Gallien-Krueger has expanded its MB series bass amplifiers with the MB Fusion 800, an 800-watt amp that brings together an all tube preamp and a digital power amp. Similar to the rest of the line, the MB Fusion 800 is built with an aluminum chassis and is sized to fit in a gig bag for easy portability.

The MB Fusion offers many of the same features as the regular MB Fusion, including dual gain stages, a contour filter, and a 4-band EQ. The contour filter and mid-frequency controls are selectable by pushing the knob and setting the frequency you want to adjust. Pushing the Master Knob engages or disengages the built-in limiter, and pushing the Gain A and Gain B knobs allows you to drive the tubes to get different tones in tandem with the Level-B knob. All of the controls are backlit and change colors when engaged including the mute switch to make your settings clearly visible.

Back-mounted features include a selectable headphone/chain/line output, and XLR out with pre/post EQ switch, a footswitch jack and an effects loop.

Yes it is a bit pricey but its totally worth it. GK typically understates their claimed power and this amp is no exception. This amp will eat most if not all 800 watt amps for breakfast, it is loud and powerful. The gain channel (B) is a little less GK sounding, its not as clear as channel A (which sounds like a MB800). This makes the amp more versatile. If you are looking for punchy powerful tone with mucho power this is the amp for you.

I was looking to replace my GK 1001RB with something similar. I had been using a tube preamp with it and loved the tone I was getting. With the MB Fusion I was able to get both a tube pre and a powerful amp in one package.. and it's tiny. The choice of solid state or tube preamp really adds a ton of tonal versatility to this unit. The output power is massive. It's incredibly deceiving that this little unit can push so much air, and not lose any tone while doing it. Very clean output at all levels. I'm very impressed. I run it through Mesa Powerhouse cabs. 2x10 and a 2x12.

I bought this head after having the Fusion 500. I just wanted more power and this thing delivered as expected. It's got that GK tone, but it has more "depth" than the solid states. Light weight, light up controls are the only thing "light" about it. Looks are deceiving, she packs a punch.
