Do all Yamaha sustainers aka pedals work on keyboards?

Not all Yamaha sustainers are compatible with all keyboards. Yamaha produces various types of sustain pedals compatible with specific keyboards or pianos. Compatibility depends on factors such as the keyboard or piano's make, model, and input connector type. Yamaha's FC series pedals, including FC3, FC4, and FC5, are commonly compatible with many Yamaha digital pianos and keyboards, but it's always best to consult the user manual or contact the manufacturer to confirm for a specific instrument.
