Fractal Audio announced the AM4 Amp Modeler on November 1, 2025, and says it is now shipping in the USA and Canada at $6991. The maker describes it as its most compact all-in-one unit1.
The AM4 combines Fractal's Cygnus X-3 amp modeling, DynaCab speaker simulation, UltraRes user cab support and effects, built on what the maker calls the same technology as the Axe-Fx III1. Fractal lists 240+ amp models, 45+ DynaCabs, 325+ effects, 104 presets with four scenes each, and four amp-and-cab channels per preset with gapless switching1. A new Amp Mode selects channels from the footswitches; the unit has four footswitches and five modes1. Guitar World reports four configurable footswitches and four universal parameter knobs2.
The rear panel carries a low-noise Auto-Z instrument input, balanced TRS outputs, a stereo analog insert with Send and Return jacks, S/PDIF I/O, USB-C for MIDI and 4x4 audio with re-amping, 3.5 mm MIDI In and Out, two pedal ports and a headphone amp1. Power comes from an included 9V DC 1.5A adapter1. AM4-Edit is a free Mac/PC editor and librarian1.
The sources differ on the modeling version: Fractal's page says Cygnus X-31, while Guitar World says Cygnus X-22.
"The AM4 is a compact powerhouse. It's perfect on a pedalboard, sits neatly on a studio desk"
Guitar World gives context on price: the Fractal FM3 at $1,099, the FM9 at $1,799, the Line 6 HX Stomp at $699 and the IK Multimedia TONEX at $4292.
