Yamaha, Casio, and other keyboard manufacturers produce a wide range of accessory pedals for their instruments but often design them so that they only work with their brand. This can present problems, especially in schools and colleges as music departments will often have a wide variety of keyboards in use.
The FZone SP-1 generic digital piano pedal has a switch on the side of the unit which reverses the polarity making it compatible with any
brand. It can be used as a soft damper, sustain, or sostenuto pedal depending on the capabilities of the keyboard.
Each unit is made of strong chromed steel and the pedal is sprung to feel exactly like a real acoustic piano. It connects via a 6.35mm (1/4") jack plug which is the standard socket used by all manufacturers.
