Vibe up your tone with killer reverb and tremolo effects

It doesn't get more old school than the awesome effects Supro loaded on the 1622RT Tremo-Verb combo guitar amp. When it comes to ambience, the 4-spring reverb pan delivers the tube-driven atmosphere that really fills out your sound with classic depth and dimension. Immediately following the reverb tank there's a power-tube tremolo circuit you can use to shake up your sound with an extra dose of warmth and wobble. At Sweetwater, we've played with countless vintage-style amps, and it just doesn't get better than this.

No off-the-shelf speakers for these vintage-style amps

Stock speakers simply wouldn't do for Supro amps such as the 1 x 10" 1622RT Tremo-Verb. That's why Supro teamed up with America's premier speaker manufacturer, Eminence, to develop a series of custom speakers that would bring the classic voice of these guitar amplifiers to life. This special Supro CR10 speaker starts off with an edge-wound voice coil and a ceramic magnet, which push an extremely lightweight and stiff paper cone. The result is a distinctly Jensen-esque tone with superb volume and exceptionally tight low end.

Supro - a brief history

Supro's roots can be traced back to the 1930s, when the National Resophonic and Dobro guitar companies merged to form a manufacturing entity called Valco. Valco manufactured Spanish acoustic guitars, metal-faced resonator guitars, and electric lap steel guitars under a variety of brand names, including Airline, Oahu, and National. They also designed amplifiers for several other companies such as Gretsch, Harmony, and Kay. It was during this time that Valco began producing guitars and amplifiers under the Supro name. Extremely popular amongst Southside Chicago blues musicians in the 1960s, Supro amplifiers proved equally popular with the British musicians who were influenced by them. By the late 1960s, notable guitarists ranging from Jimi Hendrix to Albert Lee to Jimmy Page were seen playing Supro amplifiers. Original Supro amps often sell for premium prices on the used market because of their legendary unique tone.

the other white meat

Looking at it as a snapshot of specs, it destroys all single channel competitors. The fact that it actually delivers on most if not all of these specs (yes, naturally subjective) is refreshing. It is an actually improved version of a vintage amp, versus a bastardized placeholder. The bullet points you cam here to read: - it's loud as all get out. - it sounds good straight in - it is a great pedal platform even if not 100% pristine clean above 7 on the dial - it is not picky - there is TONS of bass on tap - you can use it as a head for a separate 8ohm cab - verb and trem are foot switchable but the jack is in a weird place - the other tiny 1x10" options I've owned fail to compete (princetons and mesa express 5:25)


The only reason for the half point deduction is that I'm on my 3rd unit. The first one I received from Sweetwater had a speaker problem, so I called Supro up and they shipped me a new one. This one had scratching on the tremolo knobs when you dime the depth. Was I being picky? Yes. But as a paying customer, I want my brand new amp to be perfect. So I sent both the first two units back. Why did I return for another go round? Because this amp sounds absolutely killer. Touch sensitivity, dynamics, pure old school sound, you name it; this amp as well as the other amps in Supro's lineup live up to the hype and the esteemed name of the company. I couldn't have asked for a better grab and go rocking amplifier. I love the cleans on this machine as well; with a delay, it sounds wonderful. Both Sweetwater AND Supro were very helpful throughout this process. Bart Good and Dylan Fisher at Sweetwater took excellent care of me. And Kenny at Supro and even David Koltai the CEO of Supro all helped me along this process. So stoked to be repping this amazing brand, amplifier, and incredible tone. HIGHLY Re

Great practice/small gig amp

I bought this as a practice amp, but have also taken it out on a few gigs. It can compete with a drummer easily, but if the band is loud, you'll run out of clean head room. When the amp breaks up, it's that classic compressed Supro gain. The reverb and tremolo are excellent. No complaints here. I mostly play this with the bass and treble all the way down, and add some EQ in depending on the guitar and room. The bass is pretty much way more than you'll ever need. That is the only reason I give it 4.5 stars instead of 5. I'd love to have the ability to cut some bass, instead you start at zero and can only add more. Strats, Teles, LPs, ES335, ES175, all these guitars sound great with the amp. While certain amps seems to favor certain style overdrives, this amp works with everything I've tried. I also have a blackface Princeton style amp (by Vintage Sound Amps). It's tempting to compare the two, but don't. Different animals. The circuits sound and feel different. I prefer my VSA for gigs because it's a bit more flexible, but the Supro is still an excellent amp.

This amp is phenomenal

It's 4.5 out of 5 because my first amp was a bit of a dud. Sweetwater is serious about their shipping and whatnot so I do not place any blame on them. I put a service request in to Supro, to see if they could figure out what was wrong and they gave me Dave 's cell number to talk to him. They ended up fast tracking me a new amp an hour after we got off the phone. They included a return label in the box for me to ship back for free. He uses a cell phone for all support, but it's him who handles it all. That's fantastic service. Now, the amp itself. I'd never used 6973 tubes before. You are going to see them popping up in all kinds of amps. They are a phenomenal 6L6ish tube that has a dynamic raw sounding gain that comes in just before noon on the amp. It has more mid bight then a 6L6 or 6V6, but I would still classify it as an American sounding tube. It is more open and has higher headroom than a Princeton by quite a bit. I use the flesh of my fingers to pick and do a lot of knob manipulation on a humbucker equipped SG and a SSL-1 equipped Strat. The amp shows no favor. Both presented the dynamic range I desired. The amp is loud enough to play with a band. I would say it's about as loud as a DRRI, perhaps a tad less loud if anything. It is very usable even in the 9 o'clock range, which I found surprising. The tremolo is good. Especially coming after the reverb. It's not as choppy as you'd imagine, the reverb seems to remain audible at all points of the wavelength. It shines in that it avoids muddying your sound and the trem shines through more prominently than if it were before. The reverb is very different from any I've experienced before. It is more behind the note, than in.. Parallel with it. Which it was designed to do, as it states in the book, they wanted your notes to stand out and not be washed out by your reverb. You cannot get an extreme surf wash like a fender at full blast. You can get close enough to where at least for me, the pro's outweigh the con's. (the more you turn it up it does take some bite off the note, like other reverbs, but not as much.) It handles pedals as well as a bogner, Boogie, or fender. If you like to stack gains, say turn your fuzz on on top of an overdrive, it has the headroom to maintain character. The biggest unexpected pro... This thing is dead quite. I'm amazed how quite it is. I, for kicks, turned on my rat clone and bender clone and it was honestly no louder than clean. Even when you kick the reverb all the way up the common reverb noise isn't near as audible as most. I had never owned a 10" speaker and that was a concern of mine I found no real answer to online. I don't think anyone could tell that it's a 10" by listening to it. It doesn't seem to lack in bass, openness, or headroom. These amps are going to get huge.

Great for gigging

I love the size. Sounds great. The reverb is really nice. I wish it had a mid control but perfect otherwise. My new favorite amp for gigs.
