The ID90 is a solid body electric guitar model introduced by Ibanez in 1989. It was part of the short-lived Dyuke series which was offered only in Japan.
The Dyuke line features a body style reminiscent of the Fender Stratocaster. It's an offset, double-cutaway shape with horns that are a bit shorter and wider than those of the RG body.
The ID90 features an ash body with binding on the top bolted to a maple neck with a bubinga stripe and a 24-fret bound ebony fingerboard with sharktooth position markers. Components include Ibanez Lo-Z active pickups with a humbucker and the bridge and a single-coil at the neck, an Edge double locking tremolo bridge with a locking nut and Gotoh tuning machines. It has a small black pickguard mounted below the pickups.
Controls consist of a master volume and two other knobs which control separate EQs for treble (±20 dB @ 6 KHz) and bass (±13 dB @ 500 KHz).
The entire Dyuke line, including the ID90, was discontinued after just one year of production.
