Hi JD Would you mind sharing how you calculated this ? Cheers RicB It's easy enough to calculate. If you have C76 of length 100mm at pitch when lying on the surface of the bridge and then lower the wire 0.5mm into the top of the bridge (some indentation!) then, all else, being equal, the frequency of the string will drop about 0.026 Hz. producing one beat per 40 seconds against the proper frequency. The difference will be even slighter as the strings get longer. JD
