The Yamaha LP1 3-pedal unit is specifically made for your P-121, P-125, and P-515 digital pianos and is a perfect complement to the L125 furniture-style stand. The LP1 attaches to the L125 stand (required), giving you true piano-like pedaling with the traditional soft-sostenuto-sustain pedal arrangement and half-damper functionality. It also puts the pedals in the proper ergonomic position, letting you transition to an acoustic piano seamlessly. Sweetwater's advice: complete your Yamaha digital piano with the L125 stand and the LP1 3-pedal unit.
