QUICK START AND STOP INSTRUCTIONS
QUICK START: Here’s how to get your VT Bass 500 up and running before reading
the entire manual. Note: By not reading the manual, you’ll miss out on how to get the
most out of your new investment!
1. Plug the VT Bass 500 head into speaker cabinet(s). If you’re not using Tech 21’s
B112-VTs, use cabinets rated for minimum of 500W RMS at 4Ω or 300W RMS at 8Ω.
2. Attach the AC cord to the amp and plug into a wall socket.
3. Plug your instrument into the front panel Input jack (on the left side).
4. Make sure the Level control is turned down. Then turn on the VT Bass 500 and
adjust the Level control accordingly.
5. Play your bass and you should hear a sound coming through the amp. 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.
QUICK STOP: After shutting off the VT Bass 500 (or any amplifier), wait at least 10
seconds before turning it back on.

Tech 21, the Company
Tech 21, Inc., was formed by a guitarist possessing the unusual combination
of a trained ear and electronics expertise. In 1989, B. Andrew Barta incorpo-
rated Tech 21 and made his unique invention commercially available to play-
ers and studios around the world. His highly-acclaimed SansAmp™ pio-
neered Tube Amplifier Emulation in professional applications for recording
direct and performing live, and created an entirely new category of signal pro-
cessing. 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. 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.

VT Bass 500, an Overview
The VT Bass 500 is a 500-Watt bass amp head with an all-analog
SansAmp™ pre-amp and Class D power amp. Formulated with the
same proprietary technology as our SansAmp Character Series VT Bass
pedals, the VT Bass 500 offers vintage and modern bass tones, ranging from
clean to thick flip-top funk, from indie rock snarl to deep tectonic distortion.
The unique, continuously-variable Character control moves seamlessly
between decades of different voicings. It alters the entire sonic structure of
the sound to achieve some of the most distinctive bass amp tones on the
planet.
Drive adjusts the overall amount of gain and overdrive, similar to when the
output of a tube amp is being pushed. A Blend control allows you to blend
the direct instrument signal with the SansAmp Tube Amplifier Emulation cir-
cuitry. The Bite switch activates a presence boost, which tightens up the
sound when you are in distorted settings. It also adds definition to your
notes when the Drive is set for cleaner tones.
For studio and live applications, our proprietary, 100% analog SansAmp
Tube Amplifier Emulation technology enables you to go straight into the
mixer of a recorder or PA system via the LR Direct Output.
The VT Bass 500 offers bootylicious tones for fearless pro players yearning
to jump ship from the status quo.

FRONT PANEL
INPUT JACK
Faithful to the original designs of traditional tube amplifiers, this piezo-friendly 1/4" Input
is high impedance 4.7 MΩ. The typically additional low sensitivity input, however, is not
needed due to the Pad switch. When the Pad switch is engaged, the input changes to
low impedance, approx 10 KΩ, which helps decrease line noise interference and pro-
tects the pre-amp from being overloaded by high output, active pickups.
PAD SWITCH
For active basses and cleaner tones, there is a -10dB Pad switch. To engage, push the
switch in.
GUIDE TO CONTROLS
DRIVE
Adjusts the overall amount of gain and overdrive, similar to when the output section
of a tube amp is being pushed. The first half of the rotation will increase the volume
as well as the overdrive.
CHARACTER
Sweeps through an entire range of tonal possibilities. In addition to modifying the fre-
quency response, the Character control also influences attack and drive. Therefore,
you may need to adjust your gain and tone settings after tweaking the Character control.
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 vintage and modern distorted bass tones.
MID, LOW and HIGH
The VT Bass 500 is designed with active controls, which boost and cut, rather than
traditional passive controls which only cut. This effectively doubles many of the con-
trol’s capabilities, giving you a much larger range of adjustability and, ultimately,
more variety. It should be noted that you need not necessarily set everything at max
to achieve maximum results. As you experiment and become familiar with the interre-
lationship of the controls, you’ll easily be able to customize your own sounds.
The tone controls cut or boost ±18dB from unity gain (12 o’clock). Low is tuned to
55 Hz; High frequency is 3 kHz; Mid is selectable between 500 Hz (with the Shift
switch in the in position) and 1K (with the Shift switch in the out position).
9
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 (affecting Drive, Character and Bite).
However, the Mid, Low, High, Level and input Pad remain active.
LEVEL
Acts as a master volume and is interactive with the Drive control. For clean sounds,
set Level at max and control the overall level with the Drive control. For dirty sounds,
use Drive to set up the overall amount of distortion and Level for the overall output.
BITE SWITCH
Engaged (in position), Bite activates a presence boost. This tightens up the sound
when you are in distorted settings and adds definition to your notes in cleaner set-
tings (when Drive is set below 12 o’clock).
LOOP SWITCH
Engages when the switch is in the in position.
SEND and RECEIVE (Effects Loop)
1/4” Send unbalanced line-level output; 1/4” Receive unbalanced line-level input.
HEADPHONE
1/4” headphone output. Mutes the power amp. NOTE: For best results, we recom-
mend using stereo headphones rated at 32Ω. Otherwise, performance may be com-
promised by efficiency loss. Also be sure the Level control is turned down to reduce
the risk of hearing damage.
10

SansAmp XLR DI Out
For recording, the SansAmp LR output is like having a built-in direct box. You can
go direct to the board and get the same sound you hear coming out of the speakers
right onto tape or disc. The SansAmp circuitry not only captures the warm, rich, nat-
ural harmonics and sweet overdrive characteristics inherent to tube amplifiers, its
speaker emulation encompasses all aspects of multiply-miked tube amp rigs.
For live gigs, you can use this output direct into the PA system and you won’t need
a microphone in front of the amp. And you won’t have to subject the audience to ster-
ile, muddy, or boomy bass tones that are associated with typical direct boxes.
XLR Pad Switch
Allows you to connect the VT Bass 500 via the LR Output to other equipment with
different input level requirements:
0dB (out position): Line-level output.
-20dB (in position): Pads down the line-level signal by 20dB.
Ground Lift
Connects or disconnects the ground circuits between the LR Output of the amp and
the mixer. We recommend starting with the ground lifted. If necessary, connect the
ground by pushing the button in.
USE WITH ACTIVE BASSES
Active electronics have higher output and typically generate more noise. To compen-
sate, we recommend engaging the input Pad. Additionally, experiment with using flat
EQ settings on your instrument and/or decreasing the Drive, Character and High
controls.
REAR PANEL
FUSE
Replace with similar type and same value:
100V - 120V units: use T 6.3 A
220V - 240V units: use T 3.15A
IMPORTANT REMINDER: Fuse holder located inside A/C cord receptacle. You
must disconnect and remove power cord to change fuse.
WORLDWIDE POWER SUPPLY
The VT Bass 500 can be operated on voltages ranging from 100-250VAC,
50/60 Hz. Be sure the voltage selector switch is set in the correct position
to match the local AC Mains voltage before you plug in the AC power cord.
11
VOLTAGE SELECTOR SWITCH
Be sure the voltage selector switch is set in the correct position to match
the local AC Mains voltage BEFORE you plug in the AC power cord. Use a
flathead screwdriver to slide the switch to the proper position:
100-120V: to the LEFT
220-240V: to the RIGHT
THERMAL SPEED CONTROL FAN
The fan is thermally-controlled and will turn on automatically when needed.
In the event of overheating, there is a heat protection circuit which will
automatically shut down the unit. Normal operation will resume when the
heat dissipates. Note: direct sunlight may contribute to overheating.
NOTE: Be sure there is ventilation on all sides of the unit and the vent
openings on the sides, as well as the back, are not obstructed to
restrict the flow of air to the heatsinks.
SPEAKON®SPEAKER OUTPUTS
Wired in parallel. These high quality plugs lock securely to ensure maximum power
transfer and provide fool-proof connections.
Total minimum impedance: 4Ω. 500W RMS @ 4Ω; 300W RMS @ 8Ω.
NOTE: Due to the high power of the amp, we do not recommend using 1/4” jack
converters as they are not rated to handle 500W reliably. It could cause intermittent
signal and may damage either/both the amp and your speaker cabinet.
