For accurate fretting and neck evaluation.
StewMac Precision Straightedges are made 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.
#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.
