G'day friends -Try a little pressure on the brackets that hold the let-off buttons. I had one piano where this was a little loose and buzzing..... -Brian's notion of moving the piano is also worth exploring, after spending a couple of hours with one piano, we moved it in desperation into the middle of the room....the noise stopped, moved it back...started again....yep, inside the wall! The piano now lives in another part of the room...rather than punch a hole in the wall to find whatever it was! Cheers Mark Bolsius Bolsius Piano Services Canberra Australia
