The Dual Tone was part of a series of solidbodies produced by Supro starting in the late '50s. These guitars were also distributed under the Airline brand name. Many Supro designs were made from either wood or "Res-o-glass" material. Those made from Reso-o-glass are usually more desirable for collectors.
