I am selling a Vintage Halifax Wah Wah. Every thing seems to work the heel footswitch to turn on the wah and turn it off. The side switch seems to change the wah to a different tone. The only problem I notice is the potentiometer is a little tight, it doesn't move easily. I used a pair of pliers to move it and it alters the wah tone like it should. It may loosen up with some lubricant. You might need to replace the potentiometer if the lubricant doesn't loosen it up.
