Product Description

The Quad Cortex is an ultra-powerful, action-packed floor guitar amp and effects modeller from modern tone masters Neural DSP. This is the company's first entry into guitar hardware, with their previous successes in virtual amp software such as the Archetype: Nolly, Omega Ampworks and Fortin Nameless Suite.

This superb creation captures high-end guitar tones in a portable, seamlessly-intuitive piece of kit. The Quad Cortex is capable of hosting hundreds of amps and effects without breaking a sweat — thanks to the impressive 2GHz Quad-Core SHARC architecture, which is undoubtedly the future of amp modelling technology. This ludicrous amount of processing capacity provides limitless sound design possibilities!

Power Your Dream Rig

Pushing the boundaries of guitar tone has never been more accessible. The Quad Cortex's powerhouse of a processor is capable of running numerous amp models, cabinets and stereo effects interchangeably at the tap of a button.

Emulate real amp characteristics: the unique onboard biomimetic AI technology replicates any physical amplifier, overdrive, and cabinet with unprecedented likeness. Whatever you hear from a real amp, you'll hear from the Quad Cortex! Neural DSP will also continue to collaborate with leading sound designers to add more patches to the already impressive Sound Library.

Extensive Sound Library

Neural DSP boasts an ever-growing library of over 1000 guitar amp and effect algorithms. Curate your perfect tone with all Neural DSP have to offer in the Quad Cortex. The Sound Library is the go-to software for the next generation of guitar virtuosos, such as Rabea Massaad, Tosin Abasi, Plini and industry engineers like Adam "Nolly" Getgood. Like them, this is the easiest way to get your fingers on great guitar tone.

Teach your Quad Cortex new sounds. Want to take your favourite amp tone everywhere without lugging around the amp itself? Plug in a microphone and use Neural Capture to record it — you'll struggle to tell the difference between the original amp and the Quad Cortex. Built-in phantom power means you can capture your sound in optimal quality using a condenser mic too. The added bonus of the Quad Cortex's mic preamp means you can easily record a variety of instruments and spice them up with effects!

Intuitive User Interface

Not only does the Quad Cortex house one of the most extensive sound collections on the planet, but it's also one of most effortless to use. Tinker to your heart's content using the powerful parametric EQ on the 7" multi-touch display. Position virtual microphones exactly where you want on over 1000 impulse responses, with third-party IRs easy to load up as well. Drop in signal path blocks within seconds to voice your effects in unique ways, and use the rotary stomp switches to scroll through amp settings and assign 32 banks of eight presets each for instant tonal access — just like an analogue switcher.

Compact Size & All-Encompassing Connectivity

Weighing in at just under 2kg and more compact than an Apple MacBook Pro, the Neural DSP Quad Cortex is ideal for touring musicians, guitarists cutting down on gear clutter, or those with restricted space and volume levels.

Slot the Quad Cortex into any setup, either stereo or mono. It's equipped with TS, TRS and XLR ins and outs to handle everything you throw at it. Two available effects loops let you incorporate your favourite pedals into the signal chain, while MIDI connections automate switching and control every parameter within the Quad Cortex. There's even a headphone output for silent playing.

Customer Reviews

Quad Cortex is amazing. It gives me so many different options for sounds & I can easily take it anywhere.” - ⭐⭐⭐⭐⭐

[The Quad Cortex] has enabled me to reduce my amps and large pedalboard down to one small box that fits in my gig bag whilst not changing the sounds I use live at all.” - ⭐⭐⭐⭐⭐

Fantastic modeller -- truly one of the best on the market. UI is so intuitive, it just makes using the thing so much easier. There's plenty of ways you can hook this up to your gear and enjoy the plethora of effects, amps, captures, and everything else you can dream of.

The first peer to valves for my ears and fingers yet infinitely more flexible. Capable of much more than just emulation. Great UI, inspiration on tap, and loads more potential in the hardware. Deciding to democratise their tone cloud instead of monetisation is the icing on the cake.

The sounds in this unit are unreal, so usable straight out of the box. The only issue I'm having is trying to record into my DAW however that is probably my fault more than anything due to lack of experience!

Mr R Marrs15th Nov 2023

It does everything I want from the FX unit it sounds amazing and the Computer editor is fantastic. However, I would have liked the unit to be able to load via USB or perhaps even better the ability to plug in a USB stick with songs/sets & practice material that can be loaded on the fly. The 7" screen is really nice but it would be a game changer to be able to use the PC editor and replace the current somewhat meaningless FX blocks icons with your own custom icons, especially with personal FX/amp clones .... Drag & Drop thumbnail PNG picture icons etc. I am otherwise very happy with the unit, Perhaps an upgrade at a later date will see this option become available.

Quad Cortex is a game changer! It has all the good features in one small footprint; a very nice touchscreen combined with the modelling amps (like Helix or Fractal) and amp or drive pedal capturing possibility (like Kemper or ToneX). As a Kemper rack user, I'm extremely happy with Quad Cortex's flexibility and user friendliness. I'm able to create any patch within minutes by using the touchscreen. Multiple signal paths allow me to create complex presets as well as using the same unit for an acoustic duo gig. Both the vocal mic and my acoustic can be fed into Quad Cortex and signal paths are processed completely separate. It's never been a case with my Kemper as the touch screen is not intuitive enough and very old school limited signal path/stomp availabilities.
