Boss AW-3 Auto Wah Pedal

This is what Boss say about the AW-3:

The BOSS AW-3 Dynamic Wah pedal gives guitarists a wide range of classic auto-wah and dynamic wah effects, plus a new "Humanizer" effect which can simulate human vowel sounds. A Bass input provides a variety of funky wah sounds for bass guitar.

The AW-3 Dynamic Wah is the first compact wah pedal to incorporate human voice-type sounds through a new “Humanizer” Mode. Of course, you can also choose from standard up-and-down wah effects, plus a Tempo Mode and resonant synth-like Sharp Mode.

Choose from both fixed and auto wah settings using the Manual control or pedal for tempo input. By connecting an optional expression pedal, the AW-3 can also be used for Pedal Wah effects. A dedicated Bass input permits direct processing of bass guitars.
