Read the fretboard instead of the frets. Developed in our shop, the notched straightedge has become a standard for evaluating fretboards.

The notches fit right over the frets so you can check the straightness of the fretboard itself, without the interference of worn or badly-seated frets.

Made of machined stainless steel, satin-finished for easy marking with a pencil (cleans off easily).

Accurate fingerboard reading

By GuitarRepairShack from Calgary, Alberta
(Customer's Reviews) Sunday, November 07, 2010

Sometimes when you put a straightedge over the frets the frets tell you something different. Since I've been using this Notched Straightedge it has helped me with numerous fret jobs because IT TELLS YOU WHAT THE FINGERBOARD IS DOING. Love it.

not suitable for some archtops

Just a note to inform that the notched straight edge does not work for some archtops that have longer scales. Measure first and check the fine print.

notched straightedge

I've been thinking of buying this tool for sometime but didn't know if the cost would justify it. Besides, I've always been happy with my straightedge that I've used for years.

I decided to take the plunge and guess what? My straightedge is collecting dust!!!

This has helped to set up guitars without the worry if one fret is a tad high? Just place on the board and adjust truss rod and there you go, spot on.

Exceeds Expectations

By Joe Dowd from Edwall, WA

First, it is indeed as close to exactly flat as is possible.

Second, it's thick enough you can put it on the fingerboard on edge hands-off and adjust the truss rod to get the fingerboard flat.

Very very usable tool.

Not just another Straightedge

This tool is a time saver and time is money in the repair biz... I found the notched Straightedge so usually in helping to speed up set ups as well as fret leveling and fret board repair. The first day I had this tool in the shop it more the doubled the amount I had invested in it. This tool is a must have if your serious about proper guitar repair.
