“The Hi Volt is a mid- to high-gain dirt box, with a fully saturated
effect that is internally charge-pumped to 16VDC, and brandishes a high
headroom, custom-tuned 3-band active EQ. This high-voltage configuration
allows for very flexible and potent sonic possibilities, ranging from
blues to metal and everything in between.
With its generous low-end wallop, the Hi Volt creates amazing depth
and three-dimensional mass with an amp or rig of any size. Now your
compact combo amp can sound like a towering full stack, simply by
engaging the Hi Volt’s unique circuitry.
As you increase the Hi Volt’s “Bass” control, you can add warmth and
body to your tone without the signal getting loose or tubby. The Hi Volt
is a very tight effect and responds to rapidly changing playing
dynamics, just like your favorite tube amp would.
With the gain knob set at around 9 o’clock, you get a tight, British
clang that nails your favorite 70’s classic rock riffs. Set the gain at 1
o’clock for more saturation from signing lead tones to 90’s grunge
riffage. Setting the gain around 3 o’clock will deliver some of the most
brutal tones to ever come out of a stomp box.“
