Bi-Valve 30 30W Class A Tube Amp Head

The BiValve-30 amplifier head from THD is the big brother to THD's popular UniValve model, but with one major difference: dual output tubes. Both the output tubes and preamp tubes give you free reign on endless combinations to experiment with. The BiValve-30 delivers tones from smooth and clear to very aggressive overdrive, like the UniValve, but with more power and a much more compliant output transformer which means richer, thicker lows. It's easily capable of driving a 4x12" cabinet, yet light and easy to handle unlike many other amp heads. It's built-in Hot Plate power attenuator allows for full output distortion at almost any volume, and the unique combination of THD's touch-sensitive input circuit and the wonderfully active and reactive tone control make for a front-end that really responds to subtle and not-so-subtle changes in the signal.
