The GB20 is a hollow body electric guitar model introduced by Ibanez in 1977. It is a signature model for American jazz guitarist George Benson. It is made in Japan.

The GB20 was Ibanez's first hollow body artist signature guitar along with it's smaller sibling, the GB10.

The GB20 features a large, single cutaway, full hollow body design with an arched spruce top with ƒ holes and multi-layer binding and an arched birdseye 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 pearl/acrylic and abalone split block position markers. Components include a single floating Ibanez GB special humbucking pickup at the neck 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.

The GB10 is a similar model with a smaller (yet thicker) body and two pickups.

The GB20 was discontinued after 1982.
