From Tech21:

“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.

BUILT-IN SPEAKER/CAB SIM: The 100% analog SansAmp Tube Amplifier Emulation technology encompasses the entire signal chain, from pre-amp to power amp to speaker simulation. An integral part of the circuitry, the SansAmp speaker simulation will complement any type of guitar or bass speaker cabinet system. You can also place an external IR after a SansAmp to give additional flavor if you so desire. The SansAmp speaker sim is designed and individually tailored for a smooth, even response as would be achieved by a multiply-miked cabinet without peaks, valleys, and notches associated with single miking and many IRs.

For studio and live applications, SansAmp Bass Driver DI is engineered with three outputs:
effected XLR
effected 1/4
parallel, uneffected 1/4

The footswitch activates the Tube Amplifier Emulation circuitry. Disengaging the circuitry enables you to use SansAmp Bass Driver DI as a standard active transparent direct box.”

Operable via phantom power.
Operable with 9V alkaline battery or 9V DC power supply (not included)
