Powerful Two-Band EQ Control

You'll be surprised at how much EQ movement is right at your fingertips when you start playing with the Tech 21 Bass Driver DI's treble and bass EQ controls. Aside from providing +/-12 dB of movement, moving each control knob in mirror settings will read more also affect your signal's midrange frequencies. When you raise both your treble and bass controls, you'll notice a slight drop in the midrange area. When you lower both controls, your midrange will start to increase. In essence, you're getting the benefits of three-band EQ settings without the middle control dial. And that's not all...

Blend, Drive and Presence Knobs for Dialing in Your Targeted Tone

This dynamic pedal features level, blend, drive, and presence controls. The blend control mixes in your Bass Driver's tube and amplifier emulation. Bring it up to hear more of that warmth and tonal color. Your drive control will determine the amount of grit your hear in your signal. Crank it up to bring in some distortion, and dial your blend control back a bit to maintain tonal articulation. Your presence knob determines the high-end harmonics, almost like a high-end distortion control to bring in a bright and sparkly distorted effect.

Versatile Power Supply Options

You have three options to power this pedal up. Phantom power allows you to utilize the house's mixer, or you can use a separately sold Tech 21 Model #DC2 power supply. You can also power this baby with a 9 volt battery if you don't want to worry about having too many cords crowding up in your pedal space.

This baby's tough outer chassis keeps out dirt and dust, and its protected inner circuitry keeps your signal flowing in uninterrupted fashion stomp after stomp.

Tech 21 SansAmp Bass Driver DI Preamp

SansAmp Bass Driver DI gives you the warmth, presence, and punch of a miked-up bass tube amp system in a conveniently portable direct box/pedal format. SansAmp Bass Driver DI can be used as a preamp or stomp box with your existing stage rig. You can drive a power amp and speaker cabinets. Or go direct into the mixer of a recorder or PA. You can also plug into a power amp or conventional bass amp and a PA system simultaneously.

The controls offer a broad range of traditional bass amp sounds, including such meaty styles as Bassman and SVT, as well as raunchy, crunchy overdriven sounds that would typically require a multitude of effects units.


- Presence: controls the amount of definition and upper harmonic content
- Drive: adjusts the overall gain structure and overdrive
- Level: regulates the XLR and effected 1/4" output levels
- Blend: allows you to mix the direct bass signal with SansAmp Tube Amplifier
- Emulation circuitry: particularly useful for basses equipped with piezo pickups
- Bass and Treble: active EQ controls, specifically tuned for bass guitar, that cut or boost +/- 12dB

For studio and live applications, SansAmp Bass Driver DI is engineered with 3 outputs: an effected XLR, and effected 1/4 in., and a parallel, uneffected 1/4 in. 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.
