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.

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.

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

To be honest, I wasn't sure about paying such a high price for a straight edge, but I'm glad I finally did! This is probably THE most used piece of equipment in my process. It's invaluable to know that what your straight edge says is straight IS straight. Its just heavy enough, and the beveled edge makes it easier to mark with precision when needed (its always needed) A+

Very useful tool

I thought the necks on several guitars were pretty straight, however, using the straight edge I was surprised at the additional tuning that could be done to really straighten them out.
