This is a double booster. Essentially you are looking at 2 Angry Inch circuits cascaded in 1 box. Each circuit has the essential same boost characteristics as the Angry Inch. But there's more. It's also an OD box... The cascading is where the fun begins. Use boost #1 to really slam the second one into overdrive. This gives a very smooth tweakable overdrive as a result. You can also use the pedal to set 4 independent levels using the 2 independant boost controls and the master volume.
Controls: Gain 1 - Volume - Gain 2
Power: Operates on a standard 9V (negative center) power supply. Can be used with a 9V battery.
