The MXR Phase 45 is a hand-wired reissue of the rare, classic phaser pedal straight from the MXR Custom Shop. This little brother of the Phase 90 offers subtle, rich, two-stage analog phasing that adds depth and texture without dominating your tone. Operation couldn't be more idiot-proof, with a solitary speed knob being the MXR Phase 45 's only control. The top-shelf componentry includes hand-matches FET's, a Carling switch, a CTS pot, and Switchcraft jacks. The MXR Phase 45 operates at 9V DC.
