RMC3FL Wah to Custom Cocked Wah Pedal Conversion

Here's a genuine Real McCoy Custom RMC3FL Wah Pedal that was bought used by the current owner. The only problem is the chassis, which is cracked, literally falling apart; and beyond repair. The owner has written to Real McCoy Custom, only to be politely informed that they've discontinued the model; and do not have any replacement chassis in stock. The good news is that after disassembling the circuitry, everything is still working fine.

We've finally decided to re-house the circuitry in a rectangular metal project box. As there is no way to recreate the rocker foot pedal, the sweep pot has been repurposed as a simple sweep knob, adjustable by hand.












We have dubbed this stompbox the "Custom Cocked Wah Pedal." Sure, you can't go whacka-whacka like you would on a wah pedal. However, you can preset any degree of toe-down or heel-down tone by rotating the sweep knob. Then, simply engage the pedal via footswitch, and you're transported to the "cocked wah" zone.
