The Gallien-Krueger 800RB is widely regarded as one of the most influential bass amplifiers ever made. From countless stages to world-class recording studios, its unmistakable punch, lightning-fast response, and articulate tone helped define the sound of modern bass for decades.

At the heart of the 800RB is GK's legendary Bi-Amp design, delivering 300 watts to the low-frequency section and 100 watts to the high-frequency section. Combined with the variable crossover control, you can independently shape the balance between deep, powerful lows and crisp, articulate highs for a remarkably tight and responsive sound.

The 800RB has a character all its own—quick, punchy, and incredibly dynamic. It sits effortlessly in a mix while remaining responsive to every nuance of your playing. Whether you're after warm vintage growl, tight slap tones, or aggressive rock punch, this amp has earned its reputation as one of the all-time great bass heads.
