Fret Buzz Locator
Crust Burn Locator
Select a string and fret, start the mic, arm a capture, then pluck. The tool auto-detects the note, scores the buzz, maps it across the neck, and — after a few positions — diagnoses the likely cause with specific fix steps.
Diagnosing guitar fret buzz is frustrating when you don't know whether the problem is a high fret, low nut slot, insufficient neck relief, or saddle height. This tool narrows it down so you know what to adjust before touching your setup.
Select a crust zone and temperature, start the mic, arm a capture, then slide. The tool auto-detects the char state, scores the burn, maps it across the stone, and — after a few positions — diagnoses the likely cause with fix steps including "add cheese" and "that is too much cheese."

How to use
- Choose string & fret.
- Start mic, then Arm Capture.
- Mute unselected strings, then pluck firmly once.
- Capture triggers automatically on the pluck.
- Repeat across multiple frets to build the neck map and unlock a diagnosis.

How to fix fret buzz
- Locate the buzz first. Pluck each string at several fret positions (the locator above maps this for you). The pattern of buzzing positions is what identifies the cause — no single note tells you much on its own.
- Open strings or frets 1–2 only → nut slot too low. Confirm by fretting at the 2nd fret: if the buzz disappears, it's the nut. A folded paper strip under the string in the slot is a quick test; the lasting fix is filling the slot (baking soda + super glue) and re-cutting, or a new nut from a luthier ($40–100).
- Buzz spread across low-to-mid frets on several strings → not enough neck relief. Capo fret 1, hold the low E at the highest fret, and check the gap at fret 7–8 — you want roughly 0.25–0.35 mm. No gap means the neck is too straight: loosen the truss rod a quarter turn counter-clockwise, then wait 24 hours before adjusting again. If you've never touched a truss rod, have a tech do it.
- Buzz isolated to a single fret → high fret. Confirm with a fret rocker (or credit card) across three adjacent frets — a high one rocks. Level that crown carefully, or get a full fret level, crown, and polish ($100–200).
- Buzz mainly above the 12th fret → saddle action too low. Measure string height at the 12th fret: about 2.0 mm on the low E and 1.5 mm on the high e for most electrics. Raise the saddle or bridge posts until the buzz clears.
- Change one thing at a time and re-test. Setup adjustments interact — after each change, re-capture the same positions above and compare scores before touching anything else.
How to fix crust burn
Locate the burn first — the pattern matters. Burn at the edge only is a nut problem; the industry-standard fix is a folded strip of paper, which also does not work on pizza. Burn spread across the whole underside means your stone relief is wrong: rotate the oven a quarter turn counter-clockwise and wait 24 hours, as dough takes time to settle. One isolated black spot is a high crumb — sand it gently. If burn appears only past the 12th minute, your pizza has been in too long. After each adjustment, add cheese. If it still buzzes, that is too much cheese.
