For players who want studio-grade amp modelling and effects in a compact, pedalboard-friendly format.
The Fractal Audio AM4 is a compact amp modeler and multi-effects processor designed to deliver professional-grade tone in a streamlined, portable unit. Built on the same core technology as Fractal’s flagship systems, it brings high-end sound and flexibility into a more accessible and intuitive platform.
Designed to sit comfortably on a pedalboard or desktop setup, the AM4 offers a clean and efficient workflow—combining powerful performance with ease of use.
Tone & Character
Powered by Fractal Audio’s Cygnus X-3 amp modelling, the AM4 delivers highly responsive, realistic amp tones—from pristine cleans to saturated high-gain sounds—with excellent dynamic feel and articulation.
With over 240+ amp models, 45+ speaker cabinet simulations, and a wide range of effects, it offers a complete tonal ecosystem within a single unit.
Functionality & Flexibility
The AM4 features a streamlined architecture designed for fast, intuitive use, with four channels per preset and gapless switching for seamless performance transitions.
Integrated DynaCab™ speaker simulation allows real-time mic positioning, while support for third-party impulse responses provides further tonal customization.
With USB audio, MIDI, and S/PDIF connectivity, it functions as both a live performance unit and a compact recording interface.
Build & Usability
Housed in a rugged, pedalboard-friendly format, the AM4 is built for both stage and studio environments. Its interface is designed to feel familiar—closer to traditional amps and pedals—while still offering deeper control when needed.
Despite its compact size, it delivers the full Fractal experience in a simplified form, making it ideal for players who want high-end tone without complex routing systems.
