Main reasons for a single vibrating note?
Hello all,
I posted a few weeks ago about some snapped butt springs and you were all very helpful. I had some vibrating keys and assumed that'd be the issue since it was the main issue I could see. A technician came and fixed them and put some new bushings on the pedal rods in case they were causing the bushings.
He then put all the casing back on and played it and there were no vibrations, and then for a few days it was great with no vibrations.
But now a few days later the vibrations are back in the same sort of area, around the F# above middle C.
What other things may be causing this vibration? And why might it come and go?
Thank you
