Intonation Adjuster

I have a feeling we'll be seeing this one in the Stewart MacDonald catalog before long. It's a mighty accurate tool for adjusting and testing intonation on acoustic guitars:

Dan makes a temporary filler strip for the saddle slot, and then restrings the guitar with the brass block of this ingenious device behind the bridge pins.

Then to adjust the intonation, all he has to do is turn the thumbscrews:

Dan points out that each of the short ends of the rods has sections of that telescoping brass tubing you find at hobby shops. By adding sections, he can approximate the action of the guitar, too.
