The Tech 21 SansAmp RPM footswitchable preamp packs a ton of features into a single rackspace unit. Adapted from a pedal SansAmp unit, the versatile SansAmp RPM includes a preamp, an effects loop, semi-parametric EQ, Drive control, active bass, mid, and treble controls (with +/-12dB of boost/cut), and tube amp emulator circuitry. Now you can introduce gain and overdrive into the signal path without losing the clean punch of your bass sound (a handy feature for bassists who want to add some grit to their tone). Want some truly monsterous bass sounds? Try the SansAmp RPM.

- SanAmp RBI - $225: Missing the input screw, still works with out it. Pretty cheap fix. Still works great. Has a mid range knob the the pedals don't. Really loved how this thing sounded in comparison to my pedal. Very convenient Selling because I am downsizing. These are $329 new & i am asking $225 for mine. Message me to discuss any questions.
