If you liked the Zvex Seek Wah and Seek Wah II, you'll love the upgraded Zvex Super Seek Wah. It acts like a tremolo/wah combo and functions like an analog sequencer by controlling a band pass filter that you can adjust and tweak to get your tone. Sync all of your pedals together using the MIDI IN/THRU and then choose between 1 and 16 steps in the sequence to "wah" at any time signature. A special Delta control allows you to speed up or slow down at your convenience, glissando-ing smoothly between steps.
