Daredevil Pedals Knuckle Duster Overdrive True bypass, hand wired. Takes you from a boost to BIG overdrive to ripping distortion tones. Bright control helps dial it in for solos that cut, or tames that sharp high end from single coils. This is a giant sounding pedal, lots of output and attitude. Knuckle Duster sounds great with bass and keeps a natural amp overdrive feel without all the compression and mudddy low end.
