Build this FC7 Clone for you Yamaha or other Keyboard

The Yamaha FC7 Pedal is simply a variable resistor (potentiometer, or pot) with a stereo cable. What you need to make a clone is an appropriate value for the pot, the wiring details, and a case so you can control it with your foot. This video shows you all of that, so you can build your own clone for a small fraction of the FC7's price
