I bought a custom McSpadden dulcimer about one year ago, after deciding to learn how to play, and I have really enjoyed it. It has a wonderful, mellow sound and has been a pleasure to play … until now. Within the last few days, my base string has started buzzing in an annoying way. It looks to me like the vibrating string is hitting the first fret. (It might be my imagination but I believe the melody string is starting to sympathetically buzz as well, as of today.)
I have read every Forum Discussion on buzzing strings on this site. Someone suggested using a toothpick to raise the string slightly. Well, when I did that, the buzzing stopped but every note down the string was off key (slightly sharp), which doesn't make a lot of sense to me since the adjustment is right up to the nut. The base string is original and is a wrapped .22 string. I read where someone said a newer string might buzz more than an older string in one of the forums, so I don't think the age of the string is a factor.
I play my dulcimer every single day and I am wondering if I have already worn something out! Is it possible for a nut or the grooves in the nut to deepen? I feel nervous about having someone work on it because I am wondering how they are going to fix it without messing it up.
Any thoughts or suggestions would be greatly appreciated since I am fairly new to the dulcimer world.
