Celebrate the 20th anniversary of the explosive collaboration between Dunlop and Zakk with the MXR Wylde Audio Phase. This pedal adds dimension and dynamics to Zakk's legendarily blazing solos and razor sharp leads—all with the twist of a single Rate knob. Take it from a slow grind to a jack hammering pulse, or use it as Zakk does, at the 9 o'clock position for a slow burning sweep. Jack your tone into another dimension with the MXR Wylde Audio Phase.
