PROVIDENCE SOV-2 STAMPEDE OD overdriveThe Providence SOV 2 Stampede OD pedal is designed to deliver natural overdrive without obscuring the inherent characteristics and tone of the guitar being used. It features a special bipolar power supply that powers the internal circuitry with 15 volts, providing more than three times the dynamic range of conventional 9 volt powered overdrives. For singing lead tones and solid, chunky rhythms, there's nothing like the SOV 2 Stampede OD.
