MXR WA90 Wylde Audio Phase

The MXR WA90 Wylde Audio Phase marks 20 years of collaboration between Dunlop and Zakk Wylde. It adds dimension and dynamics to solos and leads with the twist of a single knob.

Take it from a slow grind to a jackhammering pulse — or use it as Zakk does, with the knob at 9 o’clock for a slow-burning sweep.

• Type: analogue phaser
• Single Speed knob controlling the effect rate
• Hardwire bypass for an uncoloured signal when the effect is off
• Input impedance: 1 MΩ — output: 10 kΩ
