Design of the RGXA2 focused on creating a lightweight
instrument that would bring the guitar and player closer to-
gether. The response we received from its release was great.
The resulting sound shattered the widely accepted concept
that “light guitars only produce light sound”, and brought new
users to the instrument thanks to its light weight. Moreover, it
received great acclaim from discerning professional guitarists
and music dealers.
In addition to the great attention the RGXA2 received, re-
quests increased daily for a bass version of this amazing
instrument. So we quickly set about developing a bass guitar
with an A.I.R structure, and produced three models; a regular
scale, medium scale, and 5-string.
The RBXA2 weighs about 20% less than its standard bass
counterpart. Matched with an original pickup system devel-
oped in cooperation with Yamaha Artist Services Hollywood,
it delivers a heavy sound that is both clear and powerful.
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.
Original Pickups
An original pickup was developed
to match the RBXA2’s body design.
It produces a well-shaped attack
and clear tone with presence. Tonal
character is smooth from the low
range through to the high, and it
delivers some truly great distortion.
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.

and open the door to a whole new range of playing
possibilities.
