The 250ML is Gallien-Krueger's lunchbox-sized solid-state stereo guitar amp, launched in 1983, with two small power amps driving a pair of 6.5-inch speakers. Channel A is clean, with its own volume and preset compander and gain switches; Channel B is a solid-state overdrive with its own volume and gain switch. Both share an active four-band EQ, then a stereo IC echo and chorus, an effects loop, and headphone and direct outputs.
