The origin of the classic false beat has to do with the entire termination. If the string at some frequency in at any given direction of oscillation meets a termination which either lengthens or shortens the strings effective length in that direction then a false beat will occur. Loose pins in themselves can be demonstrably independent of the occurrence false beats that the picture is most certainly a bit more complicated. That said, the application of CA is likewise most certainly very effective in dealing with the classic false beat. So don't hesitate to use it appropriately. As far as other particular causes you allude to at the end of your post. Anything that can cause the termination to behave as mentioned above will result in a false beat. There is a particularly interesting analogy in an early PTG Journal article by Jim Ellis that deals with the basic physics involved. Its been posted several times the last couple years so a search of the archives will no doubt reveal the date for you. Cheers RicB Hi list, Regarding some of the recent submissions about applying CA glue to the bridge pin to eliminate false beats, I was wondering if this treatment could be compared to applying CA glue to tuning pins? It seems that from reading some calls and responses that this may be oversimplifying the physics of the bridge/pin, but is an origin of false beats loose bridge pins? Also, are bridge pin holes drilled to a specific depth to accept the whole length of the pin or are they drilled like tuning pin holes, allowing space at the bottom.? I've been very, very curious to understand the origin of false beats and how to deal with them certainly. Thanks in advance for any input, Joe Wiencek, RPT
