Thanks Ken,
Yes, maybe wasn't noticed when action was higher but as it was lowered it became very noticeable.
I have taken care of the action on a number of my dulcimers among other repairs, but since this one needed a number of things checked over and it wasn't mine, (I was just finding a nice dulcimer for a new player) - well thought better then me working on it.
Good to know that the frets could have raised from the change of where or how it sat for the 30+ years, maybe I should be glad it was only 3 and not more. Even frets on my own dulcimers, I have file down but again looking like a new dulcimer and not mine - I just didn't want to.
All a journey in both playing the dulcimer and caring for it.
Thanks,
