Tone and Reliability

[/vc_column_text][vc_column_text css_animation=”top-to-bottom” css=”.vc_custom_1488956351323{padding-top: 10px !important;}”]

The McWah started it all for McCon-O-Wah. 14 years ago founder Mike McConachie had the idea to create a wah pedal that had a vibe and tone that rivaled the best classic vintage pedals, while also providing the necessary feel, usability, and roadworthy reliability that modern musicians demand.

To our ears, the McWah very closely tracks the sounds of earlier wah pedals because it is based on the original Clyde McCoy circuit. We wanted “that” sound, but we also wanted for it to have an easily usable middle range and feel. It had to be extremely vocal. The McWah, a mainstay on the pedal boards of Ricky Rouse of Parliament Funkadelic, Greg Koch, Randy Hansen, and more; is a pedal that nails the old Clyde wah sound while being far more versatile, musical, and reliable.[/vc_column_text][vc_raw_html 0=””]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[/vc_raw_html][/vc_column][/vc_row][vc_row 0=””][vc_column css=”.vc_custom_1493772266608{margin-top: 20px !important;}” offset=”vc_hidden-xs”][vc_tabs 0=””][vc_tab title=”Description” tab_id=”3780b18e-1601-2″][vc_column_text 0=””]

Product Description

How the McWah came to be was a carefully studied and concerted effort. Our sole mission, to stay true to the characteristic original vibe that we expect from a vintage wah, while re-creating the necessary bite, warmth, and feel that a modern pedal must have.

In the prototyping days, circa 2003, we acquired several wahs from various companies and manufacturers, paying special attention to grab as many unique units from as many dates as possible. We did this in order to see how each design evolved from the original 1967 patent. We experimented with modern, vintage, and retro/reissue wahs in our quest for tone, documenting what we did and didn’t like about each pedal we tested. This provided us with invaluable information.

To our ears, the McWah closely mirrors the tone of the earlier units, because our circuit is based primarily on the original Clyde McCoy design. This was a fundamental part of our design requirements. We wanted “that” sound, but we also wanted for it to have an easily usable middle range and feel. It had to be extremely vocal.

If you’re reading this, then you’ve probably encountered the same problem we sought out to fix. You have a wah that sounds really good sometimes, but you can only move your foot for what feels like half an inch before the good tone goes away, and in its place is thin, gross, stank. The sweep and feel of the McWah completely alleviates that problem.

Another design and implementation requirement was roadworthiness, and slower battery consumption. Add in a DC jack, power filtration, reverse-voltage protection, and a custom case that provides a longer throw and we were almost there. Last, but not least – we needed a custom tapered and long lasting potentiometer to take advantage of the extra pedal throw. So, we engineered our own potentiometer, in a collaboration with CTS, to fit the bill.

The result is a glorious thing. A pedal that nails the old Clyde wah sound, while being far more versatile, musical, and reliable.[/vc_column_text][/vc_tab][vc_tab title=”Additional Information” tab_id=”4cfcb19c-1feb-0″][vc_column_text 0=””]
