Blue Cat's Axiom
"The next generation: your axe beyond the limits"


Blue Cat's Axiom - Guitar & Bass Amp Simulation With Effects (VST, AU, AAX, VST3, Standalone)

Blue Cat's Axiom is a powerful and open multi effects processor and amp simulation software for guitar and bass. Based on the acclaimed Destructor plug-in for amp simulations, Axiom offers an infinite number of exceptional tones for your axe.

It includes two amp simulations channels (with pre and post effects) that can be mixed together or used alternatively like a real amp. You can choose your amp models from hundreds of presets or launch the amp editor to build your own, with complete control over the tone. Additional input and master sections let you adjust the tone at the input and the output of Axiom, with 4 additional effect slots each and an integrated high precision tuner. A brickwall limiter also protects the output from overshoot.

Axiom includes 40 built-in effects that can be loaded in any of the 32 plug-in slots, including a built-in version of Late Replies for creative delays and reverbs, and a built-in version of Destructor to add your own distortion pedals, cabinets or additional amp simulations.

Blue Cat's Axiom is not limited to its built-in effects: these slots can also host third party Audio Unit, VST or VST3 plug-ins: you can use your favorite plug-ins anywhere in the signal chain and expand Axiom's capabilities.

And because playing alone is not so much fun, we have added a tools section with 3 additional slots to load virtual instruments: add a metronome, a drum machine, sequencer or your keyboardist's favorite synthesizer there to get it mixed with your guitar.

If you are looking for amp simulation software without the effects, see the Destructor plug-in. For a plug-in host & multi-effects processor without amp simulation, check out Blue Cat's PatchWork.

Credits: this plug-in includes several factory presets created by Hans Van Even.

User Comments & Reviews

"Overall I think this is a must have plugin for anyone. Guitarists and non-Guitarists alike. For guitarists/bassists that enjoy experimenting, there’s nothing comparable that’s targeted to you." - Robert Randolph [Read Full Review].

"I have never had this goosebump feeling as it just happens when playing with AXIOM [...] The virtual Superamp Axiom by Blue Cat Audio is definitely worth a tip!" - [Read Full Review].

"I have been playing with Axiom for one day NONSTOP. It is wonderful. It is probably one of the most well thought out plugins I have ever used. [...] The sounds are incredible and very full. [...] All in all a great product and I am very happy with it so far." - Dallon Ghan.

"Avec Axiom, Blue Cat Audio nous impressionne. [...] C’est un logiciel jouissif de par son principe, et des sonorités convaincantes respectant la dynamique des instruments." - - "Innovation Award" [Test Complet].

"I'm really getting into this plugin! I haven't really appreciated the possibility to leave the final guitar sound sculpting decisions until the final mix before, but with the Axiom this is obvious to me. Apart from the fact that it sounds great, is very easy to understand and edit and is very inspiring. It also has good presets that I use as starting points for my own sonic adventures. In short, very inspirational." - Mats N on The Gear Page - [full review and song].

"I can't imagine how much work and effort goes into developing a user friendly GUI for a plugin with the amount of incredible features provided here.[...] There is simply no tone you can't build in Axiom.[...] Axiom and Destructor give you a million high value ways to create your own professional quality guitar tones." - Honest Amp Sim Reviews - [Read full review].

"Dans un marché plus que concurrentiel, Blue Cat Audio arrive encore à innover avec cet Axiom, plein de sons pour guitares et basses, entre autres. En combinant un processeur multi-effet et des simulations d’ampli sous la même interface, Axiom pourrait bien devenir l’arme fatale des guitaristes en home-studio et, pourquoi pas, sur scène !." - KR Home Studio - Juin 2018.

"I think it is one of the best values out there. You can do so much with this plug-in.[...] I definitely put this one in the recommended pile." - [Full Video Review].

"I own several leading brands of software guitar emulation but Axiom is the first one I have used where the presets actually sound like well recorded real amps and are not instantly given away by the "digital fizz" which marks them as emulations and makes them not sit well in the mix. My initial experience is overwhelmingly positive, a quick tweak of an existing preset on the easy to use HMI and you have an eminently usable sound that sits in the track. In my view Axiom is a significant improvement in the state of the art of guitar amp emulation." - Robert Miller.

"An extremely powerful multi-effects that rewards not only on electric guitars and basses, but also on many other instruments as well as vocals or synthesizer and keyboard sounds" - Beat Magazine.
