Gallien-Krueger has been at the leading edge of amplifier design and U.S. manufacturing for over 50 years. Building on this long tradition of innovation and state of the art in house manufacturing, GK’s new Legacy Series combos combine tone, power, professional features, and portability within this new offering for the gigging musician.

Legacy Combo 112

At the heart of every Legacy Series combo is the Legacy preamp. Sharing the DNA of the legendary 800RB, the Legacy preamp is the ultimate evolution of one of the most revered bass amplifier preamps ever made. Offering GK’s classic 4 band EQ, foot switchable overdrive with tone control, additional voicing filters (“Bump”, “Contour”, and “Presence”), Balanced DI with Pre and Post EQ, Effects Loop, Aux in and Headphone output connections, the Legacy has the features for the modern player and the tone that has set GK apart for decades.


Legacy Combo 210

The Legacy Combos are available in 1×12, 1×15, 2×10, 2×12, and 4×10 speaker configurations and come equipped with Neodymium speakers designed and manufactured in GK’s California factory. This enables players to select the performance and portability they require.

All Legacy combos are equipped with the latest 800 watt switch mode power amp available to provide the horsepower required to cover large stages and outdoor venues, plus universal power for seamless 100 to 240 volt operation. This makes the Legacy Series combos well suited for everything from local jams to major tours and everything in between

Introducing Fusion S Series

The Fusion S Series Heads are GK’s brand new Class D Model heads with a tube preamp. 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. These high powered heads incorporate 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 and but adding a beautiful stage presence as well. Each illuminated knob is also push activated, with additional voicing filters and tonal characteristics built in.


Fusion S 500

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 that 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. 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 8ohm cabinet configurations.

US Manufacturing

In the last three years GK has made significant investments to bring as much of the manufacturing process as possible to their US factory in Stockton, California. They have invested in an automated PCB assembly line enabling them to bring all their circuit board assembly in house, providing improved quality control and reliability. Their new product’s chassis are 100% aluminium 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.   GK design and build all their own speakers to match their cabinets achieving exceptional performance and reliability at a reasonable cost.


New Technology

GK state, “We have 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”.
