Supro 1970RKC Blue 810114583869 sku-18530562039 Amp

The Supro 1970RKC Keeley Custom 10 is a Blue 25W tube guitar combo amplifier, listed under All Instrument Amplifier Cabinets as sku-18530562039, UPC 810114583869. Developed with Robert Keeley of Keeley Electronics, it is voiced for use with pedals. Its ECC83S-based preamp has a two-band EQ for stacked overdrives and gain pedals.

A cathode-biased Class A power section uses a matched pair of EHX 6V6GT tubes and produces compression and breakup as the amp is pushed. The tube-driven effects loop is designed for delay, reverb and modulation pedals. A single 10-inch Celestion G10 Creamback speaker provides the sound in the compact 1x10 combo.

At 25 watts, the amp is intended for rehearsal, stage, studio or bedroom use, with a responsive master volume. The lightweight poplar cabinet has Blue Rhino Hide Tolex, white piping, a silver and blue grille cloth, an engraved Supro and Keeley co-branded headplate, and a dog-bone handle. Its sound is described as warm and touch-sensitive, with defined lows, mids and upper frequencies.
