Some new flatwounds have fairly long silks at the ball end, which go over the saddles on my fender bbot bridge, causing them to sound very dead. I saw Duck Dunn had the same issue, and put some small nuts at the ball end of his strings which sit against the heel of the bridge, extending them enough so the silks don't go onto the saddles.
Does anyone know what size nuts will allow the strings with silks at the ends to fit through?
