Straight Edge Scale Indicator for Luthiers Tool, Guitar Neck Fret, Un-Notched, +35 sizes 24.75 25.5 Scales


Description - This is a straight edge / scale indicator for checking or determining the position of frets on a instrument. Its made out of aluminum and the markings are engraved so it will never wear out. It has a .25in Offset Scale. We have lots of sizes listed below. If you are buying three or more scales it may be cheaper to purchase our "Mr. Master" scale that has +35 scales on it.

Offset Scale - What is "Offset Scale". It's a good question because we had to invent the term to solve a problem that is common with these scales. Here is what happens. Most scales are based on the math of how to machine the scale so all the frets will fit. This would work well if it only had to fit the frets, but it also has to fit the nut. The nut can be hugely larger than the fret and not knowing what size the nut might be this is often overlooked. The result is a scale that will not fit. To solve this problem we "Offset" the scale to accommodate variations in most nut designs. As a result, this greatly improves the compatibility of our scales fitting any particular design of guitar or other instrument.

Temperature Declaration - Aluminum can expand and shrink more than you might expect. Its best to use a scale at the same temperature that it was manufactured at. If a scale is machined in a foreign country at 120 degrees Fahrenheit (not uncommon for a manufacturing environment) combined with cnc machining process can push the temperature of the aluminum to 500 degrees or more. And if you used that scale on a cold winter day in your unheated shop it could be off by as much as 1/8 of an inch! That's why we declare the temperature of which our scales are manufactured at: between 65 and 85 degrees. If the temperature of our metal exceeds this range we stop the process to investigate what is wrong or let the metal cool before continuing. This reduces the thermal variation over the total length to a theoretical maximum of .004in. Typical variations can be found in the .002in range or less.

Recycled Packaging and Carbon Footprint - It ships in reinforced recycled packaging and we use green energies whenever possible in the manufacturing of this product. We also use bicycles to make our post office shipments whenever possible to reduce our carbon footprint.

Note: Fret placement on musical instruments are often done by hand and misalignment of the frets as measured by the scale is only an indicator and may not mean a defect in the quality or workmanship of the instrument(s) being checked.

Thank You! The packaging could have been a bit better, it was evidently dropped and it dented the edge on one end. I should be able to sand it back smooth. Other than that I think it will work nicely!
