Myth: If it looks good, it's fine

Image for: What to check before you buy a used electric guitar

Many buyers assume that a clean finish and no dents mean the guitar plays well. **Looks can hide problems** like warped necks or repaired cracks. Inspect beyond the finish.

**Reality:** Open the case with care. Check the neck from the headstock to the heel. Look for twists, bows, or gaps where the neck meets the body. Press down each fret at the 12th fret and watch for buzzing. Play every string at every fret if you can. Small dings are cosmetic. Structural warps cost you time and money.

Myth: New strings solve every problem

Some people think swapping strings fixes tone and action issues. That can help. But **strings don't fix bad neck relief or worn frets**.

**Reality:** Fresh strings make a guitar more playable, but listen for dead frets and uneven tone across strings. Check string height (action) at the 12th fret. If action is extremely high, the neck or bridge may need repair. Ask if the seller just changed strings to make it sound better for the sale.

Myth: Any fret wear is cosmetic only

You might be told that worn frets are just ‘character’. That’s only true if wear is light. **Deep grooves make tuning and intonation unreliable**.

**Reality:** Run a magnifier or your thumb along the fret tops. Feel for sharp edges or deep dips. Play high notes and bend strings to see if sound chokes or frets buzz. If the frets are low, expect a refret or dressing. That is a real cost you should factor in.

Myth: Electronics are easy and cheap to fix

Sellers often say pickup or knob problems are quick fixes. Some electronics repairs are easy. Some are not. **Bad wiring, corroded pots, or damaged pickups raise costs fast**.

**Reality:** Plug the guitar into an amp. Tap each pickup with a small metal object to confirm response. Turn all knobs and flip switches to listen for crackles. If a pickup is weak or dead, or pots scratch loudly, you may need a tech. Ask the seller whether the electronics were opened recently and if any parts were replaced.

Myth: A serial number proves model and value

Serial numbers help, but they can be confusing. Not all serials line up with clear model years. **A serial number alone does not prove authenticity or value**.

**Reality:** Use the serial as one clue. Look at hardware, finish, and headstock shape to confirm model details. If the guitar is claimed to be rare, ask for more proof like original receipts or photos. If the price seems too good for a claimed vintage piece, trust your instincts.

Myth: Light tremolo play means the bridge is fine

Sellers may say the tremolo feels smooth and that's enough. Smooth travel doesn't mean it's set up correctly. **A badly set tremolo can ruin tuning and intonation**.

**Reality:** Use the tremolo while plugged in and while unplugged. Check whether the guitar stays in tune after a dive or pull. Examine the screws and springs for rust or mismatch. If the bridge is sloppy or the screws are stripped, repairs add up.

Micro-moment

You meet a seller in a parking lot who hands you a polished guitar and says, "It just needed new strings." You tune it and it sounds fine for a minute, then a fretted note buzzes when you bend. In that moment you avoid a myth: the quick demo hid the fret wear.

Fast check before you pay

Check the neck for twist or bow by sighting down the fretboard.
Play all strings up and down the neck and listen for buzzing or dead spots.
Plug into an amp and test each pickup, switch, and knob for noise or dropouts.
Inspect frets for deep grooves; feel for sharp edges with your thumb.
Use the tremolo and retune; watch for tuning instability.
Look under the pickguard or backplate if accessible for loose wires or corrosion.
Ask about recent repairs and whether there are original case or receipts.
