I had the exact same problem on my new 4001C64. The E string saddle rattled around a lot. Fortunately I had the good fortune to havepaul_yan wrote:Congratulations, John!
The only thing I was not happy with was that the bridge saddles, like some 4003s made after about 2005, rattled a bit when the strings were played. I dissasembled the bridge, wrapped a round of thin aluminum foil strip to the underposts between the holes and the trangles, and stick 2 tiny pieces of aluminum foil to the trangle bottoms. Problem solved!
Ken Joseph to fix the problem. He ended up getting a piece of brass to put underneath it so that it stopped moving around. I don't
think aluminum foil would have done the job, the gap was quite large. But it was quite annoying getting the buzz on that string. And as
a newer player I just assumed it was me until my instructor played it and we found the problem.
