The Morley Philosophy: Modern, Robust Optical Wah Designed for the Stage
This pedal follows the tradition of Morley Wahs known for their optical approach: instead of a mechanical potentiometer that can crackle over time, the sweep is managed by an optical system designed to remain smooth and silent. The addition of a custom inductor delivers the expected character of a musical Wah, while maintaining a consistent and reliable response for intensive use.
For Which Guitarists (and Styles)?
If you often switch between rhythms and solos, or want to move from clean to lead without touching the amp, the Volume + Boost combo quickly becomes indispensable. The Wah section suits funk and blues riffs (sharp attack, groove emphasis) as well as rock and metal genres (expressive sweep, ideal before distortion). In the studio, it's used both to shape a take and to automate volume swells "pedal-style," and live it secures level changes with immediate handling.

Questions frequently asked
Does the boost of the Morley Lerxst Power Wah Volume rise enough for a solo?
The adjustable boost delivers up to +20 dB via a dedicated potentiometer. This setting allows for an increase in level suitable for solo passages without altering the saturation setting.
Does the Wah use a mechanical potentiometer?
The sweep relies on an optical system, without a mechanical potentiometer that may cause crackling over time. A custom inductor contributes to the musical character and resonance of the effect.
Can it replace a volume pedal for gradual swells?
The Volume section enables level swells with the pedal and manages transitions between rhythm parts and solos. Foot activation engages the effect immediately.
What power supply is required for this Morley Wah pedal?
A 9 V mains power supply is required.
Is the built-in buffer useful on a pedalboard with long cables?
The built-in buffer helps preserve signal clarity and definition in a loaded pedal chain. It also helps maintain a stable presence with long cables. The metal enclosure measures 174 x 114 x 63.5 mm.
