Quick sorting hat: if your buzzing follows YOUR fingers around the neck, read the chord-buzz guide — that's technique. But if the buzz lives at one address — fret 7 on the G string, every time, played carefully, played by your friend who's better than you, then congratulations: it's not you. It's real estate.
A note buzzes when the vibrating string clips a fret further up the neck. When it happens at ONE spot consistently, something physical lives there: usually a single fret sitting a hair high (or worn low next to a taller neighbor), or a neck bow that pinches string clearance right in that zone. Frets are hammered metal in carved wood. A half-millimeter of unevenness is all it takes.
The detective work (five minutes):
- 1Map it: play every fret on the buzzing string slowly. Write down exactly which frets buzz. One or two neighbors = likely a high fret just above them.
- 2The capo test: capo at the 1st fret and replay the buzzy spots. Still buzzing? The nut's innocent; it's frets or relief.
- 3Check the season: did the buzz arrive with winter heating or summer humidity? Wood moves — necks bow and un-bow with the weather. Seasonal buzz = a relief (neck-bow) adjustment.
- 4Cross-check strings: same fret buzzing on several strings = that fret is high. One string only = could be its nut slot or saddle.
- 5Take the map to a tech. 'Fret 7, G and B strings, since January' gets you a precise fix instead of a shrug.

▲ WATCH OUT
Don't sand anything yourself
Map the buzz, run the capo test, note the season, hand the tech your findings like a detective handing over a case file. One visit, small money, and that dead zone on your neck comes back to life. Some problems really are just the guitar, and those are the easy ones.

Question 1 of 3
Buzz that lives at ONE fret no matter who plays it means…
The cheat sheet
- Buzz that follows your fingers = technique; buzz with an address = hardware.
- Map exactly which frets/strings buzz, and run the capo test.
- Seasonal arrivals point to neck relief — wood moves with humidity.
- Hand the tech your map; never DIY-sand frets.
Common questions
Is a little fret buzz ever acceptable?
Slight buzz on aggressive playing that doesn't come through an amp (or the acoustic's projection) is common, even on well-set-up guitars — many players trade a whisper of buzz for silky-low action. Buzz you can hear at listening distance is worth fixing.
How much does fixing a high fret cost?
A spot-level or reseat typically runs $20–50; a full fret level with a setup, $75–150. A complete refret (old, worn instruments) is the big-ticket rarity. Your buzz map keeps you in the cheap tier by making the job precise.
Why does only my thickest string buzz at one fret?
Single-string localized buzz often traces to that string's nut slot or saddle rather than the fret. The string sits a touch low at one end. Same advice: note it precisely, let the shop confirm.
