This may be a well known combination to some, but I have recently discovered this incredible stack. The sharpness of the attack at the low end of the wah, and even more rapid transition to the more treble tone at the other end of the wah when used in conjunction with an envelope filter is so dynamic. (In my case, I'm using the MC404 CAE Wah with the Mu-Tron Micro-Tron III). You can practically live in the middle portion of the sweep of the wah, and just use the extreme ends for emphasis. It's obviously a little harder to tame than either pedal on their own...and I stay on my strats neck pickup almost entirely as the bridge pickup simply has too much high end to deal with the second half of the sweep of the wah. Anyone else use this combination?
