We have been designing and building custom mountain dulcimers here in western Washington State for about 8 years and am only sorry it took this long to get this handy reference book. It is most helpful to have a column that shows the note name for each fret. The only thing that would have made it better would to have a column for measurements in fractions of inches for those of us that don't have rulers marked in 1,000's.
I liked the set up of the spacing charts, with dimensions from fret to fret and nut to each individual fret it makes it easy to keep on track and avoid accumulated error.A little difficult to zero in to dimensions, but with a good rule and a digital caliper, doable. Happy with purchase.
I ordered fret position book thinking it would really help me out. All measurements are in 100’s of inch. I have yet to find a tape measure that corresponds to these measurements. I do have one in metric so I used Stew Mac’s metric equivalent. Sorry Folkcraft!
I am considering ordering again soon, I have sent your company info to similar friends hoping they will order you as well.
just what I needed, thanks
