Excellent! THD Univalve Class-A15-watt Tube Amp Head - $579 (Alpharetta/Johns Creek)
QR Code Link to This Post
One of the more versatile and useful small heads of the last few decades, the THD UniValve is a single-ended amp that will take any octal-base output tube without rebiasing which, coupled with the integral finely-adjustable power attenuator, gives it an incredible array of overdrive varieties. Volume, bass, treble, and “attitude” controls, power attenuation knob, noise reduction switch, lo/hi voltage control, and full/half power switch give unparalleled flexibility at home, in the studio, or in a small club. Fender or a Boogie? Install a 6L6. Feeling Marshall or Orange? Grab an El34. Tons of fun in a very small and portable package. This one is in very good cosmetic, structural, and electronic condition. Designed by Andy Marshall, made in Seattle, Washington, USA.
The controls are the traditional Volume, Treble and Bass controls along with what we call an "Attitude" control. The Attitude control is not a Presence control, as the amplifier has no negative feedback from the output transformer back into the driver stage. The Attitude control determines how the driver stage responds to signal and how it drives the power tube. There is also a built-in THD Hot Plate power attenuator that lets you have full output distortion at any volume level. The Hot Plate has its own hard-bypass switch on the front panel, which completely removes it from the circuit for Full-Power playing into a speaker.
Open to possible trade for guitar.
