Holy smokes, its a wah. What does it do? It wahs, and it is gold. What more do you need?
Most people dont know this but much of the wah-wah pedal world uses the exact same circuit layout as the original wahs, with just some component value changes. Because of this, the circuit is just *ripe* for tweaking the values to get different voicings, and thats exactly what this one is. This one features some more modern features like true bypass switching, and it has been tweaked to enlarge the sweep range a bit, and also improve the bottom end.
