Morley 20/20 Wah Boost
Morley · pedal
The Morley 20/20 Wah Boost is Mark Tremonti's signature switchless wah, built to his specifications with an aggressive 20dB boost that activates together with the wah, so stepping on the treadle instantly readies a cutting solo tone. The pedal automatically shuts off when you take your foot off, courtesy of Morley's switchless electro-optical design with no pots to wear out and silent operation. The wah voice is tuned for hard rock and metal, with a strong, expressive sweep that pairs well with high gain, and the integrated boost helps leads punch through a dense mix. The 20/20 buffer circuit preserves tone, and the tank-like, glow-in-the-dark enclosure is gig-ready. It suits rock and metal players wanting an aggressive, solo-focused wah with built-in boost.
