Amplify Your Pedal-crafted Tones with Class

Designed in collaboration with Keeley Electronics, the Supro 1970RK Keeley tube combo amplifier sets an amazing sonic foundation for your guitar tone. And with input from the pedal masters at Keeley, it's the perfect platform for your pedalboard. It's got everything guitarists have come to love about Supro amps — high input headroom for dynamic tone, signature midrange girth that's always appropriate, and a touch-sensitive, harmonically rich response. Its 6V6, Class A power section drives 25 watts into a custom CR10 speaker, delivering a wide and balanced sound that does justice to complex, pedal-crafted tones. Complete with a transparent effects loop, and a master volume control for accommodating any room, the Supro 1970RK Keeley combo is an extremely versatile tube amplifier.

Tailor-made for your pedalboard

Why do certain effects pedals sound better with some amps than they do with others? There are a lot of factors, and Supro and Keeley took them all into account with the 1970RK Keeley combo. It has very high input headroom, which means your boost and drive pedals won't produce unwanted muddy preamp distortion. You can drive the preamp tubes if you want, though — just crank the input volume and roll the master volume back to taste. A solid-state rectifier bolsters the headroom while giving you faster transients and more output power than a tube rectifier can traditionally provide. Also to the benefit of your pedalboard, the custom speaker is voiced for balanced tone that accurately reflects your tone choices, while also sounding incredibly vibrant.

Custom speaker delivers punch, girth, and sparkle

Ask any guitarist at Sweetwater — the speaker in your combo or cabinet plays a huge role in your tone. The amp wizards at Supro know it too, and that's why they loaded the 1970RK Keeley combo with a custom-designed CR10 speaker. It's voiced for deep yet tight bass response, Supro's signature midrange girth, and sparkle that never becomes icy. The cabinet is deeper that a vintage Supro 1x10" cab, adding to the powerful low end. Even with the rest of the band rocking, you can feel the 1970RK Keeley right in your gut.

Transparent effects loop for routing flexibility

With their high input headroom, most Supro amps are just fine with your effects being run into the front end. To make the 1970RK Keeley combo as flexible as possible, this Supro packs a transparent effects loop for your time-based effects like delay and reverb. It's also a great place for a boost or EQ pedal, bolstering your post-preamp tone before it hits those glorious 6V6 power tubes.

Supro 1970RK Keeley Tube Combo Amplifier Features:

  • All-tube, 25-watt, 1 x 10" combo amplifier
  • Designed with Keeley Electronics to be an awesome amp for pedals
  • High input headroom and balanced, wide-ranging speaker do justice to your pedal-crafted tones
  • Master volume control allows you to drive the input stage while controlling overall volume
  • Transparent effects loop for delays, reverbs, EQs, and boost pedals
  • Custom-designed CR10 speaker delivers punchy lows, girthy mids, and velvety highs

Does What It’s Designed to Do and More

There is already good info out there about this amp and I decided to give it a shot based on that research. I wanted it all. Great tone, effects loop, plenty of clean headroom, lightweight and a small footprint. I remember the first night I used it at a show. It was New Year's Day. Two well known musical individuals in my area specifically came over during a break to compliment my tone. For me, this amp is a winner.

Magnifico

For all the Amplifier that I used this is the most clear and the versatile. It suits to all the Pedals that I have. Even if it's too small it dan deliver a super nice sound that you want to hear.
Rated 5/5

It's a keeper!

I'll say this up front, I'm a Keeley pedal junkie! Now with that said, This 25 watter does boast some niiiice headroom. Your drive pedals subtle nuances come out. The Efx loop has your delay/reverbs dancing, but I've tweaked some of my mod pedals to work best in the front. My Keeley Delay WS and Dyna-Trem, sound hugh in the loop, but my 30ms ADT, and Dyno-My-Roto sound thin, and distant.
The amp overdrives naturally well. Cranking it with the Compressor Plus in front makes me drool (Y'all) know what I'm talking bout. The treble pot sweep keeps it subdued, allowing you to roll in treble easy. The cab is solid, allowing the amp to resonate very, very well. I have no desire to swap out this CR 10 proprietary Eminence speaker. It's articulate, and responses to the killer amount of bass in this thing. It's a simple format. I like do'in more with the less features.
Music background: Open Mic Man, part time gigger, Keeley pedal junkie.

Great transparent and versatile combo!

I have not owned a tube amp for almost 10 years and honestly, didn't think I'd ever get another one. Years ago, I started collecting a few Keeley pedals as I have been friends with Robert since high school and watched him move from modifying pedals to making his own outstanding creations. About two years ago we met up at the Sweetwater Gearfest and told him I was planning on buying a small tube combo to run my pedals thru. Never could I have imagined that he would do a collaboration with Supro and would be exactly what I was looking for!

This amp is simple but has so many great features. It is super light, small, and easy to carry but is definitely a loud 25 watts. It is a perfect pedal platform with just a few controls and lets the tone come from the pedals. The amp has a great crunch by itself yet is really clean with the master volume up and standard volume control down low. Sounds great at low volume too.

If you are looking for a well priced tube combo that can handle the tones and is extremely versatile, look no further. What can I say, my buddy makes great gear!!
Rated 5/5

Perfect

Was deciding between this and 68 custom deluxe. This is a much more versatile amp. I've tried the 68, which sounds wonderful, but actually is too distinct sounding to be a versatile amp. The Supro is more transparent and can do just about anything you ask it with the right pedals.

Very well packed from Sweetwater and excellent service from my sales associate.
