Used some black gasket sealer and a whittled down toothpick. got it really good in all the way around both lamp buttons. Let it cure overnight and used the exacto knife on them. I had to give a squirt or two of silicone lube to get them moving smoothly again. So far so good! Played the worst offender on the way to work (Victor Wooten classic thump) and no buzzing. I am aalways going to keep some gasket sealer handy from now on.
