"And from things that make bass buzz in the night, oh Lord deliver us" (slight variation on old Celtic prayer). I'm sure this has been handled to some extent before, but there is nothing more vexing to both luthier and player alike than a buzz or rattle in the bass. A few years ago my apprentice asked me to make a list. I got to about 24 before I stopped. What made me think of this now was that we've had two instruments in the shop lately with hard to find buzzes, and one of them for a reason that was completely new to me. Ok, ready? I'll start and you can join in along the way. Starting at the scroll: 1. A string is protruding too far through the peg shaft. 2. A string is touching another string. 3. A capo or gate on an extension is loose. 4. Something is loose on one of the gears. 5. A string isn't going over the nut groove properly. 6. Fingerboard is partly unglued. 7. String is buzzing on the fingerboard. 8. Open seam. 9. Loose cleat. 10. Bass bar has come unglued at one end or another. 11. Cleat doesn't fit properly Ok, I'm going for a cup of coffee. Bob, Arnold, Nick, Jeff? Players? Step on up and continue.
