The pre-amp and 2-band EQ sections will handle your gain pedals in front of the amp, while still maintaining Supro's signature midrange girth and touch dynamics. Or use the front panel send/return effects loop to inject delay and reverb stomp boxes directly into the amplifier's all-tube signal chain. A master volume circuit allows you to control speaker loudness but maintain the huge gain from the 12AX7 tube preamp.

The Supro Keeley amp features a Bruce Zinky-designed cathode-biased Class-A power amp section loaded with two, premium Tung-Sol 6V6GT tubes to achieve the instantly recognizable Supro sound. The open-back Supro 1970RK amp has a custom-made, 10-inch CR10 speaker with good bass response and smooth high end.

The Supro Keeley amplifier is hand-assembled and tested by musicians in Port Jefferson, NY, USA, measures 19 7/32 X 9 7/16 x 14-inches, and sells for $879 MSRP.
