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."
