The FT-2 Dynamic Filter is an Auto Wah pedal that offers EQ-like capabilities for creating tonal effects with a specific frequency. It can be controlled by the touch sensitivity of the guitar string or an external expression pedal to control it like a wah. The Cut Off Frequency knob sets the center frequency where the effect occurs and can alter the effect completely. The pedal features Up/Down modes as well as a manual mode where it works as an equalizer, making it possible to create a cocked wah sound when used without an expression pedal.
