The Rackmount SansAmp

Get to know them!

Just like its exceptionally popular pedal predecessor, SansAmp RBI offers you an entire sound spectrum of the most coveted traditional and modern bass amp systems - including mondo overdriven tones that typically require a complex mass of gizmos that weren't even designed for bass in the first place. Sample settings, such as SVT- style, Bassman-style, King's X-style, and Crimson-style (to name a few) are included in the owner's manual to get you started.

Familiar controls

Drive adjusts the overall amount of gain and overdrive; Presence brings out the upper harmonic content and attack; Blend allows you to mix the direct instrument signal with SansAmp Tube Amplifier Emulation circuitry; and active Bass and Treble controls cut or boost +/-12dB.

What's new?

SansAmp RBI features a dedicated Mid control; individual Level control for the XLR out to optimize your amp's output relative to the P.A. system; Effects Loop; Mix 50/50 switch to configure the Effects Loop in series or parallel; 1/4" rear input and XLR output with select- able levels; buffered uneffected XLR output to run a dry signal to a separate channel; Footswitch input to engage unit; and Footswitch output to chain and toggle between another SansAmp RBI.

The SansAmp RBI gives you a truckload of bass amp rigs in a single rackspace. When you start with a solid foundation of tone, you can travel as heavy or light as you like
