Owner's Manual
Tech 21, the Company
Tech 21 was formed by a guitarist possessing the unusual combination of a trained ear
and electronics expertise. In 1989, B. Andrew Barta incorporated Tech 21 and made his
unique invention commercially available to players and studios around the world. His
highly-acclaimed SansAmp™ pioneered Tube Amplifier Emulation in professional
applications for recording direct and performing live, and created an entirely new category of signal processing. While there have since been many entries into this niche,
SansAmp continues to maintain its reputation as the industry standard.
With a full line of SansAmp models, Tech 21 also offers effect pedals and MIDI products, as well as “traditional” style amplifiers for guitar and bass. Each product is
thoughtfully and respectfully designed by Andrew himself with the player in mind.
SansAmp Character Series
VT Bass Rack, an Overview
Simply put, the VT Bass Rack is a rackmount version of our exceptionally popular
pedal, the VT Bass from our SansAmp Character Series. This format, too, offers a historical journey through the most coveted Ampeg®-style bass amp rigs.
For studio and live applications, Tech 21’s proprietary, 100% analog circuitry
delivers the warmth and responsiveness of a miked-up stage rig --direct into the mixer
of a recorder or P.A. system. You can also simultaneously plug straight into a power
amp, powered monitor, or conventional bass amp. The interactive controls give you
access to specific tone shaping characteristics to create your own custom sounds as
well.
Our goal is to provide you with flexible, versatile tools to cultivate, control, refine and
redefine your own individual sound. Tech 21 takes great pride in delivering consistent
professional quality sound, studio to studio, club to club, arena to arena.

Beyond the obvious difference in housing, the VT Bass Rack’s additional features
include an individual Level control for the XLR out to optimize your amp’s output relative to the P.A. system; an Effects Loop with a Mix 50/50 switch to configure the loop in
series or parallel; 1/4” rear input and XLR output with selectable levels; buffered uneffected XLR output to run a dry signal to a separate channel; Footswitch input to engage
the unit; and Footswitch output.

This unit is powered by potentially hazardous voltage. Therefore, observe
the following safety precautions:
1. Read and follow all instructions before using
product.
2. Do not use product near water (such as near
a bathtub, washbowl, kitchen sink, swimming
pool, in a wet basement, etc.).
3. Unit should be located so that its location or
position does not impede the flow of air through
the ventilation openings.
4. Product should be located away from heat
sources such as radiators, heat registers, or
other products, including amplifiers, that produce
heat.
5. Product should be connected to a power supply only of the type described in the operating
instructions or as marked on the product.
6. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the unit.
7. Do not allow objects or liquids to penetrate the enclosure through openings.
8. During heavy use, chassis may get hot to the touch. Handle with care.
9. Protect unit from strong impact.
10. Unplug product before cleaning. Never spray liquid cleaners into the amp: wipe
with a clean, lint-free cloth to remove dirt and film.
11. Only use attachments/accessories specified by the manufacturer.
12. This product should be used only with a cart or stand that is recom-
mended by the manufacturer. When a cart is used, use caution when moving the cart/product combination to avoid injury from tipping over.
13. Amplifiers may be capable of producing high volume levels that could
cause permanent hearing loss or damage, if the exposure to such levels is prolonged.
Such damage is progressive and irreversible! If you experience any hearing loss or ringing in the ears, consult an audiologist.
14. Unplug unit during lightning storms or when unused for long periods of
time.
15. This unit must be earth grounded. To reduce the risk of electric shock, NEVER remove
or otherwise attempt to defeat the ground pin of the power cord. If the provided plug
does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
WARNING: To avoid the risk of fire, electric shock or injury, do not expose this unit to
rain or moisture. Do not remove the chassis from its cabinet, or remove metal covering
from chassis parts. Removing the chassis from its cabinet exposes extremely dangerous high voltages. There are no user-serviceable parts inside. Hazardous voltages are
present inside the chassis. Refer all servicing to qualified personnel.
CAUTION: Never modify the power cord. If original power cord becomes damaged,
frayed, or has exposed wires, replace immediately with same rating and gauge, or higher. Replacements are commercially available or you can contact Tech 21 directly.
WARNING: Attempting to repair this unit is not recommended and may void its
warranty. NOTE: In the U.S. and Canada, servicing is performed at factory only. In
other countries, please refer repairs to the local Tech 21 authorized distributor.

power cord to change fuse. Replace with similar type & same value.
Units with 100-120V: use 1A. Units with 220-240V: use 0.5A.
QUICK START INSTRUCTIONS
Get your VT Bass Rack up and running before reading the entire manual. But by not
reading the manual, you’ll miss out on getting the most out of your new investment!
1. Plug your instrument into the front panel Input jack (on the left side).
2. Connect either the 1/4” or XLR SansAmp Output to the input of your mixer, power
amp, powered monitor or amp.
3. Attach the AC cord to the unit and plug into a wall socket. Set the Level and XLR
controls to minimum, then turn the VT Bass Rack on and engage the SansAmp Switch.
4. Turn on the mixer or amp and bring up the Level or XLR controls of the VT Bass
Rack. If the signal is too “hot,” resulting in unwanted distortion, or too weak, check the
mixer’s or amp’s input control as well as the Level control of the VT Bass Rack.
5. Play your guitar and you should hear sound coming through your system. If not, check
that your guitar’s volume control is turned up, recheck your connections, and be sure your
cable isn’t faulty. If there is still no sound, refer to factory or qualified technician.
