All-tube Design with Modeler Flexibility

Reap the rewards of responsive tube tone structures without sacrificing innovative digital modeler sensibility with the Synergy SYN-20IR. This unique head uses the same preamp docking technology found in Synergy’s other units, with one major exception — the tubes. Sporting a portable lunchbox head design, the SYN-20IR is loaded with dual EL84 power amp tubes that, coupled with a Synergy preamp module, create a 20-watt all-tube amplifier equally at home in the studio or on the road. The flexible tonal capabilities aim to create an analog modeling system loved by Sweetwater guitarists looking to sculpt their tone with the flexibility of modern digital rigs and raw tube tone. With one or more preamps, a built-in American-style clean channel, and selectable power amp structures, you’ll have three channels to explore any style from crisp clean to monstrous high gain. Once you’ve dialed it in, save your settings, accessing them via a 3-button MIDI footswitch. Transmit your signal using the customizable IR presets, with outputs for any cabinet and a built-in headphone jack for silent practice. With the SYN-20IR head, you no longer have to compromise analog tube performance for modern technological convenience.

Note: The SYN-20IR requires a Synergy preamp module (sold separately). Please contact your Sweetwater Sales Engineer with any questions.

Plug-and-play your favorite amps

Available separately, Synergy’s line of preamp modules provides everything you love about iconic amps with unrivaled accuracy in analog form. Each all-tube, 2-channel module is fully equipped with dual 12AX7s with preamp circuitry that matches the legendary amplifier it’s based on. With modules for various brands such as ENGL, Friedman, Peavey, and Morgan, Synergy goes to painstaking lengths to ensure each is represented in the most accurate way possible. This means you get all the features and benefits of each in a form factor that is easily stored and swapped, thanks to the compact size and thumbscrew fastening.

More than a power amp

With a healthy balance of power at 20 watts, the EL84-powered SYN-20IR is effortlessly portable, durable, and endlessly capable. Assign one of three analog power structures to each channel, then layer on one of several built-in IRs, load your own, or run out to your favorite cab. The structures help optimize the amp to whichever preamp is loaded up, altering the contour and feel to the module's tonal needs. Mode A offers a clear yet punchy sound, B provides relaxed mids and bright high end, and C allows for a tight modern feel. Plus, with industry-leading low-latency IR technology built in, you can forgo heavy cabinets in favor of preset or user-loaded IRs run out via a balanced XLR output right on the amp. Use the editor software to dial in the perfect tone and load it right to the head via the USB connection on the back.

Synergy: a tube-fueled alliance

Merriam-Webster defines synergy as "a mutually advantageous conjunction or compatibility of distinct business participants." With Synergy Amplification's assemblage of tube-amp talents such as Dave Friedman (Friedman), Joe Morgan (Morgan), Steven Fryette (Fryette and VHT), Mike Soldano (Soldano), and Peter Diezel (Diezel), the name is a perfect fit. Each product is painstakingly crafted by these titans of the tube-amp world, ensuring every nuance of their legendary amplifiers is translated to your tone. For the most iconic tones in the most convenient package possible, Sweetwater is proud to offer you Synergy Amplification.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Reviews

Synergize me!
Great sounding little amp.
It does have plenty of output for a 20watt head.
Max Rapp my Sales Engineer was very helpful in recommending this Amp!
Thank you!
This was this missing link from Synergy!
I started using Synergy gear shortly after their debut several years ago. I have a SYN-2 rack mount chassis and just shy of a dozen modules, and while the SYN-2 is still very much a great piece of gear, I paradoxically found that having two slots was more of a hinderance than a help in my particular case. For me it meant having to set up presets on my pedalboard that accommodated whatever combination of 2 preamp modules I'd likely have in the chassis. It made it an over-complicated hassle, even if it sounded great.

Enter the SYN-20IR. One slot is perfect! The built in clean channel is really quite good, the power amp profiles are a great feature, and of course the IR capabilities make it a powerful tool for both stage and studio. Even if I'm programming in specific presets in my pedalboard for each preamp module, the complexity of different combinations is gone. And with every preamp module I've got a powerful three channel amp. This little guy is a re-amper's dream rig.

I've attached a video from a performance on StageIt using the SYN-20IR with the Soldano SLO-II module and delay + reverb provided by Fractal FM9.

Simply Amazing!
I owned a local recording studio for 25 years and it feels like I've heard every amp and pedal out there, but The Synergy system with the SYN 20IR is so impressive! I love amps. I love modelers, and I still use all of them but Synergy is the best of both worlds. Covienence and real tube amp sound.
It's very easy to use your own IR's. The IR's that come with it are very good but I use York Audio IR's with it.
Lots of tone shaping capabilities with the 20IR! I bought the Soldano and the Friedman DLX and they both are simply amazing. Bogner is up next!

The perfect hybrid solution
Like many others, I come from the floor modeler realm but wanted something with a better response/feel and I didn't need a million options to constantly scroll through and edit. Enter the Synergy amp.

With its IR and XLR output, it's perfect for my church gig. It's built like a tank. It's not heavy but it's got some heft to it for a lunchbox-sized amp. I love having the tactile feel of knobs with immediate aural feedback instead of diving through menus...it's great to have a real amp again!

To start with I purchased the Marshall JMP and the Synergy IICP modules and I'm ecstatic with both! I run a Friedman 2x12 vertical slant cab for monitoring and I'm getting the best tones I've ever had.

Oh yeah this sucker is LOUD, too. Running the master volume at 1 (or slightly lower) is plenty for me to monitor myself over the drummer.

Synergy SYN-20IR
After viewing several reviews of the Synergy SYN-20IR, I purchased the amp, with a module, from Sweetwater. The amp is killer. It has a great clean channel and the Fortin Killer Kali module sounds fantastic. I have Fender, EVH, Friedman and Vai/Carvin amps, and this stays right with them, plus it has the 'Reactance' control and built-in IRs that sound great. A winner all the way.
As usual Alden @ Sweetwater was very helpful and ensure my order was quickly on its way. Extremely satisfied.
