Thanks again, I've always put the wah first in line after tuner. I'm only putting the wah in front of a Blues Driver. The Slash wah does sound better than the original but there's still that one point of when the tone goes from nasily (for lack of better words) to muffled that the signal just thins out. I'm trying to coordinate the full sweep of the wah with a nice slow bend which sounds great until I hit that one spot where it doesn't? I appreciate all the help, time and links you've provided Christopher. I'll keep playing around with it. Thanks again. Dale
