Status indicators tell you if there is a shorted output (oc) or over heated (ot) condition. Also, the standby indicator (stby) shows white when the power is off indicating the mains supply is good. If the input is overdriven the clip indicator will flash red.

Legacy combos operate from 100V to 240V, 50/60Hz mains, so you can take them anywhere in the world and simply plug in. No converters or special supplies required.

We have avoided putting a sound effect into the amplifier that may be out of style next year. Instead we use two selected field effect stages configured to optimize the Gate Induced Valve Effect (G.I.V.E.) first pioneered in the 800RB. This can be adjusted to fatten up your sound or to produce heavy overdrive. We have added an edge control to help you shape the sound to your situation.

Legacy combos come with a complete patch bay. The balanced DI has selectable Pre/Post and ground lift switches. Phones and Aux In are 1/8” jacks to accommodate the most common jacks used for these features. Tuner, Footswitch, Send and Return are all ¼” to better accommodate these connections.

All GK amplifiers use a proprietary active, variable Q, serial four band equalizer, the Legacy is no exception. This type of equalization is unique to GK amplifiers and it produces an extremely wide range of usable tone settings. To further enhance the equalizer range, we have added three voicing filters Bump, contour and Presence, activated with toggle switches.

To get the best match between your instrument and the Legacy we have included an adjustable input trim control. When this is adjusted so the clip light only flashes occasionally you have the perfect setup for your instrument.

The Legacy combos use an interconnection system made with gold on gold connectors in concert with multilayer circuit boards instead of wires with crimped on, tin connectors. Gold connectors will never corrode, and the multilayer circuit board provides complete shielding from outside interference.

Legacy combos are cooled using two fans that are temperature controlled. At low temperatures the fans are off, as the amplifier temperature rises the fans come on slowly and run faster the warmer the amplifier gets. Under normal operation the fans may not come on.

Legacy combos use the latest available digital power amps with switch-mode supplies. These deliver a punchy driving sound at a fraction of the weight and power consumption of analogue power systems. They are safe down to two Ohms and operate from 100V to 240V mains.

Legacy combos use light weight plywood construction with ample bracing to make a stiff box. The inside of the cabinet is covered with damping material to absorb high frequencies from the rear of the speaker. This prevents them from coming out the port and interfering with the high frequencies from the front of the speaker. The result is a smooth and pleasing high end response.

A metal grill and ultra-tough cabinet coating finished with metal corners, ensure a long-lasting enclosure that will maintain its good looks over time.

Legacy combos incorporate Neodymium woofers designed and manufactured by GK. Our speakers and cabinets are designed from the ground up to work together to deliver the best possible performance for bass guitar.

Die cast frames are used exclusively delivering greater durability and power handling than the cheaper and more common stamped frame designs.

Our voice coils utilize edge wound aluminum ribbon wire which compared to the more common round wire makes a speaker that is far more efficient with greater power handling.

A compression driver top end solution is far more complex than a simple piezo tweeter. Compression drivers require a real crossover and a system to protect the horn from excessive power bursts. Legacy combos use the same three pole crossover and fast acting protection system found in our Neo Cabinet line.
