I need a wah pedal....

RMC wahs are very high quality and there are a few different options to choose from http://www.realmccoycustom.com/WHICH WAH.htm. I bought the RMC4 Picture, it has no knobs on it. The RMC3 is very adjustable with the knobs on the front of the wah instead of the sides.

 

Spend the stupid money and buy a Roger Mayer Vision Wah regular or Special. http://www.roger-mayer.co.uk/vision_special.htm
Every wah that I've tried over the years has failed to give me what I was looking for until I found the RM. You seem to be after what I like in a wah.
Wah pedals I've had; vintage vox and cry baby, RMC1, RMC3, RMC picture wah, Fulltone (both), Zvex wah probe (close but not quite), Proanalog supaquack (awful), Area 51 fully loaded (really great standard wah). I think there were others but not memorable. What I don't like about the conventional wah is the inherent distortion in the sweep as it goes through the midrange. All of the wah's listed had this same problem- apart from the Zvex. The RM Special is a great volume pedal when in bypass mode and is also a great sounding buffer.

 

I agree. RM makes the best ones. I have a Vision wah and I'll never replace it.
