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

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.

Key Features

Legendary tone of the Gallien-Krueger 800RB bass amp heard on countless recordings, officially licensed and authenticated by Gallien-Krueger

Gallien-Krueger's unbeatable Voicing Filters — Low Cut, Mid Contour, and High Boost — for instant shaping of overall bass tone

Four active EQ bands for precise tonal shaping

Full range or bi-amplification with adjustable crossover, allowing high and low frequencies to be amplified separately

Two dedicated Recording Chains for each power amp, each containing 64 Recording Chains with multiple speaker cabinets

Unison™ technology for Apollo interfaces, for the tone, touch, and feel of the original Gallien-Krueger 800RB

Another great emulation from UA

Basses sound punchy and have great definition, just like the hardware GK amps.

Very pleasing

I was not familiar with playing GK amps, but heard that they had punch, and had solid articulation up the neck. I just finished a project where the instrument was a Bass VI, and this plugin sounded great and mixed really well.

Identical

If you liked this amp you’ll surely love the Unison emulation. .

Fair tracking

I have the Plugin Alliance one, but needed this for tracking. Incredible sound

The resemblance is to the original GK is uncanny

The backbone of so many backlines. I've used GK Riggs live for years and this plugin truly captures the GK tone brilliantly. Another another one knocked out of the park by UA

A true representation of a classic bass head

The sound that powered the low end of so many back lines. UA knocked it out of the park with this one and nailed every nuance of how this Amp was meant to sound

First Bass Rig ( guitarist that normally uses Synth bass )

i needed something to do with my SPL Vitalizer, ( it sits in it's folder unused for the most part ), so i am piecing together a tracking Bass Rig with the GK 800RB into the Fairchild 660, into the SPL ( using the SPLs compressor to catch the spill over from the 660 High Pass ).. if it's part of my tracking channel, i will make it work; because it will be part of the tweak that goes down.

Get Bass Sound that saves time.

I owen a Gallien-Kruger 1001RB and now I don't have to D.I. out and mic up the cabinets to get a great sound that sits well in the track. Now I just plug in the bass to my Apollo and and add this unison plug in and I'm done.

Plugin inoperative

Only plugin I have that’s not compatible with latest console SW. I guess I’m out $80. Not very happy about it

Look no further!

Recording bass DI is kind of the standard, i typically use a SansAmp Tech21 or one of my Octo-Pre's to dial in a tone; so i tried that in Luna first. As i was new to Luna, and using my Apollo X8p. Sounded great! Tried the different Ampeg Plug-ins bc i saw them used in the tutorials- not so impressed- after some tinkering theu were fine but i would probably just not use a plug-in and dial in the desired tone as per my usual methods over that. Then i tried the Dave Eden amps- still felt flat and lifeless to me. Then i tried (as a one last "i will probably hate this too but i may as well try it" type thing) and HOLY S*@$%!!! I immediately paid for the full version! No need to finish my 14 day trial! Hahahaha
This is all you will ever need for a bass amp Plug-in!

Best in Studio

I'm using it at home recording and rehearsal. Best for both worlds.

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.
