OVERVIEWGet more bang for your buck with this 30W menace from THD.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.FEATURESTHD BiValve-30 30W Class A Amplifier Head30W Class A amplifierSingle channelHand builtAccepts almost any preamp and power tubes in any combinationShips with 3 - 12AX7s (preamp) and 2 EL34s (power amp)More and Less inputsVolume, Treble, Bass, and Attitude knobsWon Guitarist Choice award from Guitarist MagazineVerdictThe BiValve delivers totally on theUniValve’s promise of more to come,and the result is one of the best playingexperiences any guitarist could hopefor.
