The AW-2 was replaced by the AW-3 late 2000. The AW-3 added a lot of new sounds, not heard from auto-wahs before. There’s a dedicated bass guitar input, an input for expression pedal, tap tempo but the party piece is the Humanizer effect. Set two vowel sounds and the wah effect will make a sound approximating a human voice alternating between those two vowels. The AW-3 has also the more conventional up and down wah types and a sharp mode that produces a resonant synth-like wah sound.
