Your Footswitchable Preamp!
The Tech 21 SansAmp RPM footswitchable preamplifier packs a ton of features into one rackspace unit. Adapted from a pedal SansAmp unit, the versatile SansAmp RPM includes a preamplifier, 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 useful feature for bassists who want to add some grit to their tone). Want some truly monsterous bass sounds? Try the SansAmp RPM.Tech 21 SansAmp RPM Preamplifier at a Glance:

Functional and compact
The SansAmp RPM bass preamplifier is feature-packed! Use the Drive control to adjust the overall amount of gain and overdrive. Active Bass and Treble controls cut or boost ±12dB, while Mid Shift is a parametric EQ control allowing you to select the center frequency of the Mid control. Its sweep ranges from 170 Hz to 3.0 kHz. Mid is also an active tone control, with a cut or boost of ±12dB.
Blend lets you mix the direct instrument signal with SansAmp Tube Amp Emulation circuitry.
There's also an individual Level control for the XLR out to perfect your amp's out relative to the P.A. system.
Flexible signal control
Tech 21 was able to include several awesome connection options to the SansAmp RPM. Included is an effects loop with a Mix 50/50 switch to configure in series or parallel, 1/4" rear in and XLR out with selectable levels.
You also get a buffered uneffected XLR out to run a dry signal to a separate channel.
A footswitch input is made in to remotely engage the unit, and a footswitch output is added to chain and toggle between another SansAmp RPM or SansAmp RBI.
