Jim Kelley Amplifiers

Jim Kelley Amplifiers is the trade name for the guitar amplifiers manufactured by Active Guitar Electronics of Tustin, California between the years of 1978 and 1985. The single channel version of the amplifier employed modest gain preamp stages, Baxandall tone controls, a split load phase inverter, and four 6V6GT output tubes. An improved version was released in 1980 which included reverb and an additional stage of gain. These guitar amps were the first to employ a matched quartet of 6V6GT output tubes. They were also first to come with an optional power attenuator. Further improvements were incorporated into the FACS (foot activated channel switching) model, which built upon the single channel design, and added switchable preamps and tone stacks, and provided relay switching for the power attenuator.
