ENGLISH From Jim Marshall I would like to personally thank you for selecting one of my new MF350, 350 Watt, MODE FOUR amplifier heads. The very first Marshall amplifier, the JTM45, was built in 1962 as a direct result of my listening to the requests of the guitarists who frequented my music shop at that time. Forty years later, we are still listening to the thoughts and wishes of guitar players from all walks of life.

MODE FOUR Cabinet Options Full Stack versus Half Stack Cabinet Impedance The MODE FOUR can be used either as a full stack (two cabinets) or half stack (one cabinet) configuration.
