humidity and unisons

[Fred Sturm]

I must say I am skeptical that strings ride up bridge pins unless the
wood of the bridge top has been crushed (by tapping down strings on the
bridge), leaving the effective top of the bridge curved. That is, the
wood in the middle of the bridge is "higher" in relation to the string
plane than that by the bridge pin. I find where I get string noise that
can be temporarily got rid of by "seating" the string, this is
invariably the case. The only cure is to remove strings and bridge pins
and resurface the bridge. And it's easy to prevent: just don't tap
strings. Stretch/rub them into alignment instead.
Regards,
Fred Sturm
