Supro 1970RK Details

Designed in collaboration with Keeley Electronics, the Supro 1970RK Keeley Custom is built to integrate your pedals into the heart of an all-tube Supro amplifier.

The preamp and 2-band EQ section are voiced perfectly for running your gain pedals in front of the amp, while still maintaining Supro's signature midrange girth and phenomenal touch dynamics. A transparent effects loop has been worked into the design, providing the ideal point to inject your delay and reverb stompboxes into the amplifier's all-tube signal path. A master volume circuit allows you to control the sound pressure level coming from the speaker, while pouring on copious amounts of gain from the ECC83S-based tube preamp or your favorite dirt pedals.

This 25-watt combo takes Supro's classic rock tones a step further by crafting a design that allows you to get the best out of your stompbox collection. The preamp in the Supro Keeley Custom gives you the headroom needed for the tone from your pedals, while the effects loop allows you to place time-based effects downstream. The amp features a Bruce Zinky designed cathode-biased "Class-A" power section loaded with premium Tung-Sol 6V6GT tubes to achieve an instantly recognizable Supro sound. A custom-made CR10 speaker provides deep bass response with perfectly voiced highs to give you unparalleled performance in a portable, 1 x 10 combo amp.

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
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.
