Fractal Audio FM9 — Your Standard Working Horse of a Guitar Processor
FM9 is the newest release since the popular FM3 model hit the market in April of 2019. The current generation represents the evolution of the previous one, featuring more footswitches, I/O and DSP power.
It also offers increased performance thanks to the 4 DSP cores, which is more than its predecessor featured.
The processor has a large display with easy-to-navigate controls. The device shares the layout of buttons and rotary encoders with the previous model FM3, but adds on to it with more footswitches — there are 9 of those with their own vari-color LED rings.
On top of that, each footswitch has an LCD display that indicates the current assignment.
In terms of ports, you won’t miss out on anything with this guitar processor. It offers 1/4” instrument input, two stereo pairs of 1/4” jacks, and to top it off — main stereo output with both XLR and 1/4” outs. And it even has a headphone jack.
There are also 48k SPDIF and 5-pin MIDI in and outs. FASLINK II port lets you connect an external switch or expression pedal: the manufacturer even sells first-party Fractal Audio FC-12 and FC-6 foot controllers.
You can record the sound with a built-in USB audio interface that has 8 channel recording and playback.
Fractal Audio FM9 is built on a system called amp blocks. Each block has 4 channels that run more than 280 amp models. In addition, the device has Fractal’s entire cabinet collection built-in with more than 2200+ cabs. You can upload your own impulse responses using 1024 locations.
Now, let’s talk effects. This guitar processor offers a ton of freedom in terms of sound algorithms. Here you can make use of 57 overdrive pedals, 50 reverbs, and a wide variety of delays.
Want some more? Fractal Audio FM9 has you covered. It covers all the bases with chorus, flanger, phaser, tremolo, wah, EQ, filter, and pitch effects.
- Great control versatility
- Higher cost.
- Nothing to set it apart from the competition.
Helix Line 6 — A True Powerhouse
So, Line 6 responds to the newest guitar processor offerings from Fractal with its dual-DSP Helix, allowing it to process 4 discrete stereo paths. The device is packed to the brim with an array of amps, cab, and effect simulations to help you bring out the best in your guitar playing.
The guitar processor offers a sturdy and beefy enclosure. The front panel houses a large 6,2” LCD display and an array of footswitches with illuminated labels, knobs, and a programmable expression/volume pedal.
The I/O covers all of the needs an electric guitar player might have: it has 2 expression inputs and a CV/expression output; external amp; guitar, aux, and mic inputs; XLR, 1/4”, and headphone outputs; 4 sends and returns; Variax input; MIDI input, output, and Thru; S/PDIF input and output; AES/EBU or L6 Link output; USB port.
The Helix offers 1024 preset locations that you can organize in 8 setlists containing 32 banks, each having 4 presets. Your preset can have 4 stereo paths, with each of those including 8 blocks of amps and effects.
To amplify your sound, you can rely on 41 modeled amps, 7 bass amps, 30 cabs, 16 mics, and 80 effects. The joystick makes it much easier to edit the sound, and touch-sensitive footswitches let you get to the parameter adjustment much faster before applying it to the sound.
The treadle and the footswitches can be completely adjusted to your liking with two operating modes: Preset and Stomp. The first mode chooses the preset while the second one turns the effect on and off.
- Good accuracy.
- Great for indie and alternative rock.
- Lower price.
- Might not suit heavy genres.
- Some users report windows 10 driver issues.
