Lisa, Dan has a great method of labeling his instruments. #17-20 would be the 17th instrument that Dan built in the year 2020.
I'm curious as to what the #17-20 means in your jotted down tab notes, Dan?
#17-20 is the instrument it was recorded with. I recorded it once before and wasn't happy with it and tried it again with this piece.
A beautiful tribute to Cari, Dan.
