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 per-

forming live, and created an entirely new category of signal processing.

There have since been many entries into this niche, yet SansAmp contin-

ues 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

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

Originally introduced in 1993, the SansAmp PSA-1 rackmount, and later

PSA-1.1, quickly became studio staples.  The SansAmp PSA has been

used on thousands of major releases, worldwide tours and film sound-

tracks for multiple applications and instruments --including horns, vo-

cals, and drums. 

Sadly, necessity forced retirement from production, as certain key parts

were no longer available. We realized this was an opportunity not only

to redesign it, but to streamline its architecture into a pedal. 

The SansAmp PSA 2.0 offers the same 100% analog circuitry for

punchy, responsive, organic sounds that bring out the best in any instru-

ment.  Only the programming and memory sections are digital. It also

offers the same essential functionality and versatility.

In the studio, you can record direct, enhance existing tracks in mixdowns, as

well as add interesting touches to any instrument. Live, the SansAmp PSA 2.0

can be used as a pre-amp direct into a power amp with guitar or bass speaker

cabinets, as a “monster direct box” to a P.A. system (or both simultaneously),

and as an outboard processor.  Additionally, the PSA 2.0 features a Perform-

ance Mode, which turns it into a 3-channel stompbox.

The SansAmp PSA includes MIDI capability for calling up programs and storing

program data. There are 49 factory presets and 77 memory locations to store

your own custom sounds, plus two bypass programs. When you switch be-

tween programs, there is no lag time, or “cutting out.”

The controls work very much like those found on a sophisticated amp. You

don’t need any special training or a degree in physics to operate your unit. Stor-

ing and recalling programs is simple:  set your tones and push the Save button.

When you turn a knob, you hear the difference immediately --in real time. The

rotation of each control increases and decreases in a smooth, gradual, linear

fashion.

The SansAmp PSA 2.0 is designed to provide you with the flexibility to find al-

most any conceivable tonal personality within the tube amplifier sound spec-

trum.
