Slap your amplifier with the Electro Harmonix OD Glove overdrive pedal for guitar tone that's biting and defined. There's no tonal mud here - MOSFET semi-conductors give the OD Glove a harmonically rich sound with a surprisingly wide distortion range. Even when you've got the gain dimed and the mid-boost switch engaged, you can clean your tone up to a whisper with just your guitar's volume knob. And with an internal 9V/18V switch, you can even adjust the feel of the electro-harmonix OD Glove overdrive pedal. The Electro Harmonix OD Glove provides a rich, overtone laden sound that doesn’t get muddy. Responsive controls that take you from sparkling, clean boost through brown crunch and all the way to thick, saturated hi-gain. Advanced features like Tone Shift and selectable 9 or 18V internal voltage for surgical sound sculpting. • Versatile MOSFET overdrive/distortion • Tone Shift switch • Selectable 9V or 18V internal voltage • True bypass • Tough, compact die-cast chassis • 9V battery included
