RGXA2
White & Aircraft Gray
Design of the RGXA2 centered on developing a lightweight instrument that would bring the guitar and player closer together.
The focus was on providing the player with greater freedom, breaking down the boundaries between what is in the player’s head
and what comes out of the amp.
In creating a lighter guitar, one absolute condition set down was that sound quality could not be sacrifi ced. For this reason,
a great deal of time and effort went into the creation of numerous prototypes. The A2 project had to combine three crucial
factors—great sound, light weight, and suffi cient strength to withstand the huge forces generated by strings under tension.
Intensive research and development led to the creation of A.I.R. (Alternative Internal Resonance) technology. Although it uses
a solid body design, the incredible resonance created by the unique construction method produces a big, open sound that
resonates throughout the guitar’s entire body. To match and compliment this instrument’s unique characteristics, original bridge
and pickup systems were developed—the resulting tone and response shattering the widely accepted concept that “lightweight
means light sound”.
The RGXA2 brings a revolutionary approach to guitar design. The quest for the perfect design naturally took the route of trying to
build the lightest possible guitar, but early prototypes, while incredibly light, didn’t deliver the sound or playing experience that
was essential. The fi nal weight for the RGXA2 was set at around 2.5kg (RBXA2 weighs 3.2kg, 20% lighter than conventional
bass), a perfect balance— around 30% lighter than a regular solid body guitar but with all the feel and sound that players were
looking for. This is lightweight design taken to the extreme.

Original Pickups
Special pickups were developed to match
the RBXA2’s body design. Blade polepieces
and high-output ceramic magnets produce
a unique tone with great attack, clear tone
and smooth frequency response coupled
with solid, driving distorted tones.
LEDs Illuminated Volume
Controls
The 3-control system includes front
volume, rear volume, and master tone
controls. Volume levels for both front
and rear pickups are indicated by LED
brightness. Looks are simply cool onstage.
Original Bridge
To provide the utmost in functionality,
the compact bridge is designed without
any protruding parts such as screws, etc.
Sound tubes passing through the body
underneath the bridge directly transmit
string energy to the body.

RBX4A2
This regular scale model weighs just 3.2 kg and offers superior balance in addition to its
ultra light weight. Fusing seamlessly with the player it offers unprecedented playing comfort
and effortless playability to let you concentrate on yourmusic. Physically light in weight,
sonically it is anything but. A.I.R. technology and newly developed pickups deliver a thick,
robust tone that is clear, powerful, andworks well with a wide range of musical styles.
RBX5A2
The RBX5A2 is a 5-string version of the RBX4A2.
This bass delivers clear, powerful, and rich tone all the way down to its low open B. Its
wide sound range and outstanding playability defy the common concepts of previous
5-string designs, and open the door to a whole new range of playing possibilities.

Original Headstock
Yamaha has moved from tradition with
strong design features including two-
tone 3-D sculpting, cylindrical aluminum
machine heads (RGXA2), and perfect
weight balance, all wrapped up in sleek,
fresh lines.
Original Pickups
Developed with the custom shop at
Yamaha Artist Services, Burbank, the
A2 pickups perfectly compliment the
tonal characteristics of the A.I.R. body.
Designed with the input of some of the
world’s greatest guitar players, the A2’s
powerful tone belies its light weight.
Original Bridge
In rethinking bridge design, Yamaha
has succeeded at creating a compact,
l i g h t w e i g h t b r i d g e t h a t d e l i v e r s
o u t s t a n d i n g f u n c t i o n . R e m o v i n g
protruding screws leaves a simple design
that delivers extended performance
when playing close to the bridge. Special
sound tubes installed under the bridge
pass through the body transmitting string
vibration directly to the body.
LED Pickup Indicator
The single volume control and a 3
position rotary pickup selector are joined
by LEDs surrounding the volume control,
providing bright visual indication of the
pickup in use.
RGXA2 Neck
Fingerboard width is the same as guitars
in the RGX series, like the RGX220DZ,
but with a medium thickness. This
design makes chords easier to hold and
offers greater stability for the left hand.
Greater neck mass also contributes to a
richer sound.
A.I.R. (Alternative Internal Resonance)
Our A.I.R. development team took the design used on the RGXA2 and adapted it for
use with a bass guitar. The instrument’s structure consists of lightweight core material
sandwiched in between solid materials. Strings passing through the backside of the
body transmit energy throughout the entire body delivering outstanding resonance and
excellent response.
