Guitar Maintenance-How Humidity Influences Wood Guitar?

Why guitar maintenance is so important? Why should pay attention to humidity and how does it influence guitar? Here we will discuss about guitars built with wood material.

Wood expands when soak up moisture and contracts when lose moisture. And strong shift between expanding and contracting will cause problem in many aspects of wood. And this influences full solid wood guitar mostly, then solid top. This is why we always pay attention to humidity when do guitar maintenance.

  1. High Humidity Influences

When humidity is between 90% and 100%, it causes expanding of body,bad sound performance,extreme string height and dropping of beam and bridge.And causes bulge of  the 14th fret on fingerboard. The guitar will not be able to play.

When humidity is between 70% and 85%, performance of sound getting worse, solid top begins to expand and string height getting higher. After months, mouldy smell occurs. The guitar is not able to play as well.

55%~70% humidity is a relative safe range.But it is not allowed to expose guitar in this environment for a long time.Solid top, back and side will expand a little bit and mostly hand feeling goes worse. But guitar is playable.

It is totally ok to expose guitar in environment with 42%~55% humidity. But if the humidity is 35%~42%, fret buzz will occur for string height is lower and deformation of body.

      2. Low Humidity Influences

Solid top will depressed a bit,especially two sides of bridge, and bridge maybe broken after months when humidity is 25%~32%.

When humidity is 20%~25%, fret buzz is surely to appear. The last six frets will cave into sound hole, the string height is lower. After months, crack on top will last till the end of body. The guitar s almost not playable.

10%~20% humidity will cause break of solid top. And string height will quickly get lower.It is visible that rosette is higher than ever. 0%~10% humidity is surely an extreme environment.In this condition, solid top will be broken fast,beam will go out of body and string height will be extremely low. Guitar is not able to play.

      3. Guitar Maintenance

There are ways to maintain guitar under different condition. And remember that full solid guitar no matter classical guitar or acoustic type is more sensitive to humidity.

If the guitar is in high humidity environment, don’t put it in bag or case. Just put it on guitar stand. But make sure the temperature around is not too high in advance.However, if moisture is too low, don’t expose your guitar outside after playing, keep it in bag or case. Humidity regulator is recommended when humidity is low. 

Directly put guitar under sunlight is always a bad idea, It will influence the appearance of guitar and cause deformation. 

Some are used to oil fingerboard after some period. It is actually not necessary, and sometimes it may deform your fingerboard. However, it is necessary to clean body, fingerboard with soft cloth after playing. This will extend guitar’s life.

Remember don’t try to fix any deformation problem by yourself, contact your supplier or guitar shop where you bought it to ask for professional services.
