The Foot Controller / Expression pedal (call it what you will!) Is a replacement for one that I have been using as a gigging musician for over 10 years, the product is very durable and excellent quality.
The Yamaha FC7 Volume Pedal is a heavy-duty volume controller with fortissimo function which lets you accent certain parts of a performance. Adjustable pedal angle, spring point adjustment, and a metal connection plate for multiple-pedal ganging add unique capabilities for various playing styles and setups.
