The Marshall MB30 is the 30Watt 1x10 bass amp. The MB30 takes the budding bass player a step further to hitting the stage with aggression and growl. Like the 15 Watt combo, the MB30 has two channels (Modern and Classic) with a shared 3-band passive tone network, featuring a mid Voice control with three modes. The Modern channel has a switchable compressor with variable level control. Both channels are selectable by the optional single footswitch.
