Since 1987, bassists who want the power and versatility of active electronics and the speed of the fastest neck available have made Soundgear standard equipment in every genre. As music evolves, so does the Soundgear concept. The SR500 family is one example of this evolution. The 4-string version is a huge upgrade in playability and tone. The SR500 models feature a fast SR4 neck, a mahogany body, and Bartolini MK1 pickups. Onboard Bartolini 3-band EQ provides precise tone control.
