Wood is the most crucial element in achieving both desired tone and solid construction. Most set-neck and neck-thru guitars are primarily mahogany, with a separate facing (usually figured maple). This helps create a big, warm sound that helps enrich the high frequency range. For the low frequency of basses, however, it is more desirable to focus on achieving a clear, transparent effect. This is usually accomplished with a primarily maple neck attached to either an ash or mahogany body. There are many species available, each with distinct characteristics. Using various combinations, an almost endless variety of tones can be obtained. The source of the wood can drastically affect the price. I keep my costs extremely low by going directly to the importers and distributors. This eliminates the specialty middlemen that many makers use. Such specialty sources frequently charge five to ten times the amount of a wholesale distributor. In order for wood to remain stable, it must be thoroughly dried. The most crucial area is the neck, where the slightest warp can mean big trouble. To avoid problems, I purchase kiln-dried rough lumber, mill it down to the necessary size, and allow it to air dry for a full year before use. If there is any internal stress, it will show by either warping or splitting the piece during the year.
