The GB30 is a hollow body electric guitar model introduced by Ibanez in 1986. It is a signature model for American jazz guitarist George Benson. It was made in Japan.

The GB30 is a semi-hollow version of Benson's flagship GB10 full-hollow body model with which is shares a silhouette. It has a slightly smaller, thinner body with a solid maple center block and different neck, pickups, bridge and tailpiece than the GB10. In addition the pickup selector toggle is located on the lower horn.

The GB30 features a compact, single cutaway, semi-hollow body design with a maple top with ƒ holes and multi-layer binding on maple back and sides with a solid maple center block mated to a set-in maple neck with a large headstock and a 22-fret ebony fingerboard with binding and offset abalone dot position markers. Components include a pair of Ibanez Super 58 humbucking pickups with black covers and individual volume and tone controls; black plastic pickup rings; a face-mounted output jack; a Tune-o-matic style Gibraltar II bridge with a Quick Change II tailpiece; a bone nut; a black pickguard; Sure Grip II knobs and Ibanez Smooth Tuner II machineheads.

For 1988 the tuners were changed to Gotoh SG38.

The GB30 was discontinued after 1993.
