We talked with Chris Poland about the Stone Tone for guitar. Now, Sergio Michel talks with Richard Bosworth – concert pianist – about how Stone Tone gives him an extra boost playing.

Stone Tone uses Granite to create a sustain that adds to the stringed instrument. Whether Guitar, Piano, Bass, or another stringed instrument, the granite piece adds more clarity when you strike the notes.

We learn more about Bosworth, including his performance at the White House in 1999.
