Morley MTPWB Cliff Burton Power Wah Boost Pedal - Super Chrome Plus

As the original bassist for Metallica, Cliff Burton helped define some of heavy metal’s most recognizable bass tones through his use of Morley wah pedals and aggressive front-end boost. The MTPWB Morley Cliff Burton Power Wah Boost pedal recreates the character of the 1970s Power Wah Boost Burton used during the band’s formative years, delivering the original wah sweep alongside up to 40 dB of boost in a modern pedalboard-friendly format. Separate wah and boost footswitches, electro-optical wah operation, chrome hardware, a glow-in-the-dark treadle grip, LED indication and a cold-rolled steel housing combine vintage-inspired design with contemporary reliability. Suitable for bass, guitar and keyboards, this signature pedal captures a key element of Burton’s legendary sound while providing expressive filtering and powerful signal enhancement for modern players.

Vintage Tel-Ray Tone Recreated for Modern Rigs

Developed as part of Morley’s Tel-Ray Revival series and approved by the Burton Family Foundation, the Cliff Burton Power Wah Boost is designed to recreate the tone and sweep of the original 1970s Power Wah Boost. While the sound and feel remain faithful to the vintage unit, the enclosure has been scaled to fit more comfortably on modern pedalboards. The electro-optical wah design eliminates traditional pots, helping maintain a smooth, consistent sweep while reducing mechanical wear and unwanted noise over time.

Independent Wah and Boost Performance Control

Separate wah and boost footswitches allow each effect to be used independently or combined for greater tonal flexibility. Engage the wah for vocal-like filter sweeps, activate the boost to push the front end of an amp or signal chain, or stack both effects together for more aggressive textures and increased saturation. A dedicated boost intensity control provides up to 40 dB of boost, making it easy to dial in anything from subtle enhancement to the powerful signal lift associated with Burton’s iconic sound.

Chrome Styling and Roadworthy Construction

The pedal’s chrome base and treadle, retro Tel-Ray-inspired details and elevated chassis pay tribute to Morley’s classic designs while remaining practical for modern performance environments. A glow-in-the-dark treadle grip improves visibility on dark stages, while LED indication provides quick status confirmation. The cold-rolled steel housing and quick-clip battery door complete a durable design built for regular rehearsal, recording and live use.

A Signature Wah Boost Inspired by a Bass Legend

Whether you're pursuing Burton-inspired bass tones, adding expressive wah textures to guitar parts or pushing keyboards into more aggressive sonic territory, the Cliff Burton Power Wah Boost offers a distinctive combination of vintage character and modern functionality. From the aggressive bass work heard on Kill 'Em All and Ride the Lightning to the melodic lead passages that helped make Master of Puppets a metal landmark, Burton's use of Morley wah pedals was a key ingredient of Metallica's sound. Recreated from one of Morley's most iconic designs, the Morley MTPWB Cliff Burton Power Wah Boost pedal delivers the unmistakable wah-and-boost experience that helped shape a generation of heavy music.
