The Auto Wah is a LFO modulation effect shifting the cutoff frequency of a low pass filter. Unlike many such effects, however, it also features a resonance control to create a more extreme effect. A Shape control also skews the LFO wave pattern to give a faster or slower rise while to modulation speed remains the same. There is a Speed control which is enables you to experiment with slowed down wah tones which ring out, or more accelerated water-like effects.
