How is the Banjo Bolster Different from Conventional Stuffing Methods? - Part 2

By treating the banjo’s tone chamber (pot) as an acoustic space, the Banjo Bolster functions as a sound absorber, specifically targeting undesirable sonic energy caused by reflected sound.

As reflected sound enters the Banjo Bolster it is scattered and dissipated by the polyester fibers, significantly reducing their impact on the banjo’s tone.

"It works to an astonishing degree to damp the metallic overtones and not the musical ones -- and has virtually NOTHING in common with the sponges, rags, and socks that people stuff between the head and dowel stick or co-rod at the neck."

He also does fascinating research into the physics of the banjo!)
