This is Guild's version of the Bigsby B-6 that has been in use since 1961. The gold version was used on the Duane Eddy-500, the pre-1967 Starfire VIs and special order X-500s. Left-handed units are very hard to find and even harder in 'gold'. This is a 'New Old Stock' unit that has some scratch marks caused by the way it was stored.
