Anybody have a problem with buzzing on an MTD Kingston fretless? I just did some modifications to mine and had it set up by a professional luthier/tech. But there seemed to be a lot of buzz, particularly across the neck at the 13th to 16th fret line area. A straight edge showed the neck to have no high points. We added relief. We raised saddles. Still the buzz. I put on Dean Markley NPS Blue Steels, light gauge, because the ebonol board is twice as hard, I've been told, as ebony. So the nickel plated steels seemed a good choice. Is the ebonol just very bright and am I possibly getting greater than usual string against board noise? Michael Tobias has been great and if I can't rectify the problem locally, he's suggested that I send it back to him. But I just wondered if anybody else had this problem, and if something like a new kind or heavier gauge of string might help. Thanks.
