In a time of every-other-month upgrades, the SansAmp PSA has been modified only once in 21 years, and primarily to add hardware features. This is a powerful testament to the unusual longevity of the SansAmp PSA. Combining a warm, all-analog signal path with digital recall, it offers 49 factory presets of the most recognized vintage and modern tube amp sounds for guitar and bass, and 77 user-definable locations.

Via MIDI, you can load and off-load presets, map program locations, and select MIDI channels (including Omni Mode). Remote program changes can also be made via MIDI (including Tech 21’s own equally player-friendly MIDI Mouse or MIDI Moose footcontrollers). Other features include dual 1/4” and XLR outputs for stereo processing, either of which can be set at line or instrument level, and used simultaneously. The non-glare, 3-digit LED display is readable from any angle, in daylight or darkness.

Considered a staple in professional recording studios, the SansAmp PSA has been used on major releases and worldwide tours for multiple applications and instruments, including horns, vocals and drums. Players, engineers and producers alike find the SansAmp PSA very simple to operate. To program, you just tweak the knobs and save. Parameters are adjusted in real time with traditional analog potentiometers. The digital memory stores the positions of the pots. With 256 incremental steps, each rotary control increases and decreases in a smooth linear fashion.

The exceptionally versatile SansAmp PSA-1.1 offers 49 factory presets of the most recognized vintage and modern tube amp sounds for guitar and bass, and 77 user-definable locations. A Universal Output Section enables the signal to be compatible with full range systems as well as guitar/bass speaker cabinets. With the SansAmp PSA-1.1, you can record direct to tape, as well as warm up existing tracks in mixdowns. For live applications, it can be used as a pre-amp, “monster direct box” to P.A. system, and as an outboard processor.
