A.R.E. (Acoustic Resonance Enhancement)

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 (pages 26,27,28) and LX Series 9 model acoustic electric guitars (pages 4,5,6).

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 “ex-

cellent resonance”, “warm”, “mature”, “well settled”, and “clear” were common terms used in the evaluations.

Cases Offer Outstanding

Support and Protection

Newly developed hard and form cases are designed to pro-

vide your L-Series guitar with excellent support and protec-

tion. They offer a stress-free environment that will extend

the life of your valuable instrument while keeping it safe.

The following alterations lead to their corresponding acousti-

cally 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.

A.R.E technology uses precision controlled humidity and tem-

perature to manipulate the molecular properties of the wood

into a more acoustically ideal condition (similar to the mo-

lecular characteristics of woods in instruments that have been

played for years). The process is chemical free making it an

environmentally friendly process as

well.

Tuners

The vintage style brass tuners

found on all #26 model guitars

present these instruments with

a classic look.

Body Selection

Whether you prefer a full-sized LL original jumbo, small

sized LS body , or medium jumbo-sized LJ, the choice is

yours. Each of these body styles is represented in each class

letting you choose the instrument that meets your require-

ments for sound, style, and affordability.

Bridge

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.

Multi-Ply Neck Designs

The ﬁ ve-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.

Cutaway Body

Venetian cutaways offer access

to the upper frets while adding

beauty to these ﬁ ne instruments.

L series original Bracing Designs

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 clos-

est 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.
