Get to know them!

The popular SansAmp PSA-1 underwent an internal redesign and is now known as SansAmp PSA-1.1. While the 100% analog signal path and functionality remain the same, during the design process Tech 21 was able to include a few new features: an on/off switch on the front panel, more program locations (there are now 128), a master volume control, an XLR ground lift switch, phantom power MIDI input, and a dedicated headphone output.

Tech 21 SansAmp PSA-1.1 Amp/Cabinet Emulator at a Glance:
  • An updated version of a studio standard
  • Produces the most recognized tube amp sounds for guitar or bass
  • MIDI support allows loading and saving presets
  • Dual outputs can be used simultaneously

An updated version of a studio standard
The SansAmp PSA-1.1 is the newest version of the SansAmp PSA. 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 will find the SansAmp PSA-1.1 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 preamp, "monster direct box" to P.A. system, and as an outboard processor.

Via the SansAmp PSA-1.1's MIDI port, you can load and off-load your PSA-1.1 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 foot controller).

The PSA-1.1's 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.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
