The SoundTank version of automatic wah is a little different than other touch or auto wahs: it has just a hint of distortion which adds some warmth to this great effect. The sensitivity control can be adjusted to increase response to your signal. Not just for wah effects, the AW5 can also be a more subtle manipulator of attack and tone.
