Fret Sprout
Fretted instruments in dry conditions are often subject to fret sprout which occurs when the wood of a guitar’s neck contracts.
This is more often the case in low humidity, or hot and dry conditions. It occurs when the metal frets extend slightly beyond the neck’s edge as the neck wood shrinks.
The difference in reaction to the conditions between the wood and the metal under different temperature and humidity conditions is the root of this phenomenon. When the air gets dry, wood responds by contracting, leaving the once-flush frets feeling like tiny, unwelcome thorns along the edge of the neck.
The fix once you get fret sprout
The fix usually involves gently filing down the protruding fret ends and then polishing them to restore a smooth neck surface.
This process, while not overly complex, requires a careful hand and the right tools — a set of small fine files, multiple grades of fine-grit sandpaper and polishing cloths are essentials.
For those who are not comfortable doing this themselves, a professional luthier or guitar technician can perform the repair. Costs for such repairs vary. We encourage you to check with your local guitar shop of they can help you.
To reduce the risk of fret sprout
There are three main things you could do to avoid or at least reduce the risk of fret sprout with your Bunyip instrument:
- Store your instrument in a case
- Maintain stable humidity levels. Air conditioned rooms are notorious for drying out instruments
- Invest in a small humidifier if needed.
Storing your instrument in a case or quality gig bag when not in use protects it from rapid changes in conditions, helping to keep those frets in place. However, it is the humidity, or lack of it, that is the root cause and if the wood has shrunk, no oil in the world will make it swell back again. Maintaining stable humidity levels during your instrument’s storage can significantly reduce the risk. A small humidifier could be a great investment.
Note: Fretboards made of maple have a protective finish and should cleaned with a damp cloth or ‘Mr Sheened’
