More on Tight pins

[Marcel Carey]

Hi List,

I did get into that kind of situation too some while ago. At that time, I
did use a concoction made of 10% glycerin and 90% alcool. a few (2-3) drops
per tuning pin should make them turn without that noise. You should then be
able to tune normally. Try it on a few and let me know.
