I don't feel like I'm experienced enough to present on DAA tuning, but I can share the invitation with my instructor and see if he might like to do that. BTW, our class has a group page on Facebook called Dulcimers of Southwest Missouri . We'd be pleased if you'd join the group.
This sounds great Dave! Just curious, what tuning(s) do you play?
Thanks for pointing that out Dusty. 
I removed the 9 from the 8-1/2 fret.
I got this box dulcimer on July 20, 2023. It has 24 3/4" VSL with overall length of 29 5/8". The width is 1 1/2", box depth is 1", total depth is 1 3/4". Asking $350 plus shipping via USPS Ground Advantage. My zip code is 65708.
The previous owner described it as "Ron Gibson Mountain Dulcimer. #105521, Tennessee Music Box."
I thought I wanted the extra fret, but I'm having a hard time with it. Maybe later on when I have more experience. Here's a short of me playing.
Thank you Ken! I have bookmarked the chord wizard, and expect I will be consulting it often.
Do you have a comprehensive DAA chord chart you could post? The chart I have shows only D Major, E Minor, F# Minor, G Major, A Major, B Minor, E Major, C Major, and C# Minor. I am especially interested in what additional chords may be formed using the 1 1/2 fret. Thank you!
