RGXA2

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.
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.
