The Fusion 800S Ultra Bass head is part of Gallien-Krueger’s brand-new Fusion S Series of Class-D model heads with tube preamps. The rich warmth of tubes, combined with the quick, punchy power section that GK bass amps are known for, is an experience like no other. This high-powered 800W head incorporates three 12ax7 tubes in the preamp, including one dedicated to the overdrive channel, making it GK’s first-ever tube-driven overdrive channel. Illuminated knobs add an extra level of sophistication and design by not only making it easier to dial in your tone on stage, but adding a beautiful stage presence as well. Each illuminated knob is also push-activated, with additional voicing filters and tonal characteristics built in.
Like the Legacy Series, the Fusion S series uses a unique interconnection system that eliminates problems that can develop over time from constant vibration and temperature extremes gear is subjected to with heavy use. Using circuit boards with gold-plated connectors, rather than cables with standard tin connectors, this type of construction delivers a more pure, reliable sound. The Fusion 800S' features include GK's classic 4-band tube-driven EQ, tube Overdrive, complete with tone shaping, additional push-button voicing filters, such as Bump, Contour and Presence, Balanced DI with Pre and Post EQ, an Effects Loop, AUX and headphone connections, and Load capacity selection, to deliver optimum power into 2-, 2.7-, 4- and 8-ohm cabinet configurations.
U.S. Manufacturing
In the last three years, GK has made significant investments to bring as much of the manufacturing process as possible to their U.S. factory in Stockton, California. They have invested in an automated PCB assembly line enabling them to bring all their circuitboard assembly in-house, providing improved quality control and reliability. Their new product’s chassis are 100% aluminum-finished with very tough black anodize. All the graphics are laser-etched into the surface during assembly so they will never fade or wear off. Gallien-Krueger designs and builds all their own speakers to match their cabinets achieving exceptional performance and reliability at a reasonable cost. They are working hard, and doing whatever they can to keep manufacturing and jobs in the United States.
New Technology
Gallien-Krueger has made a major improvement in the manufacturing process by replacing standard interconnecting cables and tin contacts with multilayer circuit boards and gold connectors. Multilayer circuit boards provide built-in shielding for sensitive circuits and provide a more pure signal path for your music. Over time, standard cables with crimped-on tin connectors tend to exhibit failure issues due to various corrosion conditions and are subject to sound pollution and unwanted interference. Over time, tin contacts will degrade and gradually affect your sound, while gold connectors do not, keeping your excellent sound year after year. There are many innovations included in the Legacy Series that work together to give you a sound like you have never heard and this attention to detail, technology and manufacturing insures your new Legacy will allow you to express your creations for years to come.
