Fractal Audio · effects unit
The Fractal Audio FM3 is a compact floor-based amp modeling and multi-effects processor built around Fractal three-core Griffin DSP and Cygnus amp modeling technology, offering over 300 amp models plus all factory cabinet impulse responses from the flagship Axe-Fx III alongside 1,024 user cab slots. It includes drive pedals, delays, reverbs, compressors, EQs, and modulation effects, with three programmable footswitches, MIDI I O, S PDIF, and doubles as a 4x4 USB audio interface for recording and reamping. Its amp modeling is built to capture both the tone and playing feel of real tube amps across clean, crunch, and high-gain territory. It suits gigging and touring guitarists wanting Axe-Fx III level modeling quality in a smaller, floor-friendly footprint, as well as studio users needing a compact reamping and interface solution.
