Zvex Effects Ooh Wah II 2004Birdhouse Music
The Zvex Ooh Wah is a unique take on the "sample and hold," or sequenced filter sound. A slew of 8 little knobs on the top of the pedal allow you to set the individual positions of the filter that it sweeps between. An individual LED below each filter knob gives you visual feedback on the position of the sequence, and along with a speed knob that controls the rate at which it goes through the positions. The "4,6,8" selector controls whether all or some of the sequence positions are being used, and the handy "random" switches up the sequence to give you an unpredictable, glitchy sweep!
