One of Guild's more well-known solidbody guitars, the S-100 premiered in 1970 after the discontinuation of the Polara, which also used the S-100 model number. The S-100 was shaped very similar to the Gibson SG, but with asymmetrical horns. Its pickups were very large humbuckers controllable by four knobs and three-way switch. A phase switch was added to the model in 1972.

Between 1974 and 1977, Guild produced a version of this guitar with a carved acorn and oak leaf pattern in the front. The same design was used on the JS II bass as well.
