Et bien sur la chose LA PLUS IMPORTANTE que tout le monde oublie de faire.......
Alors voici un copié collé de mon site internet (chose que l'on retrouve dans énormément de garanties de manufactures mais que personne ne prend la peine de lire dans les manuels d'entretien)
On voit tellement de personnes se plaindre des frettes qui dépassent de la touche ou des fissures sur les touches mais personne (ni même certains magasins soit disant spécialisés n'y prêtent attention... à la place, l'on accuse le fabricant ou le luthier) ne semble comprendre d'ou vient le problème et comment l'éviter...
Un détail si important qui pourra peut-être sauver certaines guitares d'un futur désastre...

How to take care and protect your guitar against Temperature and Humidity?
(This applies to every wooden musical instrument)
Wood is a porous, organic material and is affected dimensionally by changes in the amounts of moisture it contains. All fine stringed instruments made from solid woods (i.e. oil-finished instruments) are, without a doubt, more susceptible to the effects of changes in humidity than are laminated wood instruments and mass production instruments. These are heavily sealed by many coats of hard lacquer. Natural wood requires ongoing attention to its condition.
The moisture content of wood is determined by the relative humidity and temperature of the surrounding atmosphere. Relative humidity is expressed as a percentage of air’s capability to hold moisture. For example, 30% relative humidity means that the air is holding 30% of the moisture it could possibly hold at a given temperature. The greatest threats to a fine wood guitar are extremes and rapid changes in temperature and humidity.
High humidity can cause softening of the glues used in the construction of the instrument. As wood absorbs moisture from the air, this can cause the body and neck to twist, expand and rise. Conversely, if you live or travel with your guitar to a drier climate (either hot or cold), there is another danger. In areas of low humidity, the evaporation of moisture from the wood can cause shrinkage and cracking, no matter how long or carefully the wood has previously been aged.
The collective experience of all of the major guitar manufacturers today has demonstrated that the ideal temperature to preserve the integrity of solid wood guitars is room temperature, which is about 20.5º C (70º F ). The ideal relative humidity is about 40% to 50%. In the winter, the forced air systems used to heat most homes can drive temperatures up and humidity levels dangerously low for guitars. A good measure of protection against drying out your guitar is to use a room humidifier
http://en.wikipedia.org/wiki/Humidifier. Use a dehumidifier
http://en.wikipedia.org/wiki/D(...)ifier if the room contains too much moisture. In either case, you need to control the ambient atmosphere of your room. At least once a week, use some special oil (Hufschmid Guitars brand of choice
http://www.estalin.ch/en/pr_en(...)s.php) to clean and maintain the fingerboard and body, which will keep them from drying out and will nourish the wood.
When the instrument is not in use, I recommend that you keep it in its case. If you are not using a room humidifier, check the relative humidity periodically and, when needed, use one of the small guitar humidifiers that are available from many instrument dealers. Do not leave the guitar for long periods near a heating vent, radiator or in direct sunlight close to a window. Never leave your guitar in a car or in the trunk of a car and do not expose it to excessive heat or cold.
Cracks in the wood are typically caused by changes in temperature and humidity. While a small crack may initially be alarming, if it is taken care of promptly it shouldn’t be a cause for undue concern. Such cracks may easily be repaired without compromising the structural or tonal integrity of the instrument.
