The MA series was designed with the flexible control demanded by today's players in mind but with a streamlined feature set to keep it cost effective.

Whether in your own home or gigging, setting up the sounds and relative levels is very easy; Starting at the Overdrive Channel with the Boost enabled. This mode can deliver the highest gain and offers some real mean Marshall signature grind for effortless soloing or powerful metal riffing. Set all EQ controls and Crunch Balance to 12 o'clock for now. Turn up the Volume and Gain to get your sound at the required level when playing solos. Fine tune that sound with the EQ including the Presence and Resonance controls.

When you are happy with your 'solo' mode then disengage the boost to give you your rhythm or crunch sound. The volume and gain of this mode is further controlled by the 'Crunch Balance', (this control does not affect the Boosted mode). The Crunch Balance enables a player to preset the gain/volume difference between their rhythm and solo modes and the key to success is the careful balancing of the Overdrive Volume, Gain and Crunch Balance controls.

Finally, the Clean Channel with its own dedicated EQ section can be set to match up with the Overdrive channel.
