[pianotech] key problem

[Scott Jackson]

Aha! So you've been tuning too many good pianos! Probably just a tight
balance hole or front key bushing. But even if the customer reports a key,
it could actually be the hammer pinning to blame. If it's a front-heavy key,
it could droop when a hammer sticks. I always test for slow action parts
with the damper pedal down, so as to remove the extra "weight" from the
system.
