Weight--a cello's standard 20-inch, 8 mm steel end pin weighs 201 grams. In comparison, this carbon fiber 20-inch end pin weighs a mere 42 grams. That is a 79 percent difference! 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.
