I love my straight edge and fret rocker, already saved me a lot of money on my 4 guitars
I love my straight edge and fret rocker. I have already used them 4 times to set the action and intonation on my 2 fenders and 2 gibsons. Awesome 👌, worth every cent. Thanks so much.

Great quality
I’m very impressed. Solid, straight and no sharp edges. Surpasses my expectations.

Nice Gauges
Very nice set of gauges. Seem to be straight and at a good price.

Fretboard ruler/level does not fit any guitar I own.
Like others have stated, this thing is junk. I don’t know what guitar it is supposed to fit, but it does not work with my Strat or Les Paul. Also, as others noted, it doesn’t even cover the entire fretboard. Must be made to fit some junior guitar or some such. Ironically, their own product photo of it laying on the fretboard shows that it doesn’t line up properly. Ugh. Wish I had seen the reviews before ordering.

Doesn't align with frets on my instruments
Notched straight edge doesn't fit any guitar I own. Definitely not a Strat nor Gibson 330. The other items seem ok. It doesn't say that it would actually align with the frets on any guitar so I'll hang it in my work area and leave three stars just on the possibility that it is for something I might one day I might find use.

Perfect for Checking Frets and Action
This 3-piece set is super handy for checking string action and fret height. The notched straight edges are easy to use and fit most guitars perfectly. Solid build and very accurate—even as a hobbyist, I can get professional-level readings.Overall, a simple but really useful tool for anyone doing their own guitar setups.

Get set up for a set up
A trio of useful guitar tools to help get the most from your instrument. I've been playing for 50 years, and finally saw the benefit of having the guitar set up correctly. Go online to see how to do it, I'd suggest Paul at milehousestudios for great video advice and a large dollop of humour.

Parfait pour réglage de manche.

Mal producto
El requisito fundamental que debe cumplir una regla es que sea recta. Y mas si se trata de una herramienta de precisión. Esta no lo es.Ademas es tosca, está mal pulida y tiene terminaciones casi cortantes que pueden dañar el diapasón de la guitarra.Nada recomendable. Lo he devuelto.

Perfect set of tools to get the job done - Dad
I bought this set for my dad, who wanted to handle the guitar setup work himself, and he’s been really happy with it. He says all the tools work exactly as described no faults, no surprises and they’ve been helpful for checking string height, fret level, and general setup.While this isn’t a premium set, it gets the job done well for the price. The straight edge worked fine for him, and he didn’t run into any issues with fit or alignment. Overall, it’s a solid value for beginners or anyone doing occasional fretwork and setups with complete accuracy as needed.
