The Lerxst ATWAS Wah/Volume is a dual-function guitar pedal that pairs a responsive optical wah circuit with a smooth treadle-based volume control, built to Alex Lifeson’s exact specifications.

Developed under his Lerxst Electronics brand, the ATWAS delivers the sweep and midrange push Lifeson used throughout Rush’s later tours and recordings.

History & Background

Lerxst Electronics Origins

Alex Lifeson launched Lerxst Electronics in the early 2000s to produce signature gear that met his touring and studio demands after decades with Rush.

ATWAS Development

The ATWAS (A Tribute to Walter) combined the wah and volume functions Lifeson had previously achieved with separate pedals into one road-ready unit, first appearing in his live rig around 2010.

Notable Use

Lifeson's primary use of the ATWAS is documented on Rush’s Time Machine and R40 tours, where it handled both expressive wah leads and precise volume swells in songs such as “Limelight” and “The Spirit of Radio.”

🎯 Buyer's Guide

Check the treadle action and optical sensor response on any used unit, as the internal LED and photoresistor assembly can drift with age and heavy stage use.

New ATWAS pedals typically sell between $250 and $320, while well-maintained used examples from the first production runs command $180–$240 depending on condition and original packaging.

Confirm the version—early models feature a black chassis with silver lettering, while later runs added true-bypass switching and an external power jack.
