FM3 - Amp Modeler / Multi-FX / Floor Unit

Write a Review
Out of Stock until late September
NOTE: Due to high demand and the ongoing global semiconductor shortage, the FM3 is currently out of stock. We expect to re-supply in late September. If you would like to be notified, please send an email to with the subject "FM3 WAIT LIST". (If you do not enter this subject, we can't notify you.)


The FM3 is an all-in-one amp modeler, effects processor and foot controller. It features our latest ARES amp modeling, a technology developed for the award-winning Axe-Fx III. Ares recreates the sound — and the equally important feel — of real tube amps, with 265+ models offering an impressive range of clean tones, elusive “edge of breakup”, and everything from warm, touch-sensitive overdrive to face-melting modern distortion.

The FM3 also includes the entire speaker cab impulse response (“IR”) collection from the Axe-Fx III, with a stunning 2,200+ “Factory” choices and 1,024 “User” locations to store custom sounds from free or commercial producers.

As a multi-effects unit, FM3 truly excels. It includes a superb selection of Fractal Audio’s state-of-the-art effect algorithms. All of the essentials and many exciting innovations are on board: dazzling drive pedals, dozens of delays, reverbs, compressors, EQs, phasers, flangers and other modulation effects, a looper, and much more.

The FM3 also features 4x4 USB Audio capability for both Mac and PC. This lets the FM3 double as the hub of a portable recording studio for playback, recording, re-amping, and more.

The FM3 is an extremely flexible and versatile foot controller with switch and layout capabilities based on our FC Controllers. Each footswitch has its own mini LCD display to show the function of the switch, plus a variable color LED ring which shows the category and status of the switch. Those who wish for more footswitches can use FASLINK™ to connect one or two FC-6 or FC-12 controllers. These integrate seamlessly with onboard switches and also offer additional switch/pedal jacks.

Whether you want the pure simplicity of a great guitar straight in to a classic amp, or to venture into totally unexplored sonic territory, the FM3 delivers the legendary Fractal Audio experience — and fits easily into a backpack*

    First up: FractalAudio - thanks for the fast shipping! Verdict on the FM3: I dialled in a competent Rectifier sound in less than 10min. I never managed such good sound with any modellers, incl. software modellers, I used before - and definitely not in less than 10min. I was sceptical about all the Axe/FM3 hype, but this stuff is legit and just sounds great. And all that for less money than a decent valve head. Keep it up!

    I have been waiting forever before finally jumping into the Fractal world. The FM3 made this decision easy. The sounds are out of this world REAL and versatility is off the charts. I wasted so much I'm catching up with the FM3

    I was used to using a competitor’s modeling product for years and bought an FM3 out of curiosity. I figured I would sell it if I didn’t like it. I’m keeping the FM3. Incredible sound quality and feel. Really enjoying the unit!

    Light but Strong

    I definitely enjoyed my first moments with the FM3. The presets still sound amazing, the portability is perfect for throwing this in a backpack with a laptop for a portable setup, and it looks beautiful. I only rate it 4 stars since it is a bit trickier when going from Axe Fx 3 to this due to the CPU change. However, aside from that, I still believe this is a solid portable option and product from Fractal!

    FM3 Floor Unit

    Posted by Shannon Bump on 15th Mar 2021

    Impressive array of amp and cabinet models! Effects seem rock solid in comparison to both stomp boxes and other integrated processor units. The unit is incredibly powerful while remaining easy to use. The depth of the user controls is mind boggling! I am still experimenting creating both programs existing tones and exploring new ones as well. Thank you Fractal Audio for pushing my audio boundaries to incredible new heights.
