The MB Fusion 800 can handle the largest venues, and you won't even break a sweat carrying it. Also, the MB Fusion 800's controls are illuminated to indicate its operating status.

Extreme functionality

The Gallien-Krueger MB Fusion 800 has an all-tube preamp grafted onto the power amp section of the MB800. The MB Fusion 800 also gives you powerful tone-shaping options, including an active 4-band EQ that's equipped with a contour switch, as well as a footswitchable boost control that lets you kick in extra punch when you need it. Sculpt your tone with the 4-band active EQ and contour controls, and then add just the right amount of growl with GK's gain control.

Highly Portable

At five and a half pounds, the MB Fusion 800 packs in more than 100 watts per pound. And, with that much firepower at your disposal, you'll be ready to push some air in any venue. Plus, it's small and lightweight enough to fit in your gig bag.

All-tube preamp

This all-tube preamp runs on three 12AX7 tubes at high voltage. The MB Fusion 800 has two footswitchable gain and master volume controls. This means that two flavors of all-tube sound are only a tap away. With the wide range of tones and textures available, the MB Fusion 800 is sure to exceed the expectations of any bass player.

MB Fusion 800 Features:
  • Passive and active switch
  • Preamp gain control
  • Contour control
  • Active 4-band EQ
  • Balanced XLR DI output jack
  • State-of-the-art Class D power amp
  • speakON speaker output jacks
Get blown away by the power and portability of the Gallien-Krueger MB Fusion 800!
