Features that are included with the BiValve.
The BiValve has all the features of the UniValve and more! Producing as much as 30 watts, the BiValve 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. The BiValve could be your ultimate club gigging and recording amplifier.

The THD BiValve has a couple of notable features absent from it's little brother, the UniValve. An Effects loop and the Cut Switch. The Effects Loop allows you to patch effects into the BiValve post preamp. This feature is great for using delays, reverbs, additional eq, or any other effects that you want to run post the preamp. The Cut Switch cuts some high frequencies off for a warmer and smoother sound.

The ability of the THD BiValve to mix and match not only preamp tubes, but power tubes as well, gives it sonic options no other tube amplifier can match. In recording situations this feature alone makes the BiValve a must have for any serious tone maven! Throw out your fakey modeling boxes and get with some real tube tone folks! "But I need to record late at night without upsetting my family and neighbors" you say? You can disconnect your speaker cabinet from the BiValve or the UniValve safely for silent recording.

When there is no speaker plugged into the speaker jack, the amp uses its own built-in dummy load so no damage will occur, and to allow the silent use of the amp for direct recording purposes when miking a cabinet is not practical. With the speaker safely disconnected you may run directly out of the Line Out into a speaker simulator, like the Palmer or the Voodoo Labs CabTone, or run it direct without simulation. You will get a better result on overdrive tones with a speaker simulator, however. Direct out sounds amazing on cleaner tones, and it absolutely smokes for recording bass direct as well. Nails a vintage B-15 or SVT type tone direct to tape or DAW. Slap some headphones on and track real deal, fat tube tones directly! Plug guitars, basses, harmonicas, keyboards or whatever though it when recording. How cool is that? You need one of these killer amps!!
