The Jet Star bass was one of the most unusual guitars of the 1960s, and probably of all time. With its Dali-esque 'melting' body and unusual headstock. This short-scale (30.5 inch) bass was featured in the 1966 Guild catalogue (see below) along with its companion guitar, the Guild Thunderbird S-200.
The Guild Jet-Star bass was described as follows in the 1968 Guild catalog
A solid body bass inspired by the lines of the Guild Thunderbird. Comfortable to hold, easy to control, as responsive as a lead guitar. Body is 13 1/4" wide, 19 1/4" long, 1 9/16" deep. Has a specially designed bass neck reinforced by an adjustable steel rod. Lightning-action rosewood fingerboard has a 30 1/2" scale and 10 inlaid position dots. Equipped with Guild's Anti-Hum Pick-Up adapted especially for bass. Functioning on the humbucking principle, it is hypersensitive to the complete range of string vibrations while filtering out all hum and other interference. Has separate tone and volume controls, two hand rests, and fine quality strings. <
Early examples (1964-65) were equipped with a single Hagstrom Bisonic pickup, changing to a single coil 'Mickey Mouse' style pickup in 1966. The unusual 2x2 headstock was also remodelled at this time, to a single sided Gibson Thunderbird style headstock. It still looked cool, but lost some of its originality in the process.
