string buzz quandry

[Baldwin Yamaha Piano Centre]

Hi Matt,
              Sounds as if you have some loose bridge pins or bridge cap. Take
your screw driver and press down on top of the pins and see if the buzz goes away
and the tone improves. If so, pull the pin and run some thin epoxy, or CA glue
down the hole, remember epoxy takes time to cure, CA glue is the quicky field
repair of choice for many of us.
Heating 5min epoxy so it runs like water is also fairly quick. wait about 30min
before pulling the string to tension.
Some times just driving the bridge pin in a little further can clear up the
problem. Use a nail set punch and give it a tap.
Hpe this helps
Roger
