Guitar Player Gear of the Year Pick 2020
Tech 21 SansAmp PSA 2.0

PSA 2.0

Originally introduced in rackmount format in 1993, the SansAmp PSA-1 and later PSA-1.1 quickly became studio staples. The SansAmp PSA has been used on thousands of major releases, worldwide tours and film soundtracks for multiple applications and instruments –including guitar, bass, horns, vocals, and drums.

Wanting to change things up a bit, we streamlined its architecture into a compact, easily portable pedal. The SansAmp PSA 2.0 offers the same 100% analog signal path for punchy, responsive, organic sounds that bring out the best in any instrument. Only the programming and memory sections are digital. It also offers the same operational simplicity, essential functionality and dizzying 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 Performance Mode, which turns it into a 3-channel stompbox.

With 128 memory locations, storing and recalling programs is simple. You don’t need any special training or a degree in physics to operate your unit. The rotation of each control increases and decreases in a smooth, gradual, linear fashion, so when you turn a knob, you hear the difference immediately –in real time. You just set your tones and push the Save button. There is no lag time, or “cutting out” when you switch between programs. And with all-analog circuitry, there is zero latency.

BUILT-IN SPEAKER/CAB SIM. The 100% analog SansAmp Tube Amplifier Emulation technology encompasses the entire signal chain, from pre-amp to power amp to speaker simulation. An integral part of the circuitry, the SansAmp speaker simulation will complement any type of guitar or bass speaker cabinet system. You can also place an external IR after a SansAmp to give additional flavor if you so desire. The SansAmp speaker sim is designed and individually tailored for a smooth, even response as would be achieved by a multiply-miked cabinet –without peaks, valleys, and notches associated with single miking and many IRs.

The SansAmp PSA 2.0 is designed to give you inspiration to be your most creative self. It provides the flexibility to find almost any conceivable personality within the vintage and modern guitar and bass amplifier sound spectrums, as well as an assortment of revered stompboxes. You can even create your own “Farshall” or “Mender.” Check out the Studio 21 video below to find out how.
