David and list, We have a Yamaha C7 which was causing exactly the same problem, except it was not a small squeak. It came periodically (and at the most inappropiate moments), and usually some change in the contact point between the top of the rod and the leather caused it to go away....for a little while. The technican for the School tried teflon powder, neatsfoot oil on the leather, and other things, all of which appeared to work for a couple of weeks. Eventually, he replaced the leather, and the problem seems to be solved. I've wondered if anyone else had this problem or if we were unique. If you decide on another solution which works, please let me know. Good luck with it.. Deryck Harnett
