So far for me, the hd500 has been 99% perfect. But that last 1% has been the wah models. I'm just not getting the sound I'm looking for. During my gigs, i'm not using it a ton, but it's in there occasionally for either some 70s clean stuff, or a solo here and there (beverly hills-weezer). The last few gigs I've brought out my Budwah and placed it in front of the hd500 just so I wouldn't have to deal with the models. It seems to me that one of my issues is almost that the expression pedal on the hd500 has too big of a sweep. When I bring it all the way down, it seems like the volume completely dies. I've tried adjusting the parameters to some of the wah models, but I'm not there yet.
So for those of you that have a good wah sound, I'm wondering if you will share your tips. Which model are you using? Where are you putting it in the chain? Are you adjusting any of the parameters?
