MusicNomadTri-Beam 3 'n 1 Dual Notched Straightedge & Precision Straightedge for Acoustic and Electric Guitars including Fender, Gibson, PRS (MN821)

Great piece of kit. Invaluable for guitarists. This item seems very well machined and accurate (unlike some cheaper brands) well worth the money.

Worth every penny, it's extremely accurate and straight. Very good quality

Looks like a well made bit of gear and will be super helpful with guitar maintenance. Have had cheaper ones in the past, but this looks to be a lot more precise. and looks dead flat

Just perfect for the purpose, flat as it should be. Very happy to purchase.

This is a precision tool no doubt. Very useful. I set up multiple guitars. I wish I had this sooner. It's made life much easier and the set ups faster.

Amazing quality! A lot of the cheaper ones don’t give you an accurate reading, this music nomad one is spot on.

Pricey but worth every pennyIf your serious about your guitar this is the one to buy

Excellent product and precision quality as expected from music nomad..expensive - yes, but quality products.
