Precision Straightedges

About This Item

For accurate fretting and neck evaluation.
We make our Precision Straightedges specifically for checking neck straightness and relief, evaluating truss rod adjustments, and pinpointing high or low frets. Available in four lengths, for working on any fretted instrument, from mandolins to guitars to basses.

The narrow beveled edge allows easy and accurate viewing of the gap between the edge and the surface being checked. Made of durable stainless steel with a satin finish for easy marking with a pencil, each straightedge is precision-machined for accuracy to ±.0015" per foot.

These straightedges are also ideal for laying out projects on wood or paper, and for setting up table saws, jointers and other shop equipment.

Made from surgical stainless steel, hardened and tempered for lasting accuracy.

#3850 18" Precision Straightedge is part of our Basic Setup Kit.

For acoustic guitars, our Neck Set Gauge is designed to attach to the #3799 24" Precision Straightedge.

The Perfect Tool For The Job.

I had been looking at straight edges costing twice as much, which were much more then I needed. When StewMac popped up I thought that name sounds familiar. Yeah, Scott's Bass Lessons recommended. Perfectly designed for what I needed for setting the bow in the neck of my bass. And at a reasonable price. And of course coming from a Luthier Supply house it would be well done. Thanks folks for making Bonnie Sing!!

Used a 12" square to check relief for years. So glad I decided to give this a try. It's much more accurate because it spans all of the frets on the fretboard. Also useful for checking fret height on all of them at once.

High price but you get what you paid for!

I've tried buying lower priced straightedges and rulers. They just didn't do the job well if at all. I bought the 18 inch straightedge and love using it. Nice sturdy weight and thickness. Nice beveled edge, very precise. I like using this to check neck relief between the D and G strings. Brings a whole new meaning to precision reading.

Get the 18 inch for electric guitars.

The 18 inch will perfectly cover all of the frets on a fender scale. This is a must to get your neck perfectly straight before you start leveling frets for a full dressing. Go with the 12 inch for an acoustic guitar. These straightedges are well built.

You never know when you’ll need a trust adjustment.

Any time you change the guage of your strings or let your guitar sit for and extended period of time, you could run into trouble with the neck having a hump or a bow in it. With this tool at the 12th fret in playing postion, you can easily tell if you need a truss rod adjustment.

Yes, I did need this Precision Straightedge...

Thought checking/setting neck relief was done enough by holding 6th string at 1st & 14th frets, then tapping at 7th fret and all would be well. My Taylor acoustic wasn't sounding just right lately and intonation was off, unusual for this 1998 414-KCE. Neck seemed fine, new strings didn't help so I ordered this Precision Straightedge. I held my guitar in playing position per StewMac instructions, laid the straightedge across the frets and found there was a bit more neck relief (gap) then I thought. I tightened the truss nut 1/2 a flat, checked again and relief (gap) was barely visible. I gave the guitar and strum and was surprised how much better is sounded. Up and down the neck, capo'd whatever... my 414 was back to its old self. I could not believe what a difference this "little tweak" made (I had always used "full nut flats" to measure tightening or loosening the truss rod - never occurred to me half would make a difference). I'm a believer now
