All MMFX wahs come with panel mounted Saturation and Cream knobs. The "Saturation" knob will vary the amount of "wah" in the output signal.

The "Cream" control will vary the amount of peak in the wah. You can select from a spikey ear piercing sound to a bassed over and heavy sound. This with added to the Saturation control and the Freq. Selector gives you almost limitless results. And the fact that these are panel mounted gives you the flexibility to change your sound on the go. Some pedal have similar setups but use little circuit board trim knobs, which can be troublesome if needed a quick change is your sound.
