The MB800 offers what many bassists would consider essentials for a professional–grade amplifier: 800 watts at 4 ohms, along with two distinct gain channels, a 4–band EQ, and contour control. On top of that, there are other goodies including an effects loop, a mute switch, and a –10dB switch for active basses. All of this comes at around 4.9 pounds. This versatile, clean, and loud amp makes it great for backlines and touring rigs alike.
