Microbass and MB Series combos set the standard for performance and portability that continues to influence the industry to this day. Building on this long tradition of innovation, the Fusion Series Combos utilize GK’s unique 6 stage tube preamp, 800-watt switch and Neodymium speakers to provide tube tone and high performance in a compact combo format that tube aficionados have previously only found in separate head and cab rigs.

Fusion Combos feature a unique interconnection system utilizing circuit boards with gold plated connectors rather than cables with standard tin connectors to eliminate problems related to constant vibration and temperature extremes that can develop over time. The Fusion Combos are available in 1x12, 1x15, 2x10, 2x12, and 4x10 speaker configurations and come equipped with Neodymium speakers designed and manufactured in GK's California factory and high capacity 1” tweeter. 

This enables players to select the precise form factor best suited for their day to day needs as they travel between rehearsals and recording sessions while the 800-watt switch mode power amp provides the horsepower required to cover large stages and outdoor venues. In addition, universal power for seamless 100 to 240-volt operation makes the Fusion Series Combos well suited for everything from local jams to major tours anywhere in the world.
