What Is The Tech 21 SansAmp VT Bass DI?

For the pro on the go, the VT Bass DI covers a lot of ground in a small footprint. This multi-function, multi-application format features three different outputs. You can complement your current rig, record direct, drive power amps and go direct to the PA. Just throw it in your gig bag and you’re ready at a moment’s notice.

The VT Bass DI is a multi-function pedal with an abundance of knob controls. It is easy to use and features Tech 21's proprietary, 100% analog SansAmp technology.

The continuously-variable Character control sweeps through decades of distinctive sounds. You can explore and tailor various eras simply by turning a knob. In addition to modifying the frequency response, the Character control also influences the attack and drive characteristics. You can refine your tone by adjusting your gain and tone settings after tweaking the Character control.

The VT Bass DI functions as a pre-amp, a stomp box, and as a direct box. In bypass, the VT Bass DI converts the instrument signal to a low impedance balanced output. This prevents signal loss and sound quality deterioration caused by long cable lengths. When you engage the SansAmp Tube Amplifier Emulation circuitry via the on-board footswitch, it not only converts the signal, it gives you the sound and responsiveness of a miked-up pro stage rig -- direct into a recording console or P.A. system. You can also simultaneously plug straight into a power amp or conventional bass amp.

As with each SansAmp model, the controls are designed to give you the flexibility to customize your own sound. After all, the greatest inspiration comes from having the sound that’s right for you.

The VT Bass DI can be used with a bass amp rig as a pre-amp or as a stomp box, depending on how you connect the output. You can drive a power amp and adjust your stage volume using the Level control. You can also record direct to a mixer/recorder using the XLR or 1/4" output.


Drive: adjusts the overall amount of gain and overdrive, similar to when the output section of a tube amp is being pushed.

Character: modifies the frequency response, and affects attack and drive characteristics. Settings below 12 o’clock will give you the ‘70s powerhouse, the SVT. Around 12 o’clock will introduce you to the studio staple, the flip top. Above 12 o’clock increases the gain and crunch for less polite, modern rock, indie bass sounds. Full up gives you distorted bass tones fromYes to Crimson to King’s X styles.

MID, LOW, HIGH: Unlike passive controls that only cut, these active tone controls cut or boost ±12dB from unity gain (12 o’clock). Mid is 500 Hz. Low is 125 Hz. High is 3.2kHz.

BLEND: allows you to blend the direct instrument signal with SansAmp Tube Amplifier Emulation circuitry. In most cases, you will probably have this set at maximum (100% SansAmp). For certain applications, however, such as an ultra-transparent sound or for use with piezo pickup-equipped instruments, you may want to blend-in the direct signal to achieve your desired sound. Note: When Blend is at minimum, the SansAmp Tube Amplifier Emulation circuitry is bypassed. However, the Mid, Low, High and Level controls remain active.

LEVEL adjusts the output level of both the 1/4” and XLR outputs.

BITE: Engaged (in position), Bite activates a presence boost and subsonic filter. This tightens up the sound when you are in distorted settings and adds definition to your notes when playing in clean settings.

SPEAKER SIMULATION: is an integral part of the SansAmp circuitry. The VT Bass DI is tuned to match 10-inch American-style bass speakers. It is designed for a smooth, even response as would be achieved by a multiply-miked cabinet, without the peaks, valleys, and notches associated with single miking. The shape of the speaker curve will not adversely effect or interfere with the frequency response of your own cabinet. The speaker simulation works in tandem with the EQ controls to custom tailor the overall sound. If desired, however, you can defeat the speaker simulation by disengaging the speaker switch (up position).
