ZVEX Effects Super Seek Wah Filter (Vexter Series)This product is a far more advanced version of our original Seek Wah and Seek Wah II. Basically the Super Seek Wah is sort of a combination of a tremolo pedal and a wah wah pedal. If youre familiar with seventies synths, its exactly like an analog sequencer controlling a mellow band pass filter. New features include: Tap Tempo MIDI tempo control Glissando Expression Pedal control over tempo_and glissando Adjustable number of stages from 1 to 16
