Fractal Audio Systems AX8

AX8 Amp Modeler/Multi-FX Processor


The new AX8 is an all-in-one Amp Modeler + Multi-Effects Pedalboard Processor. It features many of the same leading-edge technologies utilized in our flagship Axe-Fx II processor, now offered in a floor unit at a fantastic price. Quantum Amp Modeling gives the AX8 over 222 exquisitely modeled amps that recreate the incredible nuanced tone and feel of real tube amps: sparkling cleans, elusive “edge of breakup” tones, and everything from warm, touch-sensitive overdrive to face-melting distortion. Ultra-Res™ Speaker Simulations offer a range of cab tones, with 130+ “Factory” cabs, plus 512 “User Cab” memory slots to store entries from our celebrated Cab Packs. Add to this a stunning selection of effects utilizing our state-of-the-art algorithms: G3™ drive pedals, HD reverbs, compressors, delays, EQs, choruses, phasers, flangers, rotary, tremolos, pitch shifting, wah, and many more. Above all, the AX8 sounds great, with a pristine, high-quality signal path and the signal processing power that makes Fractal Audio Systems the industry standard for today’s most discriminating professional guitarists.

Easy-to-Use Front Panel Amp Controls

Hands-on editing has never been easier than on the AX8. Dedicated LED-ring knobs give direct access to eight “must-have” amp controls: Drive, Bass, Mid, Treble, Presence, Depth, Master, and Level. Add to this five additional “soft knobs” beneath a brilliant LCD display, six buttons, including SHIFT for extra functions, front-panel LED meters/indicators, 27 LEDs in three colors, and dedicated knobs for output levels.

Superb Speaker Simulation

The AX8 features a high resolution speaker simulator with 150+ “Factory” models and room for 512 “User” cab locations. The Cab Block is the key to “direct” tone — able to reproduce the sound of a cranked, properly mic’d amp at any volume without the variables that normally plague such setups in a live or studio setting (inconsistent sound, mic leakage, insane volume requirements, etc.). Factory cabs include selections from our own collection of professionally produced Cab-Packs, plus selections by today’s top artists, engineers, and 3rd party IR designers like RedWirez and OwnHammer. You’ll find a superb variety of cab and speaker sizes representing the greatest brands from history and the present day. You can even create your own User Cabs, with built-in tools to capture the sound of any speaker. In addition, we offer Cab-Lab, an IR mixer and tools application for Mac and Windows, designed specifically for those who want to create their own custom IR blends (like a producer or engineer might do with different mics on the same speaker).

Exquisite Effects

In addition to industry leading amp modeling, the AX8 is an incredibly powerful and flexible multi-effects processor, with ultra-realistic recreations of classic stomp boxes and rack processor effects. Effect models can be dialed in with a single knob to make all required settings for great sound in seconds, or tweaked at the deepest level with a completely modular approach. Like our amps, effects sound and feel great, with very musical response to enhance and inspire.
