Gallien-Krueger 1001 RB Legacy Bass Amplifier Head (600 Watts)

The goal was to create a standard in bass amplification. After five years of design work, 20 revisions, and thousands of hours in the lab, they created an unrivaled analog bass amplifier. Unprecedented performance, studio quality sound, boundless features, punch that never quits, indestructible analog power, and a metal enclosure machined to perfection. The 1001RB and 2001 RB Legacy achieves everything set out to do and more. This is the standard of excellence for the modern professional bass player.

Designed by founder and president, Bob Gallien, the RB Legacy is the result of more than 50 years of knowledge and dedication to his craft. His unrelenting drive for innovation and refinement has not only left a lasting influence in the world of modern bass amplification, but also raised the bar for what a bass amplifier can do. The RB Legacy sets the stage for a new era in professional sound equipment and aims to meet the needs of the most discerning of players, whether that's on the road, in the studio, or at home.

The RB Legacy 1001 and 2001 are equipped with Class H power amplifiers, which have two power supplies. One that operates lower output levels and one that handles higher output levels. These amps are designed to be played loud and with this configuration, it not only improves reliability, but allows you to play hard into the rails (maximum output) without overheating the amplifier or worrying about your tone giving out, a problem with many bass amplifiers.

Most amps… read more start to run out of juice as they reach their maximum output, but the RB Legacy delivers almost twice the current required to develop full power. So, you can keep control over the speaker cone, even in extreme conditions. Without this extra capacity, you get an unresponsive sound, lacking punch or definition. When you play really loud -- or "into the rails" -- the RB Legacy produces a powerful, growly sound. Otherwise known as "riding the rails."

Another new feature of the RB Legacy series is an adjustable limiter. This can be used to "limit" at the rail (maximum output) and can be adjusted to pull the signal off the rail, keeping the output clean. This helps tame excessive signal peaks, reduce unwanted transients and prevent unwanted distortion.

Turn on the cabinet simulation to get a faithful representation of a live cabinet feel that can be used with your DI and headphone signal. This gives you more control over your DI tone whether you're recording, playing live, or practicing at home.

Inspired by some of the industry's most sought-after studio headphone amplifiers, class A headphone amp delivers studio quality power into any headphones from 8 to 300 ohms. Whether at home or on stage, you'll have your tone on tap.

The RB Legacy includes three filters that completely re-voice the amplifier, maintaining a neutral volume, so you don't have to adjust the volume controls after turning them on or off. Bump adds a round bloom... contour boosts the highs and lows while dropping the mids... and presence adds a sheen to the top end.

All GK amplifiers use a proprietary, active variable Q four band equalizer. The controls are in series, so they won't add or cancel frequencies that compromise your sound. As you adjust, the active equalizer reshapes based on the cut or boost you are adding. This produces an extremely wide range of usable tone settings.

The RB Legacy uses two selected field effect stages configured to optimize the Gate Induced Valve Effect (G.I.V.E.), or tubey grit, first pioneered in the 800 RB. This can be adjusted to fatten up your sound or to produce heavy overdrive. GK have added an edge control to help you shape the sound to your preference.
