For accurate fretting and neck evaluation. Super accurate straightedges for precise fretting and neck work.

Our straightedges are made specifically for checking neck straightness and relief, evaluating truss rod adjustments, and pinpointing high or low frets. Four versatile lengths are available 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.

#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.

Nothing to do without this.

It Gets The Job Done

Well not much to say. It's a simple tool that works like intended

Well made.

I own a few larger straightedges in 24" and 12" that I got elsewhere. I thought they were all that I needed. I realized I was wrong and really needed a 18" for the guitar. I looked elsewhere but couldn't find one with a tapered edge so I bit the bullet and bought this. The quality is great and it's perfect for what it does. It's made in the Good old USA too. A+

life is easy now

This piece of metal is lightweight and the tapered edge makes seeing the frets easier. I use the top side for some other jobs worth the money. If you need it, Stew Mac has it. Friendly service reps, fast shipping, and well packed: that is why I keep coming back.

Great quality

Specialized tool

Nice to be able to get precision tools in the right sizes for the job, but would be nice if they were thicker and could stand up by themselves, maybe with the "knife edge" on the opposite side.
