The award-winning VARIWAH is possibly the most versatile wah pedal ever made offering pedal wah, touch wah and also a velocity sensitive auto wah in one pedal.
Touch wah settings control the automatic wah each time a chord or note exceeds the touch sensitivity threshold.

The touch sensitive auto-wah allows you to apply LFO swept wah effects but, furthermore, the effect can be controlled by your playing technique - it can be set so that agressive playing activates the effect or vice versa.
VARIWAH features a foot switch and assignable foot pedal which can control many user defined settings. Regardless of wah mode, the foot pedal can be used to change wah speed or depth and can also be specifically assigned to change swell wah depth, swell wah speed, wah filter movement and touch sensitivity.
