800 watts of pure GK power and tone in a five-pound head!

Continuing the evolution of the MB Series, the MB800 bass amp head from Gallien-Kreuger features incredible output, increased functionality, and a completely discreet FET-driven preamp. With 800 massive "GK watts" of power, the MB800 can handle even the largest venues without breaking a sweat, and at 5 lb., neither will your roadie!

All of the MB800's controls are lit to indicate the current operating status, including input clip, tuning mute, Gain A, Gain B/Level-B, power amp clipping, limiter enable, and EQ/Contour settings. The same FET technology used to create the legendary boost (G.I.V.E.) circuit found in all GK amplifiers for over 30 years is used in every stage of the MB800 preamp. Using FET devices to drive the GK four-band active EQ, Contour, and Gain allows the MB800 to transition seamlessly from a full, warm, clean tone to full-on GK growl.
