Fret Sprout: Why Your Guitar Neck Feels Like a Saw Blade in Utah

It happens every year around January. You pick up your favorite guitar, and as you slide your hand up the neck, you feel sharp, jagged metal edges.
In the guitar world, we call this fret sprout, and if you are looking for a guitar fret sprout fix in Utah, you aren't alone. It is one of the most common winter issues I see at the shop.
The Science: Why Do Fret Ends Get Sharp in Utah?
To understand fret sprout, you have to understand wood. Your guitar's fretboard is made of organic material (Rosewood, Ebony, Maple). Like a sponge, wood expands when it absorbs moisture and shrinks when it dries out.
Utah winters are brutally dry. When the relative humidity in your home drops below 30%, the wood of your fretboard shrinks.
However, the frets are made of metal (nickel-silver or stainless steel). Metal does not shrink in dry air.
So, when the wood retreats, the metal stays put, leaving the sharp ends sticking out past the edge of the binding or wood. It’s a classic symptom of the "High Desert" winter.
The Solution: Professional Fret Dressing
While humidifying your guitar prevents this (see my Winter Survival Guide), re-humidifying a guitar often won't fully retract the frets once they have sprouted significantly. You need a physical fix.
As a Luthier in Utah, fixing sprout is one of my most common winter repairs. The process involves:
Masking: I protect the wood of the fretboard with tape.
Filing: I use specialized files to trim the metal ends flush with the shrunken wood.
Beveling: I round the edges over so they feel smooth and comfortable again.
Polishing: I buff the ends so they don't drag on your skin.
The good news? Once I file the fret ends down to accommodate Utah's driest weather, they usually stay good for life. You essentially "acclimatize" the guitar to our local environment.
Can I Fix Sharp Fret Ends Myself?
I love DIY, but I recommend caution here. Taking a metal file to the side of your guitar neck carries a high risk of scratching the finish or damaging the binding if you slip.
If your guitar feels like a cheese grater, don't suffer through the pain.
