Guitar effect pedal. This pedal combines the burly, buttery tones and amp-clobbering gain of the Red Llama Overdrive with a frequency doubler that creates an octave-up effect that will take you all the way from eerie ring modulator style effects to downright massive octave fuzz. In addition to the original Volume and Drive controls, the MkII comes with a Hi-Cut control so that you can shape and season the sonic wizardry to your own taste. Want to sound like a sitar? Just switch to your bridge pickup and pluck away at your strings right where they come off your bridge. Dynamic and touch-sensitive, the Purple Platypus Octidriver MkII is packed with symphonic potential.
