New Harmony Solid Carbon Fiber 10mm Endpin Rod with Removable Carbide Tip. Rubber Cap is included. Carbide tips stay sharp. 10mm diameter rods are ideal for Basses and some Cellos if the plug has a 10mm opening. 10mm rods for Cello give you more stability. End pins absorb energy generated by bowing, and it is logical that a heavy steel end pin will absorb more energy than a carbon fiber end pin. We believe that a carbon fiber end pin does have a positive effect on the sound produced by a cello and double bass. However, sound is subjective, and only scientific research could measure positive and any negative effects for each individual string instrument.
