Its guitars range from professional quality instruments to all laminate beginner ones. In this article, we will deep dive into the world of Yamaha Acoustic guitars and look at the key features of various guitar series and electronic technologies used in their acoustic guitars.

Brief History Of Yamaha

Majority of Japanese guitar makers started by making copies of established Western models and exporting them through trading companies. Yamaha, however decided otherwise and focused on making quality guitars, worth the price from the beginning and in the process earned an excellent reputation among the players.

It was started by Torakusu Yamaha in 1887, with the invention of pedal driven reed instrument, So, the company has a tradition of building musical instruments for over a century. He later formed Nippon Gakki Co. Ltd that manufactured Pianos. Yamaha started building guitars in 1946 at his Hamamatsu, factory in Japan. Today it is a big conglomerate that manufactures motor bikes, tennis rackets, industrial robots and consumer electronics.

In 1960's, They opened a subsidiary in US called Yamaha International Corporation and began to market Pianos. They started promoting their guitars with Sitka Spruce top, laminated bodies and a patented bracing system in 1964. In 1966, FG180, the first ever made in Japan, Folk Acoustic Guitar was introduced followed by Electric Guitars (SG-2/3, SG/7), Bass Guitars (SB-2), and Guitar Amps in the same year.

This was followed by introduction of first Classical Guitar series in 1967 and first Flamenco Guitar series in 1968. By mid 1970's Yamaha had become first Oriental brand to recognized as the prominent force. In early 1980's they created their own facility to reduce cost but maintain quality.

The instruments are currently produced in US, Japan, Taiwan, Korea and Indonesia. Yamaha Guitar Development Center in California, designs, develops prototypes and customizes old and new models.

Yamaha manufactures wide range of instruments from Piano, stringed instruments, band instruments, amplifiers, sound recording and reinforcement equipment

Various Acoustic Guitar Series of Yamaha

A-Series

Called by Yamaha as the Next Level Series, designed for ideal performance and having the perfect guitars to take your playing to the next level. In our opinion, it is the best and higher end series from Yamaha, made from solid wood and comes with cutting edge SRT (studio Response Technology) Electronics / Piezo pickup system. These guitars have stunning looks, expressive tone and road ready build quality.

Key Features Of A-Series

  1. 1
    Sub-series: This series is further subdivided into #1, #3 and #5 as the core sub-series. However, Yamaha had introduced #4 series as limited edition acoustic guitars. #5 has all the premium and high-end features. It is entirely made in Japan.
  2. 2
    Body Shapes: It has 2 body-shapes - Traditional Western Body Cutaway or A-shape and Concert Body or the AC-shape. A-type body-shape has full body resonance with clear highs and powerful lows, while AC has articulate mid-range and highs with clearly defined lows.
  3. 3
    Choice of Tonewoods: Tops for all the sub-series are made from Solid Sitka Spruce. For back and sides, there is choice between Rosewood and Mahogany. Limited edition #4 series had back and sides made from Koa.
  4. 4
    Proprietary SRT system has separate element to pick up signals from each string resulting in very clear sound across wide frequency band, having greater tonal accuracy and better dynamic response. For models A3 and above, SRT2 is used, which is optimized for stage performance.
  5. 5
    In SRT2 system, two onboard mics are provided in addition to the Piezo pickup. With the help of Blend control switch, the sound of the selected mic and the piezo pickup can be mixed to get the exact desired balance. On-board Automatic Feedback reduction feature can be used used to get rid of feedback issues, if any.
  6. 6
    New scalloped bracing system was developed for the top boards of A-Series Acoustic-electric Guitars. In addition the bracing for the back board was made shorter. This led to more pronounced and louder low mid ranges.
  7. 7
    A3 and A5 series have tops treated with Acoustic Resonance Enhancement (A.R.E) process, which gives it a rich and quality tone.

L-Series

L Series with L standing for "Luxury" is another high-end line of their acoustic guitars. Even within the series, there is a huge price difference with guitars in the "6" sub-series ranging from about $700 to "56" sub-series guitars costing above $7000.

Brief History of L-Series

L31, the first L-Series guitar was launched in 1974. Second generation of L-series was released in 1985 along with the release of LL and LS sub-series. Third generation guitars came out in 2004 with the introduction of LJ and addition of many instruments to LL and LS series. Yamaha started using A.R.E treated wood in L-series from 2008.

The L series was revamped in 2014 and is sometimes referred to as the new L-series in Yamaha's literature. It retains the traditional looks of Yamaha and has a warm and balanced tone suitable for solo and stage performances. These guitars are handcrafted by master craftsmen.

Key Features of L-Series

Common Features of all Guitars in the Series
  1. 1
    All the new models have solid Engelmann Spruce tops with A.R.E treatment. A.R.E stands for acoustic resonance enhancement which is wood treatment or reforming technology developed by Yamaha. In this they manipulate the molecular structure of wood through precise control of temperature, atmospheric pressure and humidity. This change in molecular structure results in enhancement of acoustic properties similar to those found in instruments that improve over time.
  1. 2
    It has modified non-scalloped bracing. The modifications from the previous series were done with the view to enhance the low end tone while retaining the characteristic bright tone of the series.
  2. 3
    Neck profile was improved by changing string spacing and height, neck taper and fingerboard binding to have better playability over the entire neck.
  3. 4
    All the models have 5 ply Mahogany and Rosewood necks with double action adjustable rods. Grade 26 to 56 have a volute at the headstock.
  4. 5
    SRT Zero Impact Pickups: The system provides a separate piezo electric element for each string to correctly reproduce its dynamic behavior. During development of the new pickup system, its impact on tone and appearance of the guitar has been minimized while improving its presence of the instrument. Grade 36 and 56 do not have these pickups.
Segregation of the Series
  1. 1
    The L Series is divided into LL, LJ and LS sub-series. LL has original jumbo size instruments while LJ and LS are medium jumbo and small sized. LL, LJ and LS features 10, 2 and 7 guitars respectively that are currently being manufactured.

APX Series

APX Series was launched by Yamaha in 1987. It featured number of Cutaway Acoustic-Electric guitars with a very comfortable thin line bodies and thin neck profile. Cutaway made top fret access easy and thinner neck profile improved the playability and allowed smoother transition from electric guitar. This makes it ideal for live performance.

While essence of design is same, newer models have more natural look and deeper body. This improves the bass response of the guitar and gives louder volume.

Special Features Of APX Guitar's Acoustic Technologies

  1. 1
    The series provides warm tone without the dreaded "Twang" and harshness seen on some other acoustic-electric guitars.
  2. 2
    Latest models have under-saddle piezo pickups from Yamaha's proprietary SRT (Studio Response Technology) transducer. SRT system makes use of advanced digital signal processing methods to closely recreate the sound recorded in a high quality studio. Data applied for SRT processing for each guitar model is recorded in some of the best studios. These pickups allow the guitars to be played at desired volumes with out any feedback effect by use of AFR (Automatic Feedback Reduction) technology.
  3. 3
    Three different high-end mics are provided with provisions to alter their positioning. 3 band equalizer allows adjustment of Low, Mid and High Frequency levels. Player can make microphone selection, positioning, Equalizer and other selections as per his preferences and playing style.
