THD UniValve

Introducing the THD UniValve™ Amplifier!

The new THD UniValve is a Single-Ended Class A amplifier head with a single output tube that can be switched at will among many octal-based power tubes, including 6L6, EL34, 6550, 7027, KT90, KT88, KT77 and KT66, for different tones without re-biasing the amp. Likewise, the two pre-amp tubes can be any combination of 12AX7, 12AT7, 12AU7, 12AY7 or 12AZ7. The UniValve delivers tones from smooth and clear to very aggressive overdrive. It is easily capable of driving a 4 x 12" cabinet, yet quite small and light. It has a built-in Hot Plate™ Power Attenuator that allows for full output distortion at almost any volume. And it don't cost as much as you might think.
