Figuring out "where the frets go" is one of the trickiest things about building a guitar or ukulele. This reference guide has detailed charts that show fret placement for every scale length from eight inches to thirty-two inches, in eighth-inch increments.
With this book you'll be able to build the "perfect" fingerboard for your next project, and have an instrument that sounds great.
This is not a book you'll read from cover to cover - but it IS a book that you'll keep in your shop, and use on a regular basis
