The 50-watt 1x12 combo version of Marshall's JCM900 Hi Gain Dual Reverb, with the same two footswitchable channels, shared 3-band EQ, presence and reverb as the 4100 and 4500. Two EL34s into a Celestion G12T-75 give the JCM900's tighter, more compressed, diode-clipped gain - grittier and more aggressive than a JCM800, and the defining early-90s British rock and grunge rhythm sound.
