Eastwood's tribute to the SUPRO® Dual Tone. SUPRO® Guitars were made in the USA from 1958-68 by VALCO and sold through Montgomery Ward. VALCO also made National and AIRLINE brands. Today they are played by people like The Cure, Calexico, Raconteurs and White Stripes. This is our DLX version of the Twin Tone, which includes an installed B-50 Bigsby.
