FM3

Fm3 is a model designation used in several technology products, most notably the Fractal Audio Systems FM3, a compact floor-based guitar effects processor. The FM3 combines amp and cabinet modeling, multi-effects, and flexible routing in a portable unit designed for live performance and studio use. It relies on Fractal’s digital signal processing to reproduce a wide range of guitar and bass tones, including clean, crunch, and high-gain configurations, with modeled amplifiers, speaker cabinets, microphone placements, and effect blocks such as delays, reverbs, modulation, and dynamics.

The device emphasizes a streamlined workflow suitable for on-stage use, providing a front-panel interface for real-time editing and presets, as well as a software editor for deeper programming. Users can build complex signal chains by stacking amp models, cabinet simulations, and effects blocks, enabling versatile tones and easy tone-switching during performances. The FM3 supports MIDI control and an expression pedal input for hands-free parameter adjustment, and it includes USB connectivity for audio streaming, data transfer, and software updates.

In addition to its musical applications, fm3 as a designation appears in other, less-documented contexts, where it may refer to different products or codes. However, the Fractal Audio FM3 remains the most widely recognized reference associated with the name, particularly among guitarists seeking a portable yet capable modeler for live rigs and studio work.
