LS

A.R.E. (Acoustic Resonance Enhancement) is an original wood reforming technology developed by Yamaha. Instruments made with woods processed with this technology produce a tonal richness that is like vintage instruments that have been played for years. This technology is currently applied to the tops on L Series 6 model acoustic guitars (#36, #26) and LX Series 7 model acoustic-electric guitars (#36, #26).

A.R.E technology uses precision controlled humidity and temperature to manipulate the molecular properties of the wood into a more acoustically ideal condition (similar to the molecular characteristics of woods in instruments that have been played for years). The process is chemical
free making it an environmentally friendly process as well.
The following alterations lead to their corresponding acoustically ideal conditions.
* Enhanced low range sustain produces rich sound and thick tone.
* Increased high range response and decay produces a sharper tone and simultaneously controls
dissonance.

The graphs shown below are from actual acoustic spectral measurements taken under controlled conditions with a current L series guitar and a new L series guitar with A.R.E. Notice the enhanced low range sustain and improved high range attack on the A.R.E. guitar. It is also clear that high range dissonance has a shorter delay after the attack. This is hard proof that A.R.E. is effective at producing the desired changes in the wood's acoustic characteristics. These instruments have received high marks from a great number of musicians. Most of their evaluations are identical to evaluations for guitars that have been played for years. Comments such as "excellent resonance", "warm", "mature", "well settled", and "clear" were common terms used in the evaluations.

Non-scalloped, 90° X-type bracing. 8 non-scalloped braces deliver tone that is thick and well focused.

All L-series guitars benefi t from a new non-scalloped bracing design that delivers tone that is thick and well focused. The #36 and #26 model instruments add a square bracing design which utilizes side braces to connect the brace closest to the sound hole on the top, to its opposite brace on the back. This arrangement transmits string resonance to the back much quicker, causing the entire instrument to come alive with bass response, which the player feels as well.

The bridges on all new L-Series guitars offer more overall mass than their predecessors to deliver greater tone from these instruments. Their designs feature smooth lines and edges to keep the playing surface unencumbered.

The five-piece necks on the #36 and #26 models are carved from a single laminated block that features two layers of padauk—an extremely hard wood used for marimba tone bars—sandwiched between three layers of mahogany. This design creates a neck that is exceptionally strong and stable—great for those players who prefer low string height. The #16 and #6 model instruments utilize similar 3-ply design of rosewood between two layers of mahogany.

Newly developed hard and form cases are designed to provide your L-Series guitar with excellent support and protection. They offer a stress-free environment that will extend the life of your valuable instrument while keeping it safe.
