Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Marshall JCM800 Club and Country 4140 is a two-channel 100-watt combo designed specifically for the UK club circuit and country music market, featuring a clean channel with extended headroom alongside a master volume crunch channel. The Club and Country designation reflected Marshall's recognition that many working musicians needed pristine clean tones for covers and country-influenced music in addition to overdrive capability. With four 10-inch speakers, the 4140 delivers an impressively full and clear sound profile unusual in the Marshall JCM800 range.
