The BOSS AW-3 Dynamic Wah guitar effects pedal gives you all the wah you need! It’s not just for guitarists – the AW-3 is Dynamic Wah, like two pedals in one, with dedicated inputs for both guitar AND bass. Choose between fixed and auto wah, or add an optional expression pedal. You also get a ‘humanizer’ function that lets you create wild, human-voice type sounds! This pedal can be controlled automatically via a tempo control, or externally using an expression pedal. Put great wah effects into your pedalboard setup with the compact, easy-to-use, and downright awesome AW-3 Dynamic Wah!
