binding on maple back and sides mated to a set-in three-piece maple neck with a 22-fret ebony fingerboard with binding and pearl and abalone split block position markers. Components include a single Ibanez Super 58 humbucking pickup with a gold cover mounted in a black pickup ring between the neck and bridge; a height-adjustable ebony bridge with ebony tailpiece; a bone nut; a tortoise pickguard; Sure Grip knobs; and VelveTune tuning machines with pearloid acrylic buttons.

For 1983 the tuners were replaced with the new VelveTune II models and the Sure Grip II knobs were introduced. For 1985 the Smooth Tuner II machine heads were introduced. For 1988 the tuners were replaced with Gotoh SG38 models.

The JP20 was discontinued after 1990.
