This pedal is pretty standard fair for an overdrive. Three knobs: gain, tone and volume, and a stomp switch. Killer easy to use.
Distortion pedal, that's terribly easy to use because, like most dirt boxes, it has three knobs: volume, tone and gain. Not really breaking any new ground here, but completely acceptable and logical to use.
