The Axe-Fx and Axe-Fx Ultra from Fractal Audio Systems are a breakthrough in guitar effects processing. Advanced processing and unprecedented computing power offer not only the sound, but the FEEL of a real tube amp. Our proprietary algorithms accurately simulate the varying frequency response of an overdriven tube amplifier. Unlike conventional tube modelers where the frequency response is static, the Axe-Fx gives the guitarist a true dynamic experience. Cranked-amp tone and feel at any volume!

A 500 MHz, dual-core processor equips the Axe-Fx with more raw compute power than many desktop computers. Able to process 2 Billion floating-point instructions per second, nothing even comes close to the power of the Axe-Fx. Enough power to run 10 super-high quality effects simultaneously (typically 12 or more depending upon effect resource requirements).

In addition to the best amp/cabinet simulation the Axe-Fx provides the finest reverb, chorus, flanger, phaser, etc. etc. The unprecedent procssing power of the Axe-Fx allows studio quality procssing in a portable, rack-mountable chassis. No cheesy stuff here, just clean, clear, pristine effects.

Uncompromising amp simulations and painstaking attention to detail give a warmth and body that no other processor can match. Full and round with no digital "fizz".

Graphic Liquid Crystal Display (LCD) unit makes routing and editing easy and intuitive. No cryptic menus, or single line alphanumeric displays to contend with. Real-time monitoring of controlled parameters is also provided.

Up to 16 parameters can be controlled in real-time via any combination of external or internal controllers: eight external controllers , two LFO's, two ADSR generators, envelope follower, pitch follower, eight-stage sequence generator. Unique modifier function allows mapping of control values to parameter with many different curves.

Top-of-the-line, 24-bit Cirrus Logic® converters assure signal purity. Our proprietary analog front end features no electrolytic capacitors in the signal path, only high-quality film types. The output signal path likewise has no electrolytic capacitors. High-performance Analog Devices® op-amps are used in all signal paths. All this adds up to an extremely low noise floor (better than -105 dB).

While other companies are outsourcing their production to Asian manufacturers, we believe that keeping production domestic insures a higher quality product. We also believe it benefits our nation and its economy in the long-run.
