A good while back I was trying to mod my Vox wah. I think the entire circuit is somehow (insert F word)ed.... Now, all I want is a drop in replacement for a V847. Most of what I see is for original cry baby or "Clyde". I have no idea who Clyde is or why that "60's" circuit would be be relevant today. So, who knows of a reputable source for drop in circuits for a wah pedal? Doesn't have to be Vox specific, just needs to fit the housing.
