Class H Power Amp

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.

Riding the Rails

Most amps 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.”

Adjustable Limiter

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.

Cabinet Simulation

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.

Studio Headphone Amp

Inspired by some of the industry’s most sought-after studio headphone amplifiers, our 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.

Voicing Filters

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.

Active EQ

All GK amplifiers use a proprietary, active, serial, 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.

Boost

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. We have added an edge control to help you shape the sound to your preference.
