I haven't had time to get into the new Q6 wah advanced parameters yet, but I always thought the Axe wah was great andwas always able to get the sound I was after. I don't understand why some people seem to have struggled so much with it in the past. Here's a clip from back in FW6 years ago with one of my very first wah patches I dialed in. This was before we even had scenes!
I think it is much improved. Feels more like a real wah with sweep rate. Subtle nuances are there now.
My experience is with the AX8 not the II but I am VERY happy with the Q6 Fractal wah improvements - very vocal like. I am probably more picky about wah than any other effect, and this emulation is spot on. I am actually one of those crazy blokes that used to swap out inductors and capacitor values in my wahs to get them the way I liked. This makes life a lot easier. Haha
