This is one trick little booster. We used 2 of our exclusive Farndurk Boost circuits and built them on to one circuit board. We then placed them in an A/B configuration. You can have it setup so that when you hit the footswitch, you A/B between the two independent boost circuits. Or, you can set it up so the footswitch toggles between one boost circuit (boost A) and True Bypass. How cool is that? It's all done with the little mode toggle switch. Place it UP (center LED on) and the pedal is a dual booster that A/B's between the two boosts. Place the center toggle DOWN (center LED off) and the Boosten now is a single channel boost that will True Bypass via the footswitch. Slick, yea?
