How to Spot a Refret on a Used Guitar

Short version: a refret is not a red flag by itself. A tidy, well-executed refret can make a used guitar play better than it did the day it left the factory. What you actually want to know is whether the guitar has been refretted, how well it was done, and whether the seller knew (or is telling you). That last part is where a lot of used-guitar disappointment comes from — not the refret itself, but a listing that quietly calls the guitar “all original” when the frets tell a different story.

I’ve had hundreds of instruments across the bench, and refrets hide in plain sight more often than people think. Here’s how I check, in the order I actually do it.

First, why it even matters

Two reasons. One is honesty: if a guitar is sold as untouched and it’s been refretted, what else in the description is optimistic? The frets are a good tell for how carefully the whole guitar has been described. Two is value: on a vintage or collectible instrument, original frets carry a premium, and a refret — even a beautiful one — usually knocks the collector value down a notch. On a modern player-grade guitar it’s the opposite; a fresh refret with good wire is money already spent that you don’t have to spend yourself.

So the goal isn’t to catch someone out. It’s to price the guitar correctly and set your own expectations.

The tells, from easiest to subtlest

Diagram: the most common ways a refret gives itself away on a bound, Gibson-style fingerboard.

1. Binding nibs on a bound fingerboard

This is the big one on Gibsons and other bound-board guitars. From the factory, Gibson frets the board before the binding goes on, then scrapes the binding down so it caps the end of each fret. The result is that little shelf of binding at the end of every fret — the “nib.” Refretting a bound board without wrecking those nibs is genuinely difficult, and plenty of shops simply sand the nibs off and run the new fret full width to the edge of the board. So if you’re looking at a bound Gibson and the fret ends run right out over the binding with no nib — or the nibs look like rebuilt blobs of tinted glue — that board has almost certainly been refretted. Worth saying plainly: the nibs are cosmetic and do nothing for tone or playability, so their absence is a clue, not a defect.

2. Fret wear that doesn’t match the guitar’s age

Frets wear. On a guitar that’s seen ten years of playing, you expect flat spots and divots in the first few positions. If a well-loved, dinged-up guitar has tall, crisply crowned, mirror-polished frets with no wear in the cowboy-chord zone, someone put those frets in recently. Conversely, brand-new-looking wire on a guitar with a worn finish is one of the loudest tells there is.

3. A colour or finish mismatch on the board

To seat new frets properly, the tech usually levels the fingerboard first, which means sanding it. On rosewood or ebony that fresh sanding often looks lighter and cleaner than a board that’s absorbed years of finger oil, and the wood right up against the fret can look newer than the middle of each fret space. Maple boards get refinished after a level, so look for an over-spray edge or a slightly different sheen. None of this is subtle once you know to look for it in raking light.

4. Different wire than the guitar shipped with

If you know what a model originally came with, mismatched fret wire is a giveaway. Gold-coloured EVO or bright, hard-wearing stainless steel on a guitar that left the factory with standard nickel-silver frets means a refret — nobody was installing stainless at the Gibson or Fender factory on most of these. Even a jump in fret size (a vintage-spec guitar suddenly wearing tall, wide “jumbo” wire) points the same way.

5. Glue smears and chip-out along the fret slots

Pull an old fret and you’re left with a slot full of packed grime and, sometimes, old glue; the tech cleans it and often glues the new fret in. Look closely at the ends of the frets and the edge of each slot for thin dried glue smears, filled chips, or little slivers of board that chipped out during removal and got glued back. On rosewood and ebony these show as tiny colour irregularities right at the fret line.

6. A witness line where the neck meets the finish

This one’s for the maple-board and lacquered-neck crowd. If the whole neck was refinished as part of the job, there’s frequently a faint “witness line” — a visible edge where new finish meets old — usually near the heel or the nut. It’s subtle, but under good light it’s there.

When a refret is actually good news

Plenty of the best-playing used guitars I’ve handled have been refretted, and I’d buy them again tomorrow. A guitar that was played hard, worn out, and then given fresh wire by a competent tech is a known quantity: the frets are level, the ends are dressed, and you’ve got years of runway before the next one. If the seller is upfront about it and the work is clean, a refret can be a reason to buy rather than a reason to walk. Stainless-steel refrets in particular are a genuine upgrade for a lot of players — they last far longer and feel slick — and you’re getting that upgrade at a used price.

What I want is disclosure and quality. A refret that’s disclosed, level, and buzz-free is a plus. A refret that’s hidden, or done badly — high frets, sharp sprouting ends, chipped binding, buzzing in spots — is a reason to renegotiate or pass.

The honest caveat

Here’s the part a lot of “how to spot a refret” guides skip: a truly first-rate refret on an unbound board, with matching wire and a clean fingerboard, can be essentially impossible to detect by eye. If the tech matched the original wire, saved or rebuilt the nibs convincingly, and didn’t over-sand the board, you may never know — and honestly, on a player guitar, it may not matter. Don’t talk yourself into false certainty. If originality is critical to you (a vintage purchase, say), the frets are one data point among many, and at that level it’s worth paying a good tech to inspect before money changes hands.

When we take a used guitar in at the shop, the fret condition and any prior fretwork go in the description on purpose — you shouldn’t have to play detective. You can see what’s currently on the bench and ready to ship in our guitars in stock collection.

FAQ

Does a refret lower a guitar’s value?

On a collectible or vintage instrument, yes — original frets carry a premium and a refret typically softens the price, even when the work is excellent. On a modern player-grade guitar it’s often neutral or a slight plus, because a good refret is money and downtime you don’t have to spend.

Is a partial refret (just a few frets) a problem?

Not necessarily, but it can look odd — a few shiny new frets next to worn originals, or a couple of nibs missing on a bound board. Ask whether it was a spot repair or the start of a bigger issue. Done well, a partial refret is fine; done as a quick patch, it can mean the fingerboard needed more attention than it got.

Can you always tell if a guitar has been refretted?

No. A skilled refret with matched wire and a lightly dressed board can be invisible to the naked eye. The tells above catch the common and the rushed jobs; for a high-stakes vintage buy, have a trusted tech inspect it.

Are stainless-steel frets a red flag on a used guitar?

They’re a sign of a refret (almost nothing shipped stainless from the big factories), but they’re usually a good thing — stainless lasts far longer and feels smooth. Just factor in that it confirms the guitar isn’t fretted as it left the line.
