Angry Troll spoons up unhealthy amounts of volume on your guitar signal, to drive your amp crazy. Not only that, the pedal's ANGER control allows you to select 6 levels of gain, pushing the pedal's internal op-amp to give your riffs a pleasing crunch.
Bypass on the pedal is True Hardwire Relay. It can be powered by a 9V battery or a 9VDC adapter, and the current consumption is 7.7mA.
