Supro 1970RK Keeley Custom Amplifier

Maker: Supro

Model: 1970R Keeley Custom

Condition: Mint, open box



Designed in collaboration with Keeley Electronics, the Supro 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.
