john, i doubt you have something cutting the string. sounds like a scale problem. i suggest that you send the original string AND it's bi chord mate off to be duplicated. are they the original bass strings? someone may have replaced them or changed the scale. are you sure the string that broke was original? it is even possible the original scale was not that hot. chris >I could use some suggestions for a bass string problem I'm having. > >The piano is a 1920's upright in otherwise decent condition.
