Used Tech 21 SansAmp RBI Rackmount Bass Preamp / DI

Tech 21 SansAmp RBI designed as a professional 1U rackmount bass preamp and direct box that expands on the legendary SansAmp Bass Driver DI pedal with additional tone shaping and routing flexibility. Built entirely with analog circuitry, the RBI delivers warm tube amp emulation, harmonic overdrive, and highly customizable bass tone without requiring an actual tube amplifier. It has become a long-standing favorite among touring bassists, studio engineers, and players seeking consistent, amp-like tone in a compact rack format.

The RBI features Drive, Presence, Blend, active Bass, Mid, and Treble controls, along with an individual XLR output level control for optimizing direct-to-PA and recording signals. Additional professional features include an effects loop with selectable series or parallel operation, both processed and unaffected outputs, footswitch input, and standard IEC power connection. This extensive connectivity makes the RBI equally at home as a standalone preamp, DI, recording front end, or the centerpiece of a rack-based bass system.

Known for delivering everything from vintage Ampeg-style warmth to aggressive modern grind, the SansAmp RBI offers dependable analog tone and studio-grade versatility in a rugged rackmount chassis. A top-tier choice for bassists who want iconic SansAmp sound with expanded controls and professional routing options.
