Product Description

Gallien-Krueger Fusion S 1200 1200-watt Ultra Light Bass Head

1200W Ultra-light Bass Head with Class D Power Amp and Tube Preamp, 4-Band Active EQ, and Foot-switchable Tube Overdrive

Ultra-light, Tube-powered Bass Amp Head with Monster Tone

The Gallien-Kreuger Fusion S 1200 is a 1,200-watt compact, ultra-light bass amp head with a Class D power amp and an all-tube preamp with tube-powered overdrive. Vintage-voiced with modern punch and clarity, the Fusion S 1200, can roll with any genre, churning out crisp and articulate clean tones, big-bottom low end, and gritty distortion that'll knock the house down. With its small form factor, ultra-light construction, and robust interconnection system, it's built for the touring bassist. Additionally, a fully stacked feature set, including illuminated knobs, effects loop, and balanced DI, makes the Fusion S 1200 one of the most versatile heads of its size bassists have ever seen.

Vintage-voice with a modern punch

The Fusion S Series pairs GK's signature punchy power section with a characterful tube preamp for a warm, vintage-style sound with modern punch and heft. The preamp is packed with three 12AX7s, with one dedicated to the overdrive channel, for the kind of growling distortion you can only get from overloading a tube. Sculpt your tone to fit any genre with GK's classic 4-band active EQ and push-button voicing filters, including "Bump," "Contour," and "Presence," for on-the-fly adjustments. On stage or in the studio, the Fusion S 1200 is a tonal chameleon perfect for any performance style.

Built to take a beating

Chucked in vans, tossed in trunks, and dragged from show to show, bass amp heads take a lot of abuse, and, over time, the electronics can start to suffer. This means your tone starts to suffer, too, and that is simply not acceptable! The Fusion S 1200 is fortified to handle even the heaviest use. Boasting the same robust interconnection system found in GK's Legacy Series bass amp heads, Fusion S Series heads employ gold connectors on their circuit boards, which deliver a more reliable and purer tone than the standard tin connectors found in other heads.

Jammed with features bassists love

GK loaded up the Fusion S 1200 with a host of features designed with working bassists in mind. Illuminated knobs to adjust your tone on dimly lit stages without squinting into the dark. Mono 1/4" Send/Return for patching in your favorite external effects units. Impedance selector to ensure your 2, 2.7, 4, or 8ohm cabinet receives the optimal load. Balanced DI output with pre- and post EQ for patching into a live-sound board or recording console. And it's all housed in a rugged metal enclosure to withstand those aforementioned vans and trunks!
