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

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
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™ 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.

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

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.

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!
I use it with my MusicMan and I am completely satisfied. Faithful sound and great ease of work.
L. Segalla
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!!
K. Babic
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.J. Flynn Dale
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!!!
T. van Vliet
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
Great sound and very responsive. Easy to use
K. Ikeda
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.
F. San Filippo
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.
I. Sevruk
Wonderful amp
Nice sound, suits perfectly for slap, this emulation is much better than the Line 6 POD HD version
S. Winkler
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!
J. Manness
The bass amp sim to get
I’m not into the Ampeg sims, but this GK sim sounds incredible and you can use an Ampeg cab IR if you want that flavor. Try this and the Softube Eden amp and see which tone you prefer.
D. Montoya
Everyone is here is right. Best bass tone in seconds.
I wish I'd found this before the UAD ampeg suite I purchased.

Gallien-Krueger 800RB BassAmp
Sounds Great ! Best bass amp so far.
L. St John-Mosse
Sounds just like you want the bass to sound
I found all the Ampeg stuff too woolly and junky - always did for playing live too. This gives me the sound I like from the bass. Does it sound 'a bit 90s'? - Maybe... Prefer that to 'a bit 60s' I guess. No brainer. I was looking to UA for plugins I could 'set and forget' and just get on with tracking. This is the best quality bass sound I've ever got in my home studio and it takes the least effort. Sits in the mix perfectly.
