Between the specs of an 2006 RMC Wizard Wah and the 2007 model?

I tried emailing RMC a few weeks ago and I've not had a response.

Depends on the month of 2006...I think the fuzz-friendly circuit was made standard sometime last year. That would be the only difference between the two that I'm aware of, and it would only affect the tone if you're using a fuzz with it.

^ Im using it for high gain/clean/funk/rock so it might.

I'll try emailing them again.

It's not the gain that matters, it's that some fuzz pedals sound odd with wah pedals- so unless you're actually using a fuzz, it will sound the same, even at high gain.
