The Sound of Fractal Audio
Legendary Amp Modeling and Speaker Simulation
The centerpiece of the FM9 is “Cygnus”, the latest version of Fractal Audio’s critically acclaimed amp modeling technology. Cygnus uses our proprietary SpectrumTrack™ technology, which improves the response of amp models across the entire range of input levels, especially for amps with cascaded gain stages. The result is truer and more dynamic “voicing,” plus exceptionally satisfying “chugs.”
The FM9’s two amp blocks each have four channels which can run any of 280+ vintage, modern, and original models covering everything from pristine clean, to edge of breakup, from crunchy overdrive to modern distortion to insane gain.
The FM9 also includes the entire Ultra-Res™ speaker cabinet collection from the Axe-Fx III, with 2,200+ “Factory” cabs including selections from the today’s best producers, plus 1,024 “User” locations for loading your own Impulse Responses (“IRs”).
A Suite of Stompbox and Studio Effects
The FM9 is an outstanding multi-effects unit, packed with hundreds of incredible stomp box and studio effects, with accurate recreations of many classics, plus exciting originals. Our effects have been vetted and endorsed by the world’s greatest guitar players.
Selections include 57+ drive pedal models, dozens of delays, numerous choruses, flangers, phasers, tremolo, and other modulation effects, 50+ reverb types from classic spring to real spaces and beyond, multiple compressors, wahs, EQs and filters, a 2-minute looper, an entire suite of pitch effects including detune, harmony, and virtual capo, plus rotary, synth, “plex” effects including shimmer, and many more.
One of each of the available block types of the FM9 is shown below. Note that almost all of these can be used multiple times in every preset. A complete count can be found in the Blocks Guide.

The Power of Impressive Presets
The FM9 is the most powerful floor unit Fractal Audio has ever created with a four-core DSP architecture. Its presets—created on a “grid” from “blocks” as shown below—can utilize an impressive number of blocks to provide capabilities rivaling or surpassing those of a gigantic analog rig.
