Humidity, Temperature and Storage

Wood is easily affected by temperature and humidity changes, therefore taking care of the surroundings of your guitar is very important in order to keep the instrument in a proper way. Gradual changes won’t generally do permanent damage but sudden ones do. For this reason it is important to avoid them and assure that the guitar acclimate to its environment.

As humidity increases, moisture content of wood goes up fast, causing it to expand and swell. When high humidity is combined with high temperature, glue joints could possibly become weakened and may even open slightly. Then, for example the glue under the bridge could weaken causing the bridge to pull off. On the contrary, if the moisture content of wood is forced down in a hurry, portions of it shrink faster than others, causing cracks and open joints. For all these reasons, rapid changes in local humidity are what you want to guard your guitar against. In view of that, you can follow the below recommendations:

  • Don't let the guitar next to a source of dry heat. (e.g. radiators, heater) since they raise the temperature and drop down the humidity of the surroundings.
  • Don't let the guitar exposed to freezing or blistering temperature for a long time, for instance inside a car park outside.
  • Avoid hanging your guitar on an outside wall during winter months. The wall will be cooler than the inside air. The result is a conflict between the temperature of the top and back, with potential damage as a result.
  • Store your guitar in its case when not in use. Humidity is easier to control in a smaller space. This allows the guitar to acclimate to room temperature more slowly, decreasing the possibility of wood and finish cracks.

The Cleaning

The best way to clean your guitar is with a warm, damp cloth. Don't spill a big quantity of water over the guitar. Don't use detergents or any kind of chemical or abrasive products.

Adjusting the Action

Action is the height of the strings and it is very important for playability. If this height is too high it is hard to play, but if it is too low the strings will buzz against the frets.

This adjustment is produced at the saddle of the bridge. Never use the adjustable neck rod for action adjustments. It is to be used to obtain the proper neck relief.

We recommend that a competent person does this action adjustment.

Adjusting the neck

The neck has been made of dried and cured high quality selected wood. However, due to the constant effort the instrument bears because of the tension of the strings and humidity and temperature changes, the straightness of the fingerboard may be affected and it may bend. This is not a difficult problem to solve if the following adjusting steps are followed.

Procedure to check the straightness of the fingerboard

  1. Place an opaque rule on the frets.
  2. Observe the spaces between the rule and the frets. If the fingerboard had bowed you will see some light within that space.

Procedure to adjust the straightness of the fingerboard

  1. Loosen the 3rd and 4th string (no need to remove them) in order to get access for the "allen" nut placed at the lower part of the handle inside the guitar hole.
  2. The adjustment nut acts with a gentle turn of the key. Special remark: It is not necessary to tighten too strongly, otherwise there is a risk of breaking the rod.
    2a. Turning the key clockwise the neck will bend backward.
    2b. Turning the key anti-clockwise the neck will bend forward.

Tuning Machines Maintenance

Tuning machines normally need very little care other than periodic lubrication.


Used Strings

Each player has its own preferences regarding the type of strings. In general, strings with medium tension are good for most of the players.

Replacing the strings

Lay the guitar horizontally on a flat and stable table, assure that there is nothing that could damage or scratch the guitar.

We recommend replacing the strings one after the other in order to keep the tension on the bridge and fingerboard.
