THD Flexi-50 amplifier

THD is thrilled to announce the arrival of their new Flexi-50 amplifier head. The Flexi-50 is a precision hand-built 50-watt Class-AB amplifier with footswitchable overdrive/boost, foot-switchable master volume control and the ability to use almost any preamp and power tubes in any combination.

How is the Flexi-50 diff erent? First off , it is a single-channel amplifier, but one that can be switched and blended among a number of diff erent sounding and different feeling voices. The changes can come from a number of methods including foot-switching a preset boost level with its own, dedicated tone control that allows you to make your boosted sound darker than the clean sound, brighter, or anywhere in between.

THD BiValve-30 amplifier

The big brother of the THD UniValve, the BiValve-30 is a Single-Ended Class-A amplifier head with dual output tubes that can be switched at will among any octal-based power tubes, including 6L6, EL-34, 6550, 6CA7. 6V6, 6K6, KT-90, KT-88, KT-77 and KT-66, for different tones without re-biasing the amp. The two output tubes do not need to be matched in any way—you are free to experiment with any combination you want! Likewise, the two preamp tubes can be any combination of 12AX7, 12AT7, 12AU7, 12AY7 or 12AZ7.

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 for thicker lows. It is easily capable of driving a 4x12" cabinet, yet quite small and relatively light. Finally, it has a built-in Hot Plate® Power Attenuator that allows for full output distortion at almost any volume. The unique combination of our touch-sensitive input circuit and the wonderfully active and reactive tone control section (that we slaved a year
to perfect) make for a front-end that really responds to subtle and not-so-subtle changes in the signal being fed into the amplifier either by the guitar or any effect that may be between the guitar and the amplifier.
