The Marshall MB15 is a 15 Watt combo bass amp with features that belie its size. 2 channels offer both classic and modern voicing. The Modern channel has a handy compression feature to allow you to practice with awesome, high-volume sound at a level that won't have your neighbors calling the police. The Classic channel sports the tried-and-true volume and gain knobs you know and love. A 3-band EQ allows further tone shaping, a CD-in jack allows you to easily jam with recordings, and a 1/4" line-out jack plugs you right into the PA, a recorder, or external speaker.
