What is the Axe FX II XL? 

The Axe-Fx II XL is an advanced digital preamp and multi-effects processor for guitar, bass, and other instruments. 
It is As the flagship product from Fractal Audio Systems, it delivers the world’s most advanced amp modeling, plus 
our best-ever effects technology with state-of-the-art algorithms of outstanding quality. It replaces amps, 
speakers, effects, studio equipment, and more, with an all-in-one, end-to-end 

total tone solution

 in a single black 

box. It is the latest hardware revision Axe-Fx II, following the Axe-Fx II Mark II, adding more preset/cab memory 
and a FASLINK™ port. 

Inside, a vast virtual environment allows you to build your dream rig (hundreds of them in fact). Choose from an 
inventory with the best of vintage treasures and modern masterpieces. Arrange components any way you like, 
limited only by your imagination and the unit’s “CPU” power. Dial in your sound using basic controls, go deeper 
with optional advanced parameters, then save presets for instant recall when playing or performing. The sound is 
of uncompromising quality, due both to extremely high standards of hardware design and advanced proprietary 
software. 

The Axe-Fx II creates great tone by paying great respect to its heritage. We’ve performed thousands of hours of 
analysis of the best amps, cabs, and effects of all time, painstakingly replicating the sound and feel of the originals. 
But while emulations are impressive, the Axe-Fx II goes well beyond mere “models” to become a do-it-yourself 
platform, where musical creativity is free to go beyond traditional limits with unrivaled flexibility. You don’t need 
to be an engineer, either; the unit is very user-friendly, especially when connected to Axe-Edit, our free companion 
software product. Musicians tell us that the Axe-Fx II is inspiring and fun. Here are some highlights: 

Freely Routable:

 Place effects freely in any order and layout—series, parallel, or complex networks, including 

feedback loops, plus external send and return at any point in the signal chain.  

Totally Programmable: 

Every effect has a full complement of parameters offering desired features and 

tremendous range. Gone are the limits of processors with restrictive options or insufficient depth. 

Extensively Controllable:

 The “MODIFIER” system provides great real-time control options. You can use pedals, 

switches, MIDI, or internal “Controllers” to remote control or automate parameters with extreme flexibility. 

Of the Utmost Quality

: Sound quality is first-and-foremost in the hardware design, and in every detail of our 

proprietary natural processing software algorithms. Many of these replicate patterns that occur in nature (thus 

Fractal”

 Audio Systems.) The amp models use multiple unique, dynamic, non-linearity generators that produce 

smooth, even-ordered harmonics, giving dynamics and dimensionality that other processors lack. Our effects have 
been vetted and championed by some of the world’s most demanding and discriminating players.  

Able to Replace Entire Rigs: 

The complete integration of all components into a single system offers many distinct 

advantages, among them great consistency, simplicity, and control. And of course, after you’ve replaced a rig, the 
Axe-Fx II lets you continually re-invent it without ever touching Velcro, rack screws, or your credit card.  

All said, given everything the Axe-Fx is, it is really about 

you

, and everything it 

becomes 

in your hands.
