To assess the fret level and crown on your guitar, you'll need a few tools and a methodical approach. First, acquire a straight edge, ideally a long, perfectly flat ruler or a fret rocker. A fret rocker is specifically designed for this purpose and provides more precise readings. Secondly, you'll need good lighting to clearly see the fret surfaces.
Fret Level: Place your straight edge across several frets at a time. Start at the nut and work your way toward the bridge. Look for any frets that sit noticeably higher or lower than the adjacent frets. The ideal fret level should be completely flush with the straight edge across multiple frets. Any significant gaps indicate high frets, while a lack of contact points indicate low frets. A fret rocker simplifies this process by displaying the high and low points across multiple frets simultaneously.
Fret Crown: Once you've checked the level, you need to assess the fret's crown. The crown refers to the rounded top of the fret. A worn fret will have a flat or even concave crown, leading to buzzing and intonation problems. Use your fingertips or, for a more precise assessment, a small piece of wood (like a toothpick) to gently feel along the length of each fret. Ideally, you should feel a smooth, even radius. Sharp edges or flat areas are signs of wear.
Professional Assessment: If you find uneven frets, especially pronounced issues with level or crown, it's best to take your guitar to a professional luthier. Leveling and crowning frets requires specialized tools and skill to avoid damaging the fretboard. They will use fret files, various gauges and levels to precisely correct any imperfections and keep the frets uniform.
Simple Answer: Use a straight edge (ruler or fret rocker) to check if frets are level. Feel the top of the frets with your fingers to check if they are smoothly rounded (crown). Uneven frets or flat crowns mean you might need a professional luthier.
Casual Answer (Reddit Style): Dude, grab a ruler or a fret rocker. Lay it across your frets. Any high or low spots? Yeah, those need fixing. Also, run your finger across each fret – should be smooth and rounded, not flat or pointy. If it's messed up, take it to a luthier. Don't mess with it yourself unless you know what you're doing!
