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.

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

Unison Technology for Apollo Interfaces

Harnessing UA’s groundbreaking Unison technology, the Gallien‑Krueger 800RB Bass Amplifier plug‑in gives you the impedance, gain staging, and circuit behaviors that have contributed to making this iconic tone machine one of the most recorded bass amps in history. Just drop the plug-in into the dedicated “UNISON+” insert in UA audio interface Console software.

GK FX Rack

The Gallien‑Krueger 800RB plug-in features tools that greatly add to its versatility when tracking bass guitar. The FX Rack features an onboard noise gate, Power Soak, and EQ filter controls, allowing you to put the finishing touches ‑ before or after mixdown ‑ on your tones. 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.

My Jam

My first real gigging amp was a GK 400RB around 1990. Delivered tone for years. Then onto two GK 800RBs, more great tones! This amp nails the sound.

GK is a beast

I highly recommend this amp sim. However, do not expect to have high end tone right after plug it in. This a realistic simulation and you must tweak it like the real thing until you get the full and pristine tones The GK is loved for. Take your time, learn it and enjoy incredible tones from it. Your ears will be grateful and your low end joyful.

Refined Real Amplifier Sound!

It's perfect for a presence bass sound.
It is also good for re-amping after recording with DI.

Perfect Bass Amp Simulator

Maybe the best. Great tone, nice definition. All the benefits of a real GK without noise or buzz.

OUH LA LA....

As I already own the real double SVT AMPEG, of course I do own the Ampeg Plugs from UAD for more easy use...And until last month, I thought that it was enough for any things...And suddenly, I've decided to buy the UAD Gallien-Krueger bass plug...Just to have something different but.....OUH LALALALALA, an another world of bass suddenly appears! Have you ever tried the fretless sound of this plug? If you do it, then you'll run to your CB card and transform this blue card in a golden dream of bass sounds you've never heard before...

GK800RB

Like the actual amp! I’ve used real Gallien Krueger bass amps for over 30 years. This is exactly right in tone and adjustment. You could not make this better except to add the legendary GK chorus…! Records beautifully. The extra adjustments on FX go further than the original amp! Biamp tweaking finesse is epic too.

Better than my GK 1001RB

I've had a GK1001RB 2x10 combo for years and I love the tones I can get with my Jazz and Precision basses (and my Stingray 5-string, which I sold). This plugin is better than the real thing. An unbelievably good reproduction of the GK tone but zero noise, hiss or hum.

Excellent!

The sound I wanted

Very fast to use, great tone, rich and defined. I was searching for my bass sound but I wasn’t satisfied with the Ampeg simulation; when I tried this one I immediately chose to get it, as this is the best by far… and it sits in the mix perfectly!!

It sounds like an 800RB

We yust reamped a DI and it sounds like the real 800RB.
It would be cool if there is a mic edit like the Marshall amp plugs.

This is it, kick ass bass!!!

If you are looking for this kick ass bass sound look no further, this is a bass amp even Brown Mark from Prince and the Revolution would be proud of!!!

Unique sound

Wanted to ease up creating a good bass sound when recording through DI. This plugin does it for me. Very unique sound: dry, woody and pumping bass amplifier.

Deep bass

It gives “punch” to the naked sound

I had assembled my own fletless bass and tried it out by bypass mode. But no particular feelings came out at all. But things changed after I start using this plug-in. This one changed my sound no matter who says what.

Does what’s on the tin.

Sounds like a GK! If you dig that sound, you’ll want this. Good to have as an alternative to the indispensable Ampeg.

Wonderful amp

Nice sound, suits perfectly for slap, this emulation is much better than the Line 6 POD HD version

Solid. Rich. Defined.

The GK, simply put, gets killer bass tone right from the start. It’s fast, smooth, punch comes to a mix right now and ready. Inspirational!
