Birdseye Maple
Instruments- discuss specific features, luthiers, instrument problems & questions
@marg actually Birdseye is not bad for bodies. I've probably made around 30 or 40 with Birdseye. It sounds great with a cedar top. I was in the store in Pigeon Forge a couple of times when I was a teenager. But I don't know a great deal about the dulcimers. You could probably find out a lot just by searching here for the builder or Pigeon River dulcimers. The "Greenbriar" thing is a little confusing to me, so I hope I have the right dulcimer. But being in a tourist area Pigeon River sold a lot of dulcimers. There is one on Reverb that looks a lot like yours - although yours appears to be a higher end model than one posted there.
