McWah

Tone and Reliability

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.

Hand Crafted and Assembled

Every McWah is wired and assembled by hand in our Baltimore workshop with hand selected components that are the highest quality we can source. From our in-shop, Hand-Wound 500mH “Small-Hole” Halo Inductor, to the CTS ‘Premium Series’ McCon-O-Pot II Potentiometer, or SwitchCraft Jacks, and True Bypass Wiring: rest assured that if we could make our pedals any better, we would.

McWah

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.

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.

Product Specifications
 
  • All Hand-wired circuitry. Every wire and component is placed one at a time by us, not an outsourced entity.
  • An Adjustable Tension Foot Treadle to accommodate various playing styles
  • Heavy Duty Custom Powder Coated Zinc/Aluminum Case (…Really, its pretty hefty)
  • True Bypass wiring to prevent excessive tone sucking when in the “off” position
  • 1% tolerance resistors for better consistency in tonal recreation wah, to wah
  • All High quality, Low-Noise capacitors for better filtering, and freq. response characteristics
  • A Potted, Wax Sealed, Hand Stamped, and Hand-Wound (by us) 500mH “Small-Hole” reproduction “Halo” Inductor; nearly identical to the ones found in a “Vintage” 1967 Clyde McCoy (which various monumental recordings showcased over the years).
  • Carefully measured, and hand selected modern transistors (for maximum chewiness and range of expression through out the operating band with low power consumption, consistency, durability, and shelf-life).
  • A RoHS Compliant, through hole soldered, solder-masked, and protective coated board made in the USA (designed by us in our shop, not a foreign entity) which greatly reduces the chance of poor solder joints and cracks – as the woes of gigging can be hard on gear.
  • Heavy Duty 9VDC Battery Connector
  • Heavy Duty Carling On/Off Switch
  • Heavy Duty SwitchCraft Input/Output Jacks
  • Standard 2.1mm “Boss Style” 9VDC Input Jack
    • Zener Diode protected for small voltage compensations, and accidental reverse power conditions. (Plugging the wrong power supply in for example.)
    • An Electrolytic Capacitor has been added inline to thwart input voltage ripples (cheap power-supplies for example).
  • CTS ‘Premium Series’ McCon-O-Pot (II Gen) Wah Potentiometer
    • ROHS
    • 100K Impedance
