    Some find it useful. It's for determining when the fretboard is straight when doing a fret job. Personally I don't think it is necessary and would rather have a machined and accurate straight edge. They have only existed the last 10-15 years and people have been doing repairs and fretwork for way longer than that. Maybe it would be a good tool in the arsenal if you are a pro repairman. Many notch a metal yardstick and flatten the bottom for the same result.

    I have got mine delivered today. When I place it on my Strat type guitar, the notched don't all fit onto the frets. It fits to maybe first half of the frets, and then the rest just sits on the top of the frets.

    Am I using it wrong? Or is it supposed to be like that?

    Maybe it is only supposed to fit to Les Paul type guitars? I don't have any LPs.

    Found a demo on youtube. Maybe I should be watching them before using it.

    Assuming your guitar has a 25.5" scale and that is what your notched straight edge is too, then it should fit. But some start with a notch that sits over the first fret, while on others the first notch sits over the nut, or just buts up against it.

    So it cannot be used to check all guitars. Quite limited tool then. I have parlour acoustics, jumbos and dreads as well as Strat and Tele type electrics.

    Your link states it is for Gibson and Fender scales....24.74 and 25.5. One side fits one, the other side is the other one. It would be limited to those scales.

    Got you. I have only 1x Fender strat. The rest are parts casters and acoustics and dobros.

    I think I will return it for full refund, and just go for plain straight edge, which will work on all guitars.

    Most of those probably have 25.5" scales. So it will handle most of them. Plus the other side handles any that have 24.75" scales. The 25.5" will even handle 24" inch scales, if you place its 2nd fret notch over the 1st fret of the 24" scale neck.

    Plus the edge between the notches can be used as a regular straight edge that can be placed on the frets.

    So all in all I wouldn't call that 'limited'. ;)

    I would think you could use it as a regular straight edge if you positioned it so that it was riding on the frets.

    I have one of those kind of dual scale length rules. It will work on both a 25.5" and 24" scales. I haven't fooled with it much but you just have to keep turning it over until it lines up, each side is different.

    looks like it would be dead easy to make for under 5$ with a piece of aluminum strip from the hardware store and a file.

    Hardware store extruded aluminum (and steel, for that matter) isn't flat though. It's actually quite wavy. So a proper aluminum straightedge would have to have it's edge flattened on a surface plate. I started off using a steel yardstick but it is a couple thou off over it's 36" span.

    I like the notched edge on my new builds and refrets because I can set the fretboard perfectly flat and then true the frets to it.
