This is a terrific seeming 4 in 1 pedal which showcases a traditional wah audio, the distinguished MEGA-WAH sound with fattened bass, bigger sweep as well as increased resonant peaks, an auto-wah as well as lastly a cool note-triggered wah which is an envelope filter that really sounds musical. The pedal is activated by a noise-free, wear-free optically-linked pedal mechanism.
