BOSS PW-10 Onboard Overdrive Profiles 
 
Since many of the best wah sounds include a healthy dose of overdrive, the V-Wah includes eight different types of built-in overdrive. These include BOSS classics like the OD-1 OverDrive, OD-2 Turbo OverDrive, MT-2 Metal Zone, DS-1 Distortion, BD-2 Blues OverDrive, as well as “Muff Fuzz,” “Guv Dist” and “Booster” modes. Just dial in the amount you want with the “Drive” knob.
