Guitar Setup Tools
Read nut height and file size before choosing
Separate a measurement tool from a file, and check the documented file width for each string before removing material.
Check what the tool measures
A nut height gauge helps establish a clearance at the prescribed location. A scribe makes a reference mark for work on a nut blank. Identify the tool’s reference surface and the units it uses before comparing prices.
Compare every size in a file set
Read the actual width markings. A set intended for light electric strings can leave gaps in the sizes you need for heavier acoustic or bass strings. Match each position to the tool maker’s sizing guidance.
Confirm the work before removing material
Measure and document the initial clearance. Filing removes material. Stop if you cannot identify the required width, contact point or direction from the tool and instrument guidance, and have a technician assess the slot.
