Sans Amp Programmable Bass Driver DI

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

  • 3-channel, programmable rig-in-a-box
  • Drive, bass, treble, presence, blend, and level controls
  • All-metal construction
  • Operates via a 9V alkaline battery, phantom power, or the optional Tech 21 DC2 power supply
  • 7.25"L x 5"W x 2"H

SansAmp 3-Channel Programmable Bass Driver DI Specifications:

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

Comments about Tech 21 SansAmp 3-Channel Programmable Bass Driver DI:

Here's why I love this thing.
First, I prefer passive basses.
Second, when gigging I need fast access to three basic tone signatures -- a mid-boosted one for a balanced mix with the band, a bottom-heavy grindy one for heavy lifting, and a scooped one for funk and solos. Program those in, and good to go, with the option to tweak them a bit for conditions without permanently altering the setting.
Third, after years of lugging heavy, bulky head units I now feed the Sansamp into a 1000W ultralite power amp and have all the headroom I need, without the pain.
Fourth, whenever I meet a new sound man at gigs the first thing I hear is "Sweet, a Sansamp DI."
Fifth, hand-built like a tank in NYC.
I'm sure I can list more, but you get the idea. I've been using it for three years now and won't ever go back to onboard preamps, either on the bass or on the head unit.

Sansamp makes the bass world go round!

Comments about Tech 21 SansAmp 3-Channel Programmable Bass Driver DI:

I've been playing bass now for over 18 years and every once in a while I come across a piece of gear that makes so much of an improvement in my tone that it actually improves my playing. Last year I picked up the Sansamp Programmable Bass DI, and it did just that. This thing makes it possible to get a nice sounding tube grit, scooped slap sound, a clean boost for soloing and so many more tonal possibilities. With three memory locations, it makes it pretty easy for me to store patches to change sounds for when I have to play gigs with the two bands that I play with. I really prefer the sound of the analog circuitry that the BDDI uses as opposed to some of the digital processors (like the Bass PODxt) that are popular right now. I use a Modulus Bass and SWR and Mesa Boogie amps & cabinets and the Sansamp BDDI adds depth, grit and musical highs that I was not able to achieve before, plus it helps my bass to sit well in the mix when playing wtih bands. Sound guys love it too! Buy this pedal , you will not regret it!
