The Duvoisin DSS patented bridge literally connects the string to the heart of your guitar or bass. We like to take the brass ball ends out (check out our instructional video) to improve that connection even further. On top of that, each string lies on its own bridge, decoupled from the others limiting parasitic noise and significantly enhancing sustain. The major differentiator here is the diffusor that insures that you hear the voice of your instrument. It’s a real game changer, 100% Swiss made: Check it out on our website, with new attractive rates when you buy more than one unit.
