Revolutionary Super-Light 4-String Electric Bass Guitar
The next revolution in evolution. The conventional wisdom in building electric guitars has long been that the more uniform and heavy the material, the better the sound. Yamaha has shattered this concept with an advanced technology called Alternative Internal Resonance, or A.I.R. for short. A.I.R. combines lightweight and resonant softwoods sandwiched between harder tonewoods creating an instrument loaded with sustain and tone while maintaining an ultra lightweight construction. Already proven in the RGX line,Yamaha now offers this sustain and tone in the RBX line with the RBX4 A2.

The Secret of A.I.R. Technology
Alternative Internal Resonance (or A.I.R.) technology utilizes a lightweight wood core sandwiched between a harder, heavier wood on both the front and back of the guitar's body. Special sound tubes pass through the body so that string vibrations normally resonating only the guitar's top are transmitted through the entire body. By exciting the entire body structure and shaping the tone with the hard top and back, A.I.R. construction creates a full, powerful, and resonant tone with distinctive presence and body that are truly unique.
