Just when you thought GK couldn't take the MB Fusion line any bigger, out comes the Fusion 800, a massive all-tube preamp high powered by 800 watts.

Imagine being on a dark stage, the controls of your illuminated amp head easily visible.  What would you do with the 4 band EQ? The Effects Loop?  The lights go on and the show starts.  Would you stomp your way through the act with foot switchable channels or set it one way for the night?

Now imagine it's the end of the night and you have to load up your equipment.  Who wouldn't want to move a 5 lbs amp head compared to other options?
