Bjorn's Description
The Crimson Red Bass Preamp allows us to relive the sounds of bass amplification before extreme clarity, thanks to 400W amps and tweeters, was a thing in the bass world.  The CRB reproduces the sound similar to a single 15" or 18" setup.

CRB allows you to control 3 main characteristics:

Volume: Output volume
Brilliance: Bandwidth control.  At maximum, treble can pass.  Whereas at the most counter-clockwise position, only bass is amplified.
Gain: Boost control. 

The Crimson Red Bass Preamp can be used as a preamp to modern bass amplification setups while bringing back that old school feel of a 60s upright bass and 70s electric bass.
