Abstract

Disclosed is a device for improving the tonal characteristics of a stringed instrument. This has been accomplished using a device that interfaces acoustically with the soundhole. The device inhabits space where sound energy waves tend to interfere and redirects the sound energy out of the soundhole. This prevents distortion and delivers more fullness in sound.
