I'm a newbie and just got my second uke, a Kala Ziricote baritone. My first is a concert. The baritone (which is restrung to be GCEA, high G, IOW typical reentrant tuning) is beautiful and sounds nice, but my wife, an experienced guitarist, noticed a problem. When I pluck the A string, the E string vibrates very faintly. What's going on here? Is the NuBone saddle transmitting the sound? Can this be fixed?
