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

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.

Great plugin, it sounds just like the actual hardware. This will be my go 2 for quite some time.

Punchy and clean

Really cuts through. Lots of definition and very much in your face. Very intuitive to use as well. I demoed it and waited for months for it to go on sale. When it did I nabbed it immediately!

Gallien Krueger Amazing

I have owned an original Gallien Krueger 800RB and have gigged extensively I really know what this sounds like and honestly i reckon this plugin is better.

Nice alternative from Ampeg

Sounds like the real thing. Nice solid bass tone when you don't want or need Ampeg attitude. Pretty versatile in it's own right. Recommended.

Clear, Real, Cuts

Having played with the original unit for years, I have to say I am pretty happy with this plug. Combined with the Eden and the SVT Pro, it fulfills every last bit of bass guitar sound I want to accomplish. It doesn't necessarily sound like the head itself, it has a middle range that I find works well in rock program material with lots of synthesizers. The presets dial in the tight low end these units are known for. I think any bass player would be happy employing this on tracks.

Sell your mother-in-law if you have to!

WOW!! these guys do what they preach. Just get it. You will not be disappointed. Even my wife noticed the difference in bass sound.

Reunited with a tone I used for years.

My first serious bass head was a RB400 then an 800. So getting this tone back in bass recording was exciting to hear again as my old 800 needs to be repaired once I locate in the garage. This is one of my favorite bass amps moreso than ampeg. It’s nice to get that thumpy bright tone with the mid contour down. Throw the empirical lab distressor on it and look out!!!

The base of software changes completely

The base will insist quite strongly that this base amplifier exists.
Sounds like I want to hand over the leading role seat to the base unexpectedly.
Of course, the sound as a side supporting role can be expressed easily and firmly.
It is a plug-in that seems to me that it was really good to buy it.

I own a Kemper and I prefer this

I own a Kemper and have quite a lot of profiles I bought over the year from top vendors. I love how this simulation lets me dial in a great rock bass tone instantly so I keep coming back to this and ditching the Kemper channel after tracking.

Who needs a compressor on bass after that?

Aside guitar, playing bass is a real treat for me. But very frustrating since I can't (neither do my neighbors) afford an SVT in my comfy home studio. Now, forget it. The 800RB is the perfect processor from dull to bright, classic to modern, shy to over-the-top bass sounds. I'm already re-amping old Jazz-Bass tracks to get a far more convincing presence, body, precision and warmth. And it's a breeze to play thru it. Less efforts, more tone!

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.
