Before using your fret levelling beam, measure fret heights with a notched straight edge and identify any high frets. Run the 30cm levelling beam along the fretboard until every fret sits level, then re-crown each fret with a crowning file to restore its rounded profile and smooth the edges. Pair this fret levelling kit with the right guitar fret tools and explore our wider range of luthier tools in the UK for a complete workflow, with fast UK delivery.
