Much more than just a direct box, the SansAmp Bass Driver DI is capable of dialing up big vintage tube tones, bright modern slap sounds, gnarly distortions, and all in between. Three different outputs to drive power amps, recording desks, PA mixers, or simply enhance your current rig. Controls include Presence for definition and upper harmonic content; Blend to combine the proportion of direct signal and SansAmp circuitry; and active EQ specifically tuned for bass with 12dB of cut or boost. VERSION 2  With the popularity of 5- and 6-string basses going beyond fad status and becoming mainstream, we added a switch to adjust the bass frequency to extend into those lower registers. We also added a mid-range control and a switch to adjust its frequency. The core of the SansAmp Bass Driver and all of its tones remain true to its original design.
