Dumble Steel String Singer

The Dumble Steel String Singer is one of the rarest and most coveted amplifiers ever built. Hand-wired by Alexander Howard Dumble in extremely limited numbers, each amp was custom-voiced for its owner. Stevie Ray Vaughan used a Steel String Singer alongside his Fender Vibroverbs to achieve his signature tone — a crystalline clean channel that could be pushed into rich, singing overdrive with extraordinary touch sensitivity. The amp's legendary transparent quality preserves every nuance of the player's dynamics while adding warmth and harmonic complexity. With fewer than 300 Dumbles ever made, they have become the holy grail of guitar amplification.
