The Yamaha LL6 Acoustic Guitar and the Properties of the Wood Used in Its Manufacture

An insight into the probable durability, longevity and ageing affect on an instrument can be gained prior to purchase due to the common use of certain woods in the manufacture of the guitar. As woods are the most critical components in both the construction and final sound of a guitar it should be viewed as an important element when deciding on whether to purchase an instrument. The Yamaha LL6 uses Rosewood for its back and sides and has a solid spruce top, the heavy and oily Rosewood chosen primarily for it's comfort to the human touch with the mellow tone projection being rounded out by the dynamic response of the Spruce.

The majority of the sound produced by the Yamaha LL6 will originate from the body and includes a strong fundamental with muted high frequencies from the Rosewood whilst being enhanced by the more resonant and high frequency attack of the spruce. This instrument has a tremendous open mid-range and full low end with excellent sustain and pronounced reverberant tonal quality caused by the delays of certain harmonics from the Rosewood. The clear highs and lows and amplified sounds produced due to the Spruce help to propel and increase the volume and tonal qualities of the more muted Rosewood.

The Yamaha LL6 top has been produced using Yamaha's proprietary A.R.E. (Acoustic Resonance Enhancement) technology which uses precision controlled humidity and temperature to manipulate the molecular properties of the wood to produce the characteristics of instruments that have been played for years. Instruments made with woods processed this way produce a tonal richness that is equivalent to having a brand new vintage instrument.

The Neck, Bridge and Fretboard of the Yamaha LL6 are comprised of woods that will bear up well to repeated contact with a guitarists oily fingers. The use of the heavier woods on the neck will provide protection to the instrument, in the long term, from the high tensile strain imposed on a guitar which has steel strings. The overall sound of this instrument is given a top level which has a warmer, smooth tone and thanks to the ebony both a feel that guitarists like and a dampening of string vibration. To help maintain the complexity and variety of tones produced and to condition of this instrument consideration should be given to both environmental conditions and proper maintenance of the body.
