Gallien-Krueger MB Fusion 800-Watt Hybrid Bass Amplifier Head

£889.00 £829.00


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 amplifier 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.

This is a great looking amp with some  brilliant features in built such as the thoughtful handle design protects the front panel controls. Internal circuitry indicates problems on the power switch ring. Blue is good!

This is a one off ex show model from GK, full warranty fully boxed as new with footswitch significant saving.
