Tone-shaping Beast

When Tech 21 originally released the rackmount SansAmp PSA-1 in 1993, it quickly became an indispensable studio and stage staple — and a favorite here at Sweetwater. It was deployed on countless recordings, worldwide tours, and film soundtracks for multiple applications and instruments, including drums, horns, and even vocals. Unfortunately, as certain key components became unavailable, Tech 21 was forced to retire it. They quickly realized, however, that this sad occasion also presented an opportunity not only to redesign the SansAmp PSA — but to streamline its technology into a pedal. Meet the SansAmp PSA 2.0. It has the same all-analog circuitry (only the programming and memory sections are digital) to deliver punchy, responsive, organic sounds that make any source sound its best. The SansAmp PSA 2.0 provides the same functionality, ease of use, and amazing versatility as its esteemed predecessor.

What the SansAmp can do for you

In the studio, you can use the SansAmp PSA 2.0 to record direct, to spruce up your tracks in mixdown, and to add dimension to any source. Onstage, you can use it as a preamp (plugged, for instance, into a power amp connected to a guitar or bass cab), as an incredible-sounding DI routed directly into a PA system, or as a characterful outboard processor. In addition, the SansAmp PSA 2.0 features a Performance Mode, which turns it into a 3-channel stompbox! As millions of musicians have found, the Tech 21 SansAmp is a tone-shaping beast — your do-it-all DI, preamp, EQ, drive, crunch, and punch machine.

Nail any tube amp character, fast

Tech 21 designed the SansAmp PSA 2.0 with functionality similar to a high-end amp, which means you don’t need an engineering degree to operate it. Storing and recalling programs is easy: craft your tone and push the Save button. When you turn a knob, you’ll immediately hear the difference in real time. The rotation of each control increases and decreases in a smooth, gradual, and linear fashion. The unit has 49 factory presets and 77 memory locations to store your own sounds, plus two bypass programs. And when switching between programs, there is no cutting out or lag time. The SansAmp PSA 2.0 gives you the flexibility to nail almost any tube amp tonal character you can dream up.

Tech 21 SansAmp PSA 2.0 Features:

  • 100% analog signal path; digital programmability
  • Performance Mode to instantly access your 3 most often used presets
  • Buzz, Punch, Crunch, and Drive controls for tons of tonality options

Awesome Analog Amp Pedal
If you're looking for an outstanding analog amp pedal, the SansAmp PSA 2.0 is for you!
I selected this over a digital modeling amp pedal as I wanted good solid tone and simplicity, and didn't need built in f/x and dozens or hundreds of presets.
SIMPLIFY and focus on tone and playing was my goal!!

My top reasons to buy this product:

1) Easy to use. Functions like a "real" amp by adjusting the knobs to find your tone rather than selecting an exact amp and building as done with digital modelers. It's a journey to find that tone that fits who you are and what you're playing.

2)Also has the playing feel like a tube amp. Responsive to subtleties in playing resulting in expressive playing experience.

3) Despite the simplicity, has plenty of variety both in amp types and adjustment for clean/overdrive and EQ. Right now I'm favoring more of a British amp sound, so I used the factory Marshall and Vox presets as a starting point and customized to presets to my liking.

4) Perhaps my favorite feature is the DRIVE knob. This adjusts the power amp saturation rather than the pre-amp section. Most of my presets are built around using the drive knob for various power amp saturation. I love the responsiveness of power amp tubes when pushed slightly for varying degrees of sweet breakup.

I also got the Tech21 MIDI Mongoose pedal to have more preset access. Currently, I'm using only the first 5 and that's all I need right now. Easy to add more if/when needed.

See my pedal board photo with everything in place. It's a mix of analog and digital pedals that augment the PSA 2.0 where needed. It all starts with the wonderful rich and authentic tones from the PSA 2.0.
Currently running direct into a PA.
Awesome
I own many Tech21 products, and they are all great. The PSA 2.0 is yet another great device made by Tech21. This pedal allows me to get rid of some of the expensive overdrive pedals that I've purchased over the years. I use this as a preamp for my 15W Magnatone Varsity, and it sounds so good! I highly recommend this pedal. A built-in tuner would make it even more perfect. I would like to see Tech21 integrate the PSA 2.0 into a FlyRig pedal, which would be practically everything a guitarist would need.
tech 21 PSA 2.0
I just kind of stumbled on this. Was thinking of getting a sans amp. This thing sounds great. The presets are very usable. Also plenty of storage for new presets. Very simple to use. Great tones. I am completely rearranging my pedal board to get this sweet sounding piece in the mix. Very satisfied.
It rocks!!
I bought mine
circa 2020. I use it in both live and studio applications. Their is NOT any amp tone you cant get from this monster!! I use it now with a new ZOOM G5n (for effects), and into the PSA 2.0.. Then, into a HEADRUSH
1x12 FRFR cabinet. Absolute tonal bliss no matter which of my guitars I use!!
This pedal ROCKS!!
Music background: Gigging semi-pro with 47 yrs. of playing under my belt.
I love it so much, I bought two!
You can buy a boatload of boutique dirt pedals, or just buy one of these. The midi control, and 120 spaces allow for just about any guitar or bass tone you can dream up. The cab sim is awesome, and you can use it with a power amp and speaker cab with the sim on and it doesn't make your cabinet sound like it has a blanket over it. Just awesome. So now my two pedal boards (one is a backup) have a Mr Crybaby, a boss MS3, a TC electronic cab sim pedal for the internal boss distortions, and a DI for going direct into a board. It's all I need. I play guitar, bass and keys, and all I need is a small mixer and a my full range monitors and I can do any job or session that comes up.
Music background: I'm old, and actually play instruments
