A legendary, rock star-approved bass amp, exclusively for UAD and Apollo.

The Gallien-Krueger 800RB is the legendary solid-state bass amp used on countless hit records by artists like Red Hot Chili Peppers, Radiohead, No Doubt, Guns n’ Roses, and more. When it was released in 1982, the 800RB dazzled with its bi-amplified operation and DI output, quickly becoming an industry standard for countless bassists, touring bands, and backline companies.

Developed by Brainworx, and officially licensed by Gallien-Krueger, the Gallien-Krueger 800RB Bass Amp plug-in provides an exacting emulation of the original amp — along with indispensable modern features.

Now You Can:

Record your bass through a spot-on emulation of one of the all-time classic bass amps

Run two Recording Chains and independently select dual cabinet/microphone combos

Shape your tone with Gallien-Krueger’s unbeatable voicing filters and 4-band EQ

Track with authentic bass‑amp feel through an Apollo interface using Unison technology

The Industry Standard

The Industry Standard

Like the original hardware, the Gallien‑Krueger 800RB Bass Amp plug‑in is a Swiss Army Knife of bass tone. GK's patented voicing filters offer instant access to classic EQ profiles in the low, mid, and high frequencies, and its 4‑band active EQ lets you dial in your ideal tone with precision and ease no matter what type of bass you play.

Two is Better Than One

Two is Better Than One

The Gallien‑Krueger 800RB plug‑in emulates the original hardware’s bi‑amplified architecture, providing two different power amps ‑ one for the lows and one for the highs. An adjustable crossover allows you to control which frequencies go to which power amp, and each has a master volume knob, making it easy to dial in just the right amount of bass or bite.

Unison<sup>™</sup> Technology for Apollo Interfaces

But it’s the 800RB plug‑in’s 64 Recording Chain presets that give you the ultimate in flexibility. These presets give you endless combinations of vintage mics, cabinets, and outboard gear ‑ like having an engineer patching you through various chains.

Am I Really Hearing This?

Any tone, easy to dial in, simply an outstanding sound. I mean just like i have the amp here in the room with me. There is no other plugin that even comes close to sounding this good. Hats off UAD.

Killer Bass Amp!

I played and toured with several bass players who used Gallien-Krueger amps. I'm blown away by this plugin. I'm finding it really easy to quickly dial in the desired tone I'm looking for.

Очень правильное звучание

Играл на много на «железных» приборах. Этот звучит даже лучше-сочнее и собраннее. Можно накрутить хороший звук. От игры получаешь удовольствие и записывать станови ся проще.
