The Supro Single Cone Resonator Guitar is a vintage-style resophonic acoustic guitar built around a traditional single-cone resonator design, delivering the distinctive projection, metallic character and fast attack associated with classic blues, folk and slide guitar playing. Produced under the historic Supro brand, these instruments were manufactured during the National and Valco eras and feature a resonator cone mounted within the body to mechanically amplify the strings' vibrations. The single-cone construction produces a direct, punchy response with strong midrange presence, making it particularly suited to fingerstyle, bottleneck slide and roots music applications.

Construction features a rosewood fingerboard, a mahogany neck and a metal body design. The resonator assembly is housed beneath a decorative metal coverplate, while the traditional round-neck configuration allows for both standard fretted playing and slide techniques. It comes equipped with sealed tuning machines, dot fingerboard inlays and a biscuit-style single-cone resonator system that contributes to its distinctive tonal character. 

As part of the historic Supro catalogue, the Single Cone Resonator Guitar represents an important chapter in American resonator guitar production. The design traces its roots to the resonator instruments developed during the early twentieth century, where increased volume and projection were required before widespread electric amplification. Its single-cone resonator construction provides the bright attack, focused response and resonant voice that continue to make vintage Supro resonator guitars sought after by players and collectors interested in traditional blues, folk and Americana instruments.
