The GB30th is a hollow body electric guitar model introduced by Ibanez for 2008. It is a signature model for American jazz guitarist George Benson commemorating the 30th anniversary of his relationship with the brand. It was made in Japan.
The GB30th is based on Benson's original GB10 model, but has a unique gold foil finish inspired by the Japanese foil craft of garahuku and special fretboard inlays. It features a smallish, single cutaway, full hollow body design with a spruce top with ƒ holes and multi-layer binding and maple back and sides mated to a set-in three-piece maple neck with a large headstock and a 22-fret ebony fingerboard with binding and special pearl anniversary 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; and a tortoise pickguard.
