2000s THD UniValve

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.
