Choosing Strings
General mountain dulcimer or music discussions
Hi @natebuildstoys. I never buy packaged string sets for my dulcimers. I buy single strings, although for some gauges that I use a lot, I buy them in bulk through JustStrings.com or Folkcraft.
But the first step is to figure out what gauge strings you like. I prefer strings a little heavier than most, tuning DAd, I use .026 bronze wound for the bass, .016 for the middle, and .013 for the melody. I think .024, .014, and .012 is probably more standard.
Once you figure out what gauges strings you want, just buy them as singles at any local music store. You only have to specify whether you want ball end or loop end.
And yes, the string gauge calculators err on the light side. But once you know that, and once you've developed your own preferences, you can still use the calculator, making the necessary adjustments.
Your bridge might have to be adjusted slightly depending on string gauges. But if the intonation seems OK, don't worry about it. On my dulcimers with moveable bridges, I tend to check the bridge placement periodically, as in whenever I put on a new set of strings or perhaps before a performance.
