Newbie to Dulcimers / 1978 Yeoman
Instruments- discuss specific features, luthiers, instrument problems & questions
There's really no need to post the VSL as you have learned from the builder what was on it to begin with. I would go with that. The configuration the builder used makes it very easy to change tuning from DAA to DAd without breaking the melody string.
With regard to cleaning. For years I've used Martin's Guitar Cleaner/Polish on my dulcimers without any problems.
