The SLB300 is a brand-new type of electric upright bass that achieves natural sound and resonance by using the SRT POWERED system to simulate studio-quality sound in which the body resonance of a double bass was recorded using a high-quality microphone, all the while keeping a semi-solid body structure that emphasizes quietness and portability.
