MXR 20th Anniversary Zakk Wylde Signature Phaser
MXR · pedal
The MXR ZW-90 Wylde Phase is Zakk Wylde's signature take on the Phase 90, offered here in a 20th Anniversary edition finish. It keeps the one-knob simplicity of the original: a single Speed control ranging from a slow, warm, liquid analogue sweep to a fast, fierce staccato pulse. The voicing is smooth and warm, thickening and animating the signal without adding harshness or overpowering the core tone, which is why it holds together under the heavy distortion Wylde plays it with. It is at its most distinctive on high-gain rhythm and lead work at slow speeds, where the sweep lends a swirling, vocal movement to sustained notes. It also works well on bass and keyboards. Powered by a 9V battery or a standard supply.
