[pianotech] Pedal "tick"

[John Formsma]

Have you isolated the noise? I.e., removed the action to verify whether it's
action noise or noise coming from somewhere on the bottom board?

Fortunately for us, there are only a limited places where noise can
originate. Finding it can be challenging, but troubleshooting methodically
will eventually yield the solution.
