Casio SP33 Keyboard Pedals for PX-150 and PX-350
This 3-Pedal Unit, for use with the PX-150 and PX-350 keyboards, features damper, soft, and sostenuto pedals, all in a single unit that attaches to the CS-67 stand. The SP-33 supports half-pedal operation, so effects can be partially applied if a pedal is partially pressed.
