This is an example of the U3 model Yamaha at our store. This piano is used and is meant to give you an idea of the different models we carry on a regular basis. The Yamaha U3 is 52" tall and is thought of as a studio piano with a 'toe block' design. The term 'toe block' refers to the crossmember at the bottom of the foot attaching it to the leg of the piano. This is something that you commonly see on upright pianos meant for institutional use. The idea is that the leg will not snap off during a move.
