Described by its maker as a combination of a tremolo and a wah pedal, this is a truly bizarre unit. The Seek Wah actually sets the tempo of the music (the leftmost knob controls the speed) and the little switch controls the number of steps (4, 6, or 8). The Seek Wah steps from one wah setting to the next and then starts over when it gets to the end. Like learning an instrument, it's difficult to handle but very rewarding when you master it.
