Usually Ships Within 1 Business Day
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 CYGNUS amp modeling, a technology developed for the award-winning Axe-Fx III. The FM3 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*

    FM3 Perfect Size and Capabilities

    Posted by Scott Kaszyk on 1st Mar 2022

    This thing sounded amazing right out of the box on both my studio monitors and my Deluxe Reverb (with the FM3 Amp and Can disabled easily in global settings). I've tried the other "line" of modeling amps and was disgusted by their poor sound quality and didn't want to spend the rest of my life tweaking settings to get something usable. This device is also super flexible, lots of inputs/outputs. I was easily able to add a controller for wah/volume and figured out how to set up a double switch without much trouble.

    FM3 Amp Modeler

    Posted by Joel Brown on 21st Jan 2022

    If you want the best tone, feel, and flexibility this is the product. Nothing else comes close. It can be as simple or as complex as you like. Take your time and learn what it can do. At first I struggled a little but once I came up to speed I quickly found it did everything I wanted and more. I've never had my guitar sound and feel this good.

    New user to fm3, so far an outstanding product. SO MUCH better than Headrush Pedalboard! One note to new users is to go to sign up for Cooper Carters FM3 Masterclass it is well worth the price.

    Fractal FM3

    Posted by Jason Hyde on 11th Jan 2022

    I've had my FM3 unit since March of 2021, and I am 100% satisfied with my purchase. It meets or exceeds every single expectation that I had, and it was also the final step in downsizing my once-cumbersome 4x12/rack/pedalboard live setup. Now my entire rig, literally, fits in the front seat of my car. Zero regrets, and I'm never going back to a full amp/cabinet rig again. FIVE STARS!!!

    I am a bass player in a working band, and I've gone thru several versions of bass rigs I've the past 10 years or so. Most things have been bulky, modular systems that fall short in one way or another. My most reliable system to date has been an ampeg tube combo, but last summer I had my tubes go bad, and with the addition of in ear monitors, I decided to give an amp modeler a shot. Got my FM3 on Saturday and brought it to a friend's house to dial in some tones and get acquainted with it. I can't tell you how much fun it is to get a great sound with this unit. I'm amazed at what this can do and I hope to play several hundred shows with it. Can't wait for rehearsal tomorrow!

    Incredible Product!

    Posted by Paul C on 9th Jan 2022

    I have tried modeling hardware and software with decent results. Fractal feels miles ahead of the pack. In my opinion, this is largely because of how fractal hardware handles the analog input and gain stage. "In the box" plugins simply cannot do that. FM3 is surprisingly great as a pedal platform as well. Very impressed.
