Ibanez RGB300 Soda Blue Matte Electric Bass Guitar While the electric bass is very much its own animal, it shares a common lineage and character with its 6-stringed cousins. For decades, the RG has stood at the center of what represents the prototypical Ibanez electric guitar. This iconic design is recognized as the foundational instrument for modern metal guitar playing, yet bass players have often had to look on when it comes to this venerable shred-machine: NO LONGER! Now, bassists will again experience the heavy tones and lightning-fast RG playability with the RGB series.
