Morley Mark Tremonti Power Wah

The Morley Mark Tremonti Power Wah is a signature wah pedal from Morley, built to the specifications of Mark Tremonti, the guitarist known for his work with Creed and now Alter Bridge¹. It is a switchless wah with a built-in boost: the Wah Boost control gives up to 20 decibels of extra punch, and it activates together with the wah itself². Morley says Tremonti's signature wah has been his right-hand companion on stage for over two decades².

What sets it apart from a vintage-style wah is its voicing. MusicRadar's review team found the sweep is narrower than a vintage-style wah, eliminating the scratchiest part of the high end, giving the pedal a distinctly modern character¹. Morley describes the wah sweep as carefully tweaked to Mark's preferred settings².

A modern-voiced wah with a narrower sweep

The core of the pedal is a wah filter tuned to Tremonti's taste. Morley states the sweep was "carefully tweaked to Mark's preferred settings"², and the press agrees on the result: MusicRadar found the basic tonality at zero boost has a distinctly modern voicing, with a sweep narrower than a vintage-style wah that eliminates the scratchiest part of the high end¹. For a player, that means the pedal skips the harsh upper region where some wahs get thin and raspy, and concentrates its sweep where a modern lead tone lives.

Tremonti himself often uses his wah for solos, as guitar.com's reviewer noted⁵, and Morley's history page says the Power Wah went on to be another great seller and a favorite of metal guitarists⁶. The pedal sits in Morley's wider signature wah family alongside models like the Morley Bad Horsie Wah and the Morley George Lynch Dragon 2, each with its own tuned sweep.

The Wah Boost control

There is only one control knob on the pedal: Wah Boost³. It adds a bit of punch to your signal once the wah is engaged, up to +20dB³. Morley says the boost was set per Mark's specifications and activates with the switchless wah, so it is not a separate always-on boost, it rides along with the effect².

MusicRadar found the on-board boost brings in a raucous 20dB of extra gain, more than enough to get a solo noticed in a dense mix, and noted the rotary control can be manipulated on the fly with a foot¹. That last point matters on stage: the boost level can be re-set mid-song with a foot instead of bending over.

Electro-optical switchless design

The Tremonti wah is one of the few wahs without a clickable on/off switch: it automatically shuts itself off when you take your foot off the treadle³. Because the Power Wah uses an electro-optical switchless design, the filter is not engaged until you rock the pedal forward¹. In practice, a player steps on it to wah and steps off to play clean, with no toe-click timing to worry about.

The design also means there are no pots to wear out, which is Morley's famous electro-optical selling point². Instead of a mechanical potentiometer sweeping the filter, light and a light-sensitive element do the job, removing the component that traditionally gets scratchy with age. The pedal also carries a Clear-Tone buffer circuit³, and buffering is part of how Tremonti uses it: Morley notes his rig can run upwards of 180 ft of cable, and by having two to three of his signature Morley wahs in the chain, the buffers help preserve his tone, since he does not use wireless systems⁷.

What reviewers said

MusicRadar's overall verdict was positive for the pedal's intended audience: the review concluded that the Tremonti was less suited to funk or blues players but pushed all the right buttons for everyone else, describing bold, modern performance and hassle-free operation¹. Pedal of the Day's reviewer, Mike B, found the wah easy to use and convenient, with never a question whether it is on, and said the 20dB of boost makes it that much more useful³.

The later MINI version, the Morley MINI Mark Tremonti Wah, got a cooler reception from guitar.com: Simon Bradley scored it 6 out of 10, and while he found all three of Morley's Custom Shop mini wahs robust and solidly made, he noted the differences in their tones can be subtle at best, and the price of admission is high⁵.

Where it came from and where to get it

Getting together with Morley allowed Mark Tremonti to design a wah built to his specifics³. When the Power Wah launched, MusicRadar reported it was available exclusively at Fret12 for $279, for a limited time only⁴. Morley later issued a Mark Tremonti Wah limited reissue in 2022⁸, keeping the same core design, including the 20dB boost that activates with the switchless wah⁸. Tremonti has since extended his signature gear beyond wahs, launching his MT100 signature amp with PRS in 2025⁹.
