Whether you’re tearing through a blazing solo or delivering razor-sharp leads, the WA90 promises to elevate your performance to new heights.

What truly sets the MXR Wylde Audio Phase apart is its remarkable simplicity and efficiency. Governed by a single, intuitive Rate (or SPEED) knob, players can seamlessly navigate through a wide spectrum of phasing effects. Rotate it counterclockwise for a languid, dreamy phase, reminiscent of Zakk’s preferred 9 o’clock setting, offering a slow, mesmerizing sweep. Crank it up in the opposite direction, and you’re in for a jack-hammering pulse, ensuring your solos cut through with vibrancy and vigor.

For those concerned about connectivity, the WA90 has got you covered. Simply link your guitar to its INPUT jack, connect its OUTPUT to your amplifier, and you’re set for an electrifying performance. Powering the pedal is equally straightforward. Whether you prefer a 9-volt battery, a Dunlop ECB003 AC adapter, or even an MXR Brick Series power supply, the Wylde Audio Phase is designed for versatility and convenience.

With an impressive input impedance of 1 MΩ and an output impedance of 10 kΩ, the pedal ensures minimal noise interference, boasting a noise floor less than -96 dBV. Furthermore, its hardwire bypass functionality guarantees that your signal remains pure and untouched when the effect is disengaged. Consuming a mere 5 mA of current and operating at 9 volts DC, this pedal is as efficient as it is powerful.

In conclusion, the MXR WA90 Wylde Audio Phase is not just a guitar pedal; it’s a celebration of musical heritage, precision engineering, and sonic innovation. Designed for both budding guitarists and seasoned professionals, this pedal is your ticket to capturing the essence of one of rock’s most iconic tones.
