I got my REV2 last December, and have been pretty happy so far.
Yesterday I noticed that the Bb key in the fourth octave makes a loud mechanical noise when tapped relatively hard. It seems as if the extended top of the key is hitting the back of the top panel. You can hear it in this short video:
I am not sure whether that was there from the beginning or not, but I assume it wasn't.
- Has anyone else experienced this?
- Would it be wise to open the top panel to have a look there?
Thanks in advance for your help.
