I tried something similar years ago that a friend claimed to have invented. I could not detect any difference but perhaps this one is different. The only device I have found which significantly altered the sound of my Lakewood was a set of Brass Bridge Pins which produced a very bright and resonant sound. Not everyone's taste but worth a try. I have found that most decent guitars, and I have owned and played a few, dont need embellishment other than regular string changes. Same goes for banjos
