  • Range
    Gives you control of depth of wah effect.
  • Pitch (Normal/Inverse)
    This switch allows you to change the pedal pitch form NOR(Normal) to INV(Inverse).
    • NOR: Starts pitch on High tone (When you pick the string) going to LOW tones ( While string tunes).
    • INV : Starts pitch on LOW tone (When you pick the string) going to HIGH tone (While string tunes).



The Touch Wah Vintage is a pick controlled wah. That means that instead of you pushing the pedal up and down, it changes the wah sound for you.

You must play, and the TW-1 interacts with your picking style!

The internal circuitry was developed by using a custom coil inductor in the internal filter section, giving you the most "desirable" tones of the acclaimed wah-wah pedals.
