Vulgar Display of Power

Quad Cortex is the most powerful floor modeler on the planet. With 2GHz of dedicated DSP from its Quad-Core SHARC architecture, this ludicrous amount of processing capacity provides limitless sound design possibilities.

Neural Capture

Capture, share and download your favorite rigs’ sounds.
Equipped with our unique biomimetic AI technology, Quad Cortex can learn and replicate the sonic characteristics of any physical amplifier, overdrive, and cabinet with unprecedented accuracy.

Unlike any other, our sophisticated neural network algorithm perceives sound akin to human perception, making it the most natural-sounding capture solution on the planet.

We are collaborating with some of the best producers and sound designers to provide an ever-growing collection of free rig captures in addition to our full-circuit models.

As good as it gets

Quad Cortex packs a vast amount of state-of-the-art emulations of your favorite gear with unprecedented accuracy and unbelievably natural dynamic response.

An ever-expanding collection of guitar and bass algorithms

50+ Amps
70+ Effects 
1000+ IRs


With over 1000 perfectly captured impulse responses, Quad Cortex ships with one of the most extensive IR collections on the planet – and it is the only of its kind equipped with virtual microphones that can be positioned around the speaker like in a real studio. Third-party IRs are extremely easy to load.

Absolute control at your fingertips. Taking full advantage of the 7” multi-touch display, our parametric EQ is intuitive and fun to use.

Unparalleled Intuitiveness & Flexibility

- With its massive 7” multi-touch display, Quad Cortex is unbelievably easy to use. Effortlessly create even the most complex signal paths.

- Drag-and-drop blocks to change the order or routing in seconds.

- Visualize and control the settings of inputs and outputs with one swipe.

Switching Modes

Switching modes couldn’t be easier, providing easy access to features and switch customization.

Stomp Mode: Assign and activate any block in a rig to a footswitch like you would with an analog pedalboard.

Scene Mode: Select any footswitch to instantly activate and control the settings of any number of blocks within a rig.

Preset Mode: Instant access to 8 virtual rigs.

Unbelievably Compact

Using advanced mechanical design and manufacturing techniques, we managed to not only build the most powerful floor modeler/multi-effects processor on the planet, we also managed to pack it all in an extremely compact format.


Quad Cortex comes in a gorgeous anodized aluminum unibody, with laser engraved graphics that never fade.

Our multi-touch display is armored with a chemically strengthened protective glass and a reinforced touch sensor panel.

Anodized aluminum unibody

Use Quad Cortex as a high-fidelity interface, with Cirrus Logic codecs and an ultra-low-latency USB audio transmission.

1.Dual Combo Inputs: TS, TRS, and XLR, variable impedance and level controls, built-in microphone preamps, and phantom power supplies.

2.Dual effects-loops: ideal for embedding external mono, or stereo effects into your signal chain, as well as additional input/output jacks.

3.1/4” Output jacks: two mono, balanced (TRS) outputs provide pristine sound quality and optimal noise performance.

4.XLR Output jacks: two mono, balanced XLR output jacks

5.Headphone Output: ideal for quiet practicing.

6.MIDI In, Out/Thru: receive and send MIDI messages to automate switching and control of every parameter in Quad Cortex, as well as controlling other units.

7.Dual Expression Inputs: connect up to two expression pedals. They can be assigned to control wahs, volume, as well as pitch-shifting algorithms

8.USB: Ultra-low latency audio transmission, firmware updates, MIDI, and more.

9.11 stainless steel stomp+rotary actuators allow for switching and rotational control (just like the footswitches and knobs you are used to, but unbreakable).

Neural CNS

Seamlessly Integrate Cortex with your favorite devices

Explore and share endless presets on the cloud using Neural CNS Mobile. It syncs up to your device, and with Quad Cortex’s built-in WiFi module all the presets are beamed wirelessly.

Cortex Desktop Controller allows you to control the floor unit in real-time, as well as direct access to Neural CNS for exploring, sharing and downloading presets with the Cortex users community

So finally I write my review here. QC by Neural DSP is hands down the best device deserving of a 21st-century guitar processor tag. Yes, there are limitations and improvements to be made but true to its Neural DNA, this device is meant to upgrade itself seamlessly over time. The fact that it CAN & WILL, is the best feeling I have as a proud owner of my QC. My personal dealing with folks at Neural DSP has left me in awe of how prompt and genuinely helpful they are towards their customer. For me, they have set a benchmark in customer support and troubleshooting. The sounds out of this device are superb and in my opinion at par or better than competitors. Any nitpicking comparisons are just futile and a waste of time. If you can afford it, grab it. EMI could be great too. Where it goes far beyond the competition is the ease of use and the seamless utility of presets and captures through its cloud integration. The touchscreen is very handy and I can't see myself using any other UI ever again. QC has set a standard for all devices from other company's to follow. That itself says enough about a young company that has time and again brought us smiles with their brilliant plugins. And soon our plugins will be integrated into the QC. Anybody who owns their plugins has no reason to look at other hardware. I really appreciate this strategy and more importantly kudos to the fact that they delivered on it with their product design and performance. The form factor is a dream design. The finish is uber quality. The portability is a no brainer for a bedroom or a pro guitarist. I could keep raving on and on about this beauty. And I know I will wish I had written more in ode to this madness. The wait was more than worth it. Gift yourself this creation.
