Conventional wah pots are not calibrated for many of today’s circuits! Many “boutique” manufacturers either ripped off the old ICAR design, or copied it exactly only to put a new name on it and resell it as their own. (This is NOT an ICAR tapered pot.)
The MCP-II is a culmination of efforts: we worked directly with CTS to design a better performing, more reliable potentiometer for all of us. This new design has 133.3 times the cycle life as the MCP-I and also features tighter torque actuation. It requires NO cleaning, and is moisture/water resistant rated.
An unexpected (and entirely independent) comparison of the McCon-O-Pot against a few competing types was conducted by a keen engineer named Phillip Perkmann. He provided the following graphical representation, to allow others to see it “in action” scientifically speaking. **Note the travel/sweep symmetry — and the intentional elongating of the high-end resistance taper. This is what gives you a more pronounced middle area, and feel while playing.**
