Fret Rocker 4 in 1 Straightedge for Frets
- Quickly check for uneven frets
- Durable & strong 3mm stainless steel
- precision machined
This tool is used to check if there are any high or uneven frets in a guitar, bass or other fretted instrument.
The unique shape of this straightedge is designed to span across three frets anywhere along the fingerboard. By 'rocking' the tool you can check if the fret that is in the middle is higher than the others.
Uneven frets can cause fret buzz and may need gluing or levelling.
