Was it a P22 (or a relative) from the Thomaston plant? Look for the T before the serial # . It was a problem that I think was eventually corrected , but the older models had a sharp departure angle from the v bar to the pin ,especially in the lower row of the bichords.Combine that with a plate that was quite rough and string breakage was common. I'm not sure about the monochords as you describe but as Paul mentioned sometimes its just your lucky day. I had a contact way back when with Yamaha tech services and replaced scads of strings on this model . A little protek might help but be sure to keep the stuff away from the windings . Tom D.> >
