Surely the lack of a good bend on the wire around the pin is as = much a part of the equation as those that think seasonal movement of the = bridge produces a change in the wire to bridge contact area. Having done my stint at local dealerships for the past ten years, I = really believe that most of the instruments, from a variety of = manufacturers, need some type of massaging of the wire at the bridge = pins. I can see it, and I can certainly hear the differences of before = and after application of seating techniques. Like I said, only those = instruments that exhibit no other problems are ever going to respond = satisfactorily, however.=20 This week I kept track of all of the pianos I serviced for false beating = in the treble. I find it amazingly calming to diagnose the offending = pianos' problems and try and come up with either a plan of action or at = least an understanding of what remedies will realistically improve them = or not as the case may be.=20 FWIW here's my findings: Kawai older KG-3 grand --no improvement after seating. Pulled off one = string and found severe cut in bridge top. No chance of fix today. Yamaha P22 -- Had No dealer prep. Improved dramatically after light tap = with brass rod, with no false beating evident.Wire very obviously moves = when tapping. Steinway B -- Hit and miss work over five years. No improvement by = seating with brass rod by tapping or sliding along wire. Did make = significant improvement pulling wire into bridge pin and eliminating a = large radius bend in the wire.=20 Farrand upright -- Last three octaves every wire was beating. Most of = the problem was loose bridge pins. I'm going to let down tension, remove = wire and super glue 'em. I'll let you know what happens. Yamaha C3 -- newer, evidence of some prepping, but several false beating = wires in high treble. Only improved one note after seating efforts. Did = not check bridge top. Kohler & Campbell SKV 48 -- Three years old. Tapping wires produced fair = results, but my opinion is the cap is very soft, allowing bridge pins to = move. Afraid I would dent this cap if seating were done too = aggressively. A.B. Chase 5'3" 1927. Zero false beats. Clear tone all the way to top. = Absolutely amazing. Bridge looks like very hard old wood. Difficult to = even see the grain patterns. Hmmmmmmm, are we missing something here?
