A complete test of the Human Amp Driver pedal boosting the Engl Powerball (Version 1).
The Amp Driver makes the Powerball far more versatile and opens up all new tonal possibilities. The Amp Driver can be used to make a classic, plexi style classic rock and singing blues distortion on Channel 1, boost Channel 2 into a proper high gain monster and focus Channels 3 and 4, adding tightness and removing low end flub.
When paired with the Amp Driver amps like the Powerball now cover a much wider variety of genres and sounds.
