Boss FT-2 Dynamic Filter 1987 s/n 786200 Japan in very good condition and in full working order.

The FT-2 is an Auto Wah pedal that fits into Boss line of Auto Wah's between the TW-1 and the AW-2. The cutoff frequency knob sets the central frequency and gives the FT-2 more active control that goes a step beyond other Auto Wah's. In Manual mode, the unit has EQ-like capabilities for creating tonal effects with a specific frequency. This pedal can be controlled by the touch sensitivity of the guitar string or add an external expression pedal to control it like a wah.
The Cut Off Frequency knob is the most important control on the FT-2. It sets the center frequency where the effect occurs and can alter the effect completely. There's Up/Down modes as well as a manual mode where the FT-2 works as an equalizer making it possible to create a cocked wah sound when used without an expression pedal.
