Boss AW-3 Dynamic Wah PedalBring on the funk with the AW 3 Dynamic Wah Pedal from BOSS. By itself as a stompbox, the AW 3 functions like an auto wah. Set the rate and let the funk begin. For easy tempo changes, the tap tempo mode allows you to use the footswitch to tap out the desired tempo, and the AW 3 will follow. The AW 3 also functions dynamically, like an envelope filter, using the level of your guitar's signal to modulate the "position" of the wah. Funk and fusion
