Designed for guitar, keyboards, bass, and more, the Operation Overlord from Electro-Harmonix is a stereo overdrive and distortion pedal. It utilizes three JFET gain stages to emulate the harmonically rich sound of a tube amp driven at varying degrees of level.

\r\n

\r\n\r\nOther goodies abound, such as a Boost mode for introducing an overdrive circuit before the JFET stages, selectable input levels by means of the onboard toggle switch, and an active three-band EQ for shaping the timbre of the resulting boost/overdrive. A dry/wet knob is also provided, suitable for dialing in dry signal and lending more definition to the notes of synths, electric basses, or guitars feeding already-overdriven amplifiers.

\r\n\r\nThis is a stereo pedal with full stereo routing, giving you independent distortion circuits for the left and right 1/4' I/O stages. You can operate this pedal in mono with a guitar by utilizing its left channel, drive a stereo keyboard through its boost/distortion circuits and feed different two amplifiers/mixer-input channels, or even use the pedal to split a mono source two different destinations. An Electro-Harmonix 9.6 VDC 200mA power supply is included with the pedal.
