Be sure to add me to your favorites list Yamaha 1980's Era Volume / Expression Pedal for the PSR-36, PSR-41 and Other Keyboards with a RCA Jack Input, in It's Original Yamaha Box This is an unusual vintage pedal from the 1980's. It's from Yamaha and was used with the now-classic PSR36 Portatone Keyboard, as well as other models. This pedal has an RCA jack type of connector (see photos), and will NOT work with the overwhelming majority of keyboards made, as they usually take a phone plug type jack. The PSR-36 does have this type of input though (the photos of this pedal being plugged into something are of the input on my own Yamaha PSR-36, not included of course), and the pedal works fine with that model keyboard. The PSR-36's cousin, the PSR-41 should also take this pedal. There may be some other vintage models that take an RCA jack type of input though. There are some scuffs from general use but no major damage. It's in overall very good + shape, and comes with it's original Yamaha Box ... and they're all made in Japan! Please check out my Store!
