The FX25 is an automatic wah wah pedal that varies the wah effect based on the intensity of the guitar strings' attack. The "Range" control adjusts the amount of sweep the wah provides, while the "Sensitivity" control sets the level of attack required to trigger the wah effect.

The pedal is designed to provide a level-dependent wah effect, where the intensity of playing determines the sweep of the wah effect. It can be used for subtle accompaniment or for bold and bright solos.
