Yep.....That'd do it. You can also change the scale length that way. Or you can get a scale length logarithm chart and do that too. In my case, when I was making boatloads of these things, I had to come up with one and make a marking stick or else my labor costs/time would have exceeded the selling price of the thing!!!
I made a cool one of these for some friends. I got to thinking that if you could have a "Courtin' Dulcimer" then why not a "Courtin' STICK?" So I made the thing out of a 2x4, had to off set the fretboards, and used two huge coffee cans on either end. Its a riot....most ridiculous looking thing you've ever seen.
