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 made his 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.There have since been many entries into this niche, yet
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 B.Andrew Barta 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 quality sound, studio to studio, club to club, arena to arena.
PRODUCT OVERVIEW
The Character Series pedals are unusual inside as well as out.They have an abundance of knob controls, are easy to use, and feature our proprietary,100% analog SansAmp technology.These multifunction pedals can be used as a stomp box with a guitar amp, as a pre-amp to drive a power amp,
and for recording straight into a mixer or computer.
You can explore and tailor various eras within each amp style simply by turning a knob.A single,
continuously-variable Character control sweeps through an entire tonal range that spans decades
of sounds.The Character and Mid controls and speaker simulation are individually voiced and custom-tuned to reflect the specific personality traits inherent in each amp style.
By engineering individual amplifier styles, the Character Series pedals offer a significant value at a nominal price.Whether you’re frugal or extravagant, you can focus on just those that are your personal
faves.Choose one, two, or collect them all --and trade them with your friends!
APPLICATIONS
AS A STOMPBOX with a guitar amp.You can connect the Character Series pedals in-
line just as you would a standard distortion or overdrive pedal. If the pre-amp of your guitar
amplifier is imparting too much of its own character on the pedal, plug into the low level input
and set the pre-amp as clean and neutral as possible. Since most amps tend to be on the bright
side, you may need to start with High below 12 o’clock and then adjust as necessary.You can also
plug the pedal into the effects loop return (if the amp has one).This will disable the entire preamp of the amplifier allowing you to hear a truer representation of the sound.NOTE: the master
volume on your amplifier will be defeated, so be sure to have the volume control down on the
pedal.
AS A PRE-AMP driving a power amp. The 1/4” output of the Character pedal has
enough juice to drive a standard power amplifier. Simply connect the 1/4” output to the power
amp input and adjust the Level control accordingly.You will probably not use the bypass mode of the
pedal in this setup.
AS A DIRECT RECORDING DEVICE into mixer or computer.All of the tone shap-
ing and cabinet emulation needed is already incorporated into the pedal, giving you the perfect
sound “right out of the box.” The Character Series pedals automatically convert your guitar signal
to Low Z allowing you to plug into a variety of inputs that would normally load down your guitar’s signal.These pedals can be plugged into mixers (live and studio), workstation/recorders, and
even directly into the sound card on a computer.
THE INS AND OUTS
1/4” INPUT: 1megOhm instrument level. For normal operation, signal level to Input should be
close to that of a standard electric guitar (approx -10dBm / 250mV).The input is designed with
the same sensitivity and loading characteristic as a tube amp.Also switches battery power on/off.
To avoid battery drain, unplug when unit is not in use.
!! WARNING !! DO NOT RUN THE SPEAKER OUTPUT
OF ANY AMP directly into a SansAmp input.
Severe damage to the amp and the SansAmp will result.
1/4” UNIVERSAL OUTPUT: Unbalanced 1kOhm Low Z output.This output can be con-
nected to High Z guitar amplifiers (or effects) as well as Low Z mixer and computer inputs.Output
level is unity gain when pedal is in bypass mode.When activated, the output level can range from instrument level to line level depending on your settings.Also drives long cables without loss of signal
integrity,even in bypass.
GUIDE TO CONTROLS
LEVEL: Adjusts the output level of the unit.This control has an exceptionally wide range for
maximum compatibility with a variety of equipment.
LOW, HIGH, MID: On-board post-EQ section gives you full control, like having a studio mix-
ing board at your fingertips. Unlike passive tone controls that only cut, these active controls cut
and boost ±12dB. Low is tuned to 125 Hz; High frequency is 3.2 kHz.Mid is custom tuned for each
model.*
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*: Voiced differently for each pedal in the series. It sweeps through various
tonal possibilities associated with each style of amplifier. In addition to modifying the frequency
response, Character also influences the attack and drive characteristic of each particular amplifier
style. Therefore, you may need to adjust your gain and tone settings after tweaking the Character
control.
SPEAKER SIMULATION*
Built in speaker simulation is an integral part of the Character Series circuitry. Each model is
tuned to match the speaker/cabinet of that amplifier. 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.There is no need to defeat the speaker simulation circuit
when using it with a guitar amplifier.The speaker simulation works in tandem with the EQ controls to custom tailor the overall sound.
*For more details and sample settings,
see separate charts specific to each model.

Settings below 12 o’clock are in the Black and
Silver Face family. When clean, there's a soft
midrange with a nice top-end sparkle. Driven,
the tone moves to a warmer low-end breakup.
Around 12 o’clock brings you into Blonde
territory with more of everything --more lows,
more mids and more highs.
Above 12 o’clock moves things into the
Tw e ed era with a pronounced midrange bark.
Full up gives you lead boosted tones.

considered “normal.” So you need not set everything at max to get maximum results. For instance,
to brighten your sound, rather than automatically boosting High all the way up, try cutting back on
Low first.
2) To find the best settings for interacting with your other gear,you may need to use radically
different settings for each individual way you use it.You need not be discouraged or suspect something is wrong with the unit. If you’ve got your sound, you’ve simply found the right balance to complement each individual piece of gear.We recommend you start with the tone controls at 12
o’clock and cut or boost as necessary.
3) Tech 21 pedals have exceptionally low noise levels. However, they may amplify noise
emanating from the input source.To minimize noise, we recommend active electronic instruments
have the volume set at unity gain/maximum and tone controls positioned flat. If you need to
boost, do so slowly and sparingly.Also check for pickup interference by moving your guitar or
turning the volume off. Be aware single coil pickups are more likely to generate noise.
4) Placement notes: Each of the Character Series pedals can be treated as an amplifier or preamp when it comes to setting up your signal chain:
Place the following effects BEFORE the Character Series pedal:
Booster, Compression, Fuzz, Phaser/Vibe, Overdrive,Wah.
Place the following effects AFTER the Character Series pedal:
Delay, EQ, Flanger, Phaser (yes, after is good, too), Pitch Shifter,Reverb.
5) Buffered bypass eliminates the shortcomings associated with “true bypass” (pops and clicks,
and high-end loss when multiple pedals are connected together), as well as signal loss associated
with other types of switching circuits.
6) Custom actuators. All Tech 21 pedals feature smooth, silent-switching actuators that are
licensed by other major manufacturers.
7) LED indicator light. When battery begins running low (around 6 volts), the LED will
become noticeably dim.
