During the last couple years when I've actually had a fuzz, I pretty much never even considered putting it after. So I've been playing around with my wah circuit, trying to get a deeper tone out of it through the fuzz, adding a buffer etc...The problem is you can gt the wah to wah, but that magic connection between theguitar and fuzz doesn't happen. So I'm listening to voodoo child, and like, even with buffer and/or other tricks I've been trying, it's just not happening. That's when it occurs to me and I go and hook it up. I'm 99% sure this was what he was running into the bassman when they recorded that, probably backed off the fuzz just enough to keep things managable. Hero worship and tone chasing aside, there's more wah, a richer fuzz tone. I still like it before too, as long as I have a buffer or resistor at the end of the wah, but my minimal playing around with after is yeilding some great and usable tones. Gonna set up like this for a while and see how it goes.
