      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      This preamp is genius. I have taken this preamp over the top-of-the-line Engl and Mesa Triaxis.

      Essentially, this preamp provides you with a rack mountable pedal of your dreams. You can add variable amounts of preamp distortion and poweramp saturation while also adjusting lo/mid/highs.

      You get a stereo effects loop and MIDI presets. Plus it is reasonably priced.

      Great tone, great unit

      By cmcblues

      from San Antonio, TX

      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      Overall, I couldn't ask more from this unit. It delivers exactly what it claims. When paired with a high-quality effects unit and power amp, you've got an unbelievably versatile rack rig that would be tough to duplicate. My brother tried to convince me to get an all-in-one unit (Boss GT-10, ElevenRack) and I just didn't want that. Invariably you lose control over the tweakability of your sounds. Having everything separate just makes a world of difference to me. Plus, if one unit fails, it doesn't mean your whole rig is blown (try getting stranded without an amp on the road if your Marshall/Mesa/Fender tube amp blows and you don't have a backup or money for repair). This thing focuses on creating great tones and it delivers. It also seems able to pack it in for the long haul. I'm never getting rid of this thing.
      Aside from everything being analog in this little unit, there aren't many "features" to speak of other than the fact this thing goes from super clean to uber-distorted very easily and with great versatility. It does have several routing options that are nice (1/4" and XLR ins and outs) as well as being MIDI-switchable make this a perfect, no-frills rack pre. I had previously read reviews that mentioned running this unit either direct into a PA for live use (or using full range speakers in general-which isn't feasible for me because I like my 4x12 with Vintage 30's) or using a solid state power amp to power the unit. I can vouch for the power amp. I first tried it with a tube power amp and even though it sounded awesome and a tad bit warmer than the solid state, it did lack the punch that I would imagine you'd miss if you're used to your cab smacking you in the back while you play. So I use mine with a 1 space rack Carvin DCM200L (4 lbs!!, 200 watts). I run this on ONE channel (my rig is mono) and it's PLENTY of power and punch. This goes through an Avatar 4x12 with Vin 30's. Sounds amazing. My band mics everything down anyway so it still goes through the PA. Effects loop works great and has different setup options for it and the unit as a whole can be run stereo, which I have yet to try but imagine it would be just as good as the mono signal I run.

      This unit works great for direct recording as well. My bass player and I used it to re-record some overdubs for my bands album direct into my Presonus Firestudio Project. The direct guitar sounds are great, but be careful how much gain you use. The patch that I'd programmed for live use didn't sit so well direct in. It was too much gain and it sounded fizzy (my fault, not the unit's fault). If you're going direct in and you'll be overdubbing tracks anyway, you should turn the gain down especially with multiple guitar tracks. The clean patch I'd programmed was WONDERFUL and the engineer liked it so much he used it in our final mixes with little to no additional processing. We ran the bass through the SVT preset with almost no tweaking (I think I only adjusted the volume) and it sounded huge and fat with that great Ampeg grit.
      So far, so good. Been touring with this for about 6 months or more with zero issues. Integrates well MIDI-wise with my G-Major 2 effects unit and once you get all the MIDI mapping and programming down, it's a cinch. It is safely housed in my 8-space rack unit but my rack spends its touring time either in the trailer or on stage, otherwise it's at my house. Works great regardless of where it has been.
      I do think this unit is a bit pricey but you know, you totally get what you pay for. I'm a firm believer in this. Where this unit is a bit more than I wanted to spend initially the investment was totally worth it. The tones this unit produces can't be reproduced without investing thousands in the amps that it claims to model (even though this isn't a modeler). I have a Marshall Plexi and have played the Bluesbreaker and those 2 models get so close, I can hardly tell the difference. The Fender models get very close as well (Champ and Twin). There is a lot of tweaking available in this piece and tones galore. Just spend some time with it and start with a preset that's a close to the sound you want and tweak from there. If you're a bit inventive you can create your own signature sound on this with some patience in learning what each knob does. Read the manual on this.

      It's a great guitar preamp

      By Anonymous

      from Undisclosed

      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      I don't know why this is listed under BASS products. Although it does have frequency response to handle bass and has several presets that are great for bass, it is first-and-foremost a guitar preamp; one of the best preamps you will ever hear.My original PSA is almost twenty years old and it still works perfectly. It's been in and out of racks, rained on, frozen, baked in hot trunks, shipped overseas and back a dozen times. It's never let me down. I got a new one just because I wanted a spare.Why MF doesn't put this under the GUITAR category is a mystery.It certainly is the most versatile raw guitar preamp available.No effects. Just great tones.Easy to edit and store ( one button )Lightweight. Works well with numerous power amps. I plug this into two 2x10" cabs for stereo ( with a TC chorus) powered by a QSC 300 watt amp. I can get great authentic Marshal distortion at low volumes, but I can also rip heads at twenty paces.It not only sounds like tube-amps, it BEHAVES like a tube amp.If you know how to use your guitar's volume knob, this is the old-school feel you want.I have never needed repair to my PSA preamps, or any other sansamp products despite decades of heavy use. But I have spoken to tech 21 for advice and technical support. They are real guys, easy to reach by phone, and they know their toys inside and out. That's because they actually make them here in the USA instead of outsourcing to the Asian rim.If you have experienced real tube amps as much as I have, you will appreciate the Sansamp product line. This is their flagship rack mount version. It can send phantom power to a midi foot-controller through the midi cable, so you don't need a wall-wart power supply. I use a cheap Rolls midi foot-control, but sansamp makes two great midi FCs that are reasonably priced. If you want all the great guitar tones, AND you need midi switchable control, this is the ticket. It completely rocks.

      Forget the Modelers

      By ATGuitarist

      from Undisclosed

      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      No, it doesn't have a gazillion effects. Neither does it have a slick software interface. There's no USB. It does one thing and one thing well - serve up great tones for guitar, bass, and even vocals.But the ANALOG, Mosfet circuitry of the PSA-1.1 gives it the edge over any digital amp modeler. I am running mine through a tubepower amp and the tone has impressed guys using all tube heads as well as modeling preamps. It will do everything from super clean to full on raging metal gain. The controls take some getting used to but really allow for some majr tweakablility. Does it sound exactly like a Dual Rectifier, Plexi, or Twin? No but it'll get you VERY close. It actually emulates the characteristics of these amps but still has a character all its own.After 20 years of playing this unit provided me the tones I heard in my head and could never find in other amps or effects units. I've owned.

      Magical rack preamp

      By Mac-c2-8i

      from Indiana

      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      Have owned several preamps, including other tech 21 products (tri od, prog. bass driver, para driver). This one is the mother of all. I have lost the need for the tri od and bass driver and solely use this and para driver for all guitar and bass needs. Mostly play bass (fender jazz) and the 10 presets are great- only need minor tweaking for your preferences and save in the memory. For guitar, I love how the Fender clean models react to strat single coils and how marshall and mesa sounds react to humbuckers. I must admit I use an MI audio overdrive very lightly to warm up the clean settings. You could probably just tweak knobs to get that effect, but I just find it easier to use the pedal. I have found the effects loop sounds best for me in the 50/50 mode where it blends dry and effect equally. Delay and modulation sounds very natural this way and preserves your sound better. Also, there are 2 returns on the loop for running stereo. Sounds are amazing and versatile for a "non tube" product. I buy and sell alot of stuff, but this one's here to stay.I use the midi mouse to access patches. It works smoothly as well.

      Great for Guitar too!

      By Tech21Fanboi

      from Deep South

      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      I recently purchased a PSA 1.1 that I'm using into a PA (FRFR) set-up. This thing rocks, I can go from pristine cleans with Marshall, Fender or Mesa tones, to overdrive to full saturation while controlling the distortion/harmonics at the frequency bands; while mid control would be great, the active Low and High settings when lowered push up the mids. I AB'd some of the presets with their namesakes on youtube and recordings where consensus has the artist using the modeled amp. One example is the bluesbreaker - near spot on to what Clapton had, and there are more examples.Analog dynamics too, you can dial in the feel and dynamics too. I also have a few Character Series pedals, and combined they cover a wide range of tones in a small foot print, now I'm upgrading my effects

      Sansamp PSA 1.1 Is The Best

      By redcoat52

      from Tofino Canada

      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      This one tops all the preamps I've owned. The versatility is top notch. I've connected a Sansamp RPM to this unit. I now have the perfect electric and acoustic guitar setup all in one package (add radial cabbone and power amp) The price is right and midi, well, there's no limit to what you can do.

      Great!

      By thelatenessmonster

      from Boston, MA

      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      I had used the original version a few times before to great effect, now I have this one in my studio rack and have put it through it's paces. Works great on direct guitars, especially for tight high gain rhythm mesa/marshall emulations. Can be a stunning surprise on electric bass DI, big warm Ampeg-like drive sounds jump out. I take XLR outs into line ins on a UA 2-610 preamp into my DAW and get fat warm "vintage-modern" tones. It has some character all it's own. I have used this for vocals, adding some heavy aggression to drums, etc. It adds this great edge and crunch to variety of sources. Tech 21 got it right, this is the great workhorse of emulation.

      Absolute killer

      By PipeMaster

      from Washington DC

      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      I have used Tech 21 equipment in the past - mainly the TriAC - but the PSA 1.1 might be the best piece of sound gear ever. Start with the presets and tweak away. Hooked to a Power Engine 60 (or 2 or 3 or...) its tone will absolutely kill for any style of music.

      Greatest Tone Ever Without Tubes

      By nuworldman

      from Virgina/New Jersey

      Comments about Tech 21 Sansamp PSA1.1 Preamp:

      Sansamp has not only created magnificent tube tone emulation in this pre-amp. It also has it's own great sound at the same time. The PSA 1.1 gives you great sound for any genre of music with user friendly tweakability. No phony "digital" type sound.
