Tube Works was founded by B.K. Butler, known for designing the original Tube Driver pedals used by major touring and recording artists. The MosValve line was created to offer tube‑like dynamics using MOSFET technology, providing warmth and musicality without the maintenance demands of tube power amps.
Genz Benz later distributed Tube Works products, bringing their engineering oversight and reputation for rugged, gig‑ready amplification. Their involvement ensured consistent build quality and reliable performance across the MosValve series.
