The Ins and Outs of Great Tone

 Fractal Audio is known for building audiophile-grade signal paths into guitar products, and the AM4 is no exception. Its low-noise “secret sauce” instrument input with Auto-Z impedance authentically loads your guitar pickups, while balanced outputs preserve signal integrity when going direct. An analog stereo insert provides Send and Return jacks for outboard gear, and a high-quality headphone amp supports silent practice and monitoring. Two Pedal ports each accept an expression pedal or external footswitch. For digital connectivity, AM4 includes S/PDIF I/O, USB-C for MIDI and 4×4 audio with re-amping, and 3.5 mm MIDI In and Out. The AM4 is powered by the included 9V DC 1.5A adapter.
