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

A little pricy, but will do the job nicely!
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

Well done Music Nomad
Brilliant, now I realise my guitars neck needs adjusting I’ll need to buy more tools to fix it. Im new to music Nomads designs but will say as part of the tools I need to build up to maintain my guitars this is a must have. Excellent quality, covers all my neck lengths (PRS, Fender Stratocaster, Tanglewood etc), looks cool in blue and is generally a well thought out design.

Accurate, worth it!
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.

Bon outil mais vendu à fort prix
L'outil est de qualité et repondra à votre besoin mais vendu à un prix vraiment trop élevé.

Good Tool
Straight as an arrow. Notches fit over frets as they should. The notches were all even when held against a straight edge and on a flat machine table. Perfect for adjusting guitar necks.

Good quality measuring tool
For working on your your guitars you need quality measuring tools. This 3 in 1 beam does the job perfectly. It's dead straight,precision ground and the it's well finished. It's aluminium so you have to be cautious with handeling the tool.
