the ROTOR for cello

The rotor is an innovative tool for stringed instruments.
It’s totally handmade by me, in part with recycled materials.

It’s a turning pick, installed on an electric motor, installed on a peg. You can hold it in your hand or fix it on the bridge of your instrument. The turning pick hits the strings and produces some amazing sounds, very rich in overtones.
With different picks (softer, harder, single or multiple) it can play drones, chords, melodies. It doesn’t hurt the strings.
