Re: Zakk Wah
It has a narrower sweep.....so it won't go as high or as low as other wahs I've used.
The nice thing about this feature is if you're into the '****ed wah sound'. Since the sweep is less touchy it's easier to zero in on the sound you're after and park it.
IMO it's best used with gain. The narrow sweep avoids the extremes, so you don't get the mud or the brittleness of a wider sweeping wah.....but if you're trying to use it clean you may find yourself wishing the toe went a little further.
