[CAUT] When to restring...

[tannertuner]

Well, it sounds like metal on metal, just like all the new Chinese pianos I've tuned. I've always assumed it would have to be string corrosion through the agraffe because it happens from the lowest A and stops at the capo. Really sharp pitch changes with each ping, not like poor rendering at the capo, where the pitch audibly slides, when tension finally catches up. Unfortunately, I don't use enough Pro-tek to keep it from evaporating out of the bottle before the next time I need it.

Maybe it's our part of the world, but in the tenor section, I tend to experience strings getting caught up ting ting tinging through agraffes long before there's a problem with them moving through the felt.

Are you sure it's the agraffe?    I used to think so too, until I put some protec on the agraffe and nothing happened, then I put it on the felt and all of a sudden the string was moving smoothly.  I have  one 1936 Bechstein M that was brought over by a family as they fled Germany right before the Nazi's got to them.  String tinging was always a real problem, then I tried the Pro-tek on the felt and it tunes just fine.
