It has been pretty cold around New England for the last couple of weeks. Keep the heat low in the day and turn it up at night. Haven't had the time to play the DB for about 3 nights, get home tonight and the thing is buzzing like crazy. I had to turn the adjusters on my bridge up about 8 turns to stop the buzz. About 1/8 of an inch, alot higher than usual. A lot more threads sticking out than I usually see. Is this normal? I didn't think this happened to plywood DBs.
