After finding that their is no modifications for the Wailer Wah on the Electro Harmonix discussion board. I discovered a solution on my own. I love the sound of this wah, but when the effect is on it is much louder than the true bypassed signal.
Update..Make sure you use a 2k pot & install a SPST switch on one of the added battery wires. I used a cheap pot with attached switch. The battery will drain without the switch
