How to build a wah-wah pedal
The Wahtz Wah Pedal produces the classic wah tone you've come to expect with a hint of extra bite and
growl. True bypass switching insures no loss of signal when the wah effect is not engaged, and the long life
potentiometer manufactured specifically for use in wah pedals is included to provide years of smooth, quiet
operation. Point to point construction allows advanced kit builders to easily experiment with modifications to
further tailor the tone to more individual tastes.
Warning: This circuit was designed for use with a 9 VDC power supply only.
