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.
