Made at their UK factory and loaded with Celestion speakers, Marshall's engineers have worked hard to ensure that the MC series cabs are the most affordable full size Marshall cabinets available, while still providing the sonics and build quality that are more than worthy of the badge they wear. The MC412's 200 Watts of power, combined with the same flexible Mono/Stereo switching of our 1960’s, means it will handle any Marshall guitar head with ease. Marshall recommends using 4 Ohms for getting full power out of the MG and AVT heads, while the 16 Ohms setting is preferable for use with their valve heads.
