The GB12 is a hollow body electric guitar model introduced by Ibanez in 1990. It is a signature model for American jazz guitarist George Benson. It is made in Japan by FujiGen.

The GB12 was released to commemorate the twelfth anniversary of the introduction of the first George Benson signature guitar, the GB10. The body of the GB12 is a half inch thicker than the GB10 and it has a special 12th anniversary headstock inlay.

The GB12 features a smallish, single cutaway, full hollow body design with a laminated flamed maple top with ƒ holes and multi-layer binding on flamed maple back and sides mated to a set-in three-piece maple and mahogany neck with a large headstock and a 22-fret ebony fingerboard with binding and pearl and abalone decorative position markers. Components include dual, floating Ibanez GB special humbucking pickups with individual volume and tone controls; a height-adjustable ebony bridge with special adjustable split trapeze tailpiece; a bone and brass nut; a flamed maple pickguard finished to match the body; Sure Grip II knobs; and Gotoh tuning machines. Each GB12 is numbered and personally autographed by Benson.

The GB12 was discontinued after 1992.
