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 com-
mercially 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 con-
tinues 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 deliver-
ing consistent quality sound, studio to studio, club to club, arena to arena.
PRODUCT OVERVIEW
When you want to fatten your tone, increase sustain and punch up your sound, a
compressor is a way to go. But compressors can dredge up feelings of compro-
mise, confusion, frustration and intimidation. So we set out to make a player-
friendly pedal utilizing old school, all-analog, FET-based technology, which is
inherently warmer, more transparent, and more musical than other methods.
Designed specifically for guitar and bass players, the Boost COMP offers simplified,
useful
controls --controls that are not normally found on compressors. Most com-
pressors have a singular function or are engineered for studios and full-range sys-
tems. The Boost COMP uniquely gives you pre- and post- tone shaping adjustability
to get the right balance that complements your instrument and playing style.
When it’s time to jump out, a powerful boost function delivers up to 21dB of clean
boost to increase your output level --without adding more compression. A true
post-boost, this function can also be used independently.
Uncomplicated means less stress and more focus on your playing. Get vintage
warmth, dynamics and sustain the easy way with the Boost COMP.
APPLICATIONS and CONTROLS
Use with any amp --tube or solid state, vintage or modern. NOTE: You can also
achieve the same results using the Boost COMP in conjunction with any model of
our own SansAmp™ Tube Amplifier Emulators.
PRESENCE:
As compressors typically darken your guitar signal, the Presence
control provides a pre-compression tonal boost in the frequency range of 2-3 kHz
to preserve high-end string attack and clarity.
COMPRESSION:
A single, continuously variable control to dial in just the
right amount of compression you need. A little goes a long way, from soft and
barely noticeable to super squashy, infinite sustain.
TONE:
Tone provides a post-compression cut or boost to generate a mel-
lower, more lush tone without getting too dark. This very musical, specialized tone
control will cut or boost 12dB of your high end.
LEVEL:
Adjusts the output level of the unit.
BOOST:
Adds up to 21dB of clean boost. The Boost function is a true post-
boost to kick up the volume without adding any further compression. Activated via
its own footswitch, it can also be used independently from the effect.
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, so be sure to unplug
when not in use.
1/4” OUTPUT:
1kOhm low impedance output drives long cables without loss
of signal integrity, even in bypass.
