The all-analog PW-3 delivers Pro wah tones in a rugged, space-saving design that conserves precious real estate on your pedalboard. Newly developed by BOSS, the pw-3’s rich mode has a uniquely full wah voice that retains the low-end definition and fullness lost with typical wah circuits. Want a more traditional tone? Just flip the rear-panel switch to vintage mode for that classic wah vibe.
