A tone-tweaker's dream head, now designed to sit comfortably on a 2x12" speaker cabinet.
THD BiValve-30 30W Class A Amplifier Head
The THD BiValve-30 30W Class A Amplifier Head is a pure Class A design with 2 output tubes wired in parallel and combined through a special output transformer to deliver up to 30W. It accepts almost any type of output or preamp tube without bias adjustment-even in combination-for an astonishingly wide range of tone available for nearly any style of guitar playing. The standard of construction is absolutely top-class, as you would expect for any handmade amplifier.
Inside, you'll find large transformers and hi-fi style internal baffle plates to cut down on hum, as well as the tube sockets. On its front panel is a pair of input jacks labeled More and Less, followed by a Cut switch (high-cut filter), Volume, Treble, Bass, and Attitude (driver tube response control). In the center is a light bulb that glows as the amp distorts with a small switch to turn it off, a control for the built-in Hot Plate (output attenuator), and a defeat switch for the Hot Plate.
Check the drop-down menu to the right to select colors and/or other options.
