Basically, this is a classic Wah pedal that we all know and many of us have owned, but Friedman wants to improve a few things with the classic Wah pedal. Among other things, he Friedman added a 3-position switch where you can choose how the sweep should be positioned. in addition, a screw has been added to be able to adjust the resistance in the pedal to suit the user. Also, don't miss the addition of an LED that shows when the pedal is on.
