Marshall Club & Country 4140 - Channel 2 preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Club & Country 4140 is a 100-watt two-channel 2x12 reverb combo from the late 1970s, carried into the JCM800 series and voiced for clean headroom for country and club players. Each channel has its own pair of inputs, Volume and Treble, Middle and Bass, the first with a footswitchable boost; they share spring reverb and a Master Volume. An ECC83 inverter drives four EL34s (6550s on US models).
