Supro 1648RT Saturn Reverb Combo Guitar Amplifier at a Glance:
  • Vibe up your tone with killer reverb and tremolo effects
  • No off-the-shelf speakers for these vintage-style amps
  • Supro amps: history repeating itself in an awesome way
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 1648RT Saturn Reverb combo guitar amp. When it comes to ambience, the 17"-long, 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 1648RT Saturn Reverb. 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. These special speakers start 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 amps: history repeating itself in an awesome way

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, which began producing guitars and amplifiers under the Supro name. Extremely popular among 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.

Supro 1648RT Saturn Reverb Combo Guitar Amplifier Features:
  • A retro-styled tube guitar amp for modern working players
  • Dual 6973 power tubes deliver 15 watts of pure Supro tone that can be pushed over the edge

No, you can't borrow my Saturn!

Just the best amp I own, especially with the Supro Tremolo pedal adding that wonderful gain at lower volumes. Absolutely great.

Super Supro

I consider myself very lucky, having a collection of amps to choose from. While each has its own strengths and weakness, the Saturn has the most unique character of them all. Its a very quiet amp when its supposed to be, and shouts to the heavens when its called upon to do so. I very much like the tremolo effect, as well its somewhat unique reverb. Overall its a very dynamic amp that seems to give back more than it takes. Strange comment, I suppose I'm a real fan now. I'm compelled to say the first amp I received had an issue. After reporting this to Sweetwater and accepting their sage counsel I found myself taking delivery of a second Supro the very next day. Who else looks after their customers that way? Sweetwater really does provide worry free buying.

Headroom for Pedals

After trying to coax sufficient tone out of my Twin Reverb '65 reissue, I looked for an amp with clean sparkle that I could push without too much volume and one that would take overdrive pedals. After speaking with Matt Emick (thanks, Matt), he directed me toward Supro and I settled on the smaller Saturn. Very pleased with the purchase as it suits my needs well. I like the easy EQ (only a couple of knobs) but I wish there was a mid-range setting.

Supro Saturn Reverb

I really like this amp! Great cleans, great tremolo. You can get just about any tone with this amp! It takes pedals great. I put my Tonebender in front of it and look out! It's a beautiful looking amp, also. My only drawback is the reverb. It's not bad, it's just different. Other than that, great amp! By the way, if you get the footswitch, you need a TRS cable not TR. Many thanks to Jared Kalish, my sales engineer. Great job, as always, Jared!!

Sweetwater Advice

Supro Saturn Reverb

A hefty, four-spring tank delivers gooey-good reverb. The tremolo is equally lovely, if quirky in a signature Supro way. It's relatively restrained - maximum settings throb, but never chop. Also, the response varies according to the volume settings....
