Quad Cortex: All Your Amps, All Your Effects, All At Once
This isn't just another floorboard; it's a ridiculous, reality-bending amount of power that will make your old tube amp question its very existence. The Neural DSP Quad Cortex is a vulgar display of power, a complete sonic ecosystem that puts an entire studio's worth of amps, cabs, and effects under your feet—and it has the brains to capture the soul of any piece of gear you own. This is the end of compromise.
Neural Capture: Your Amp's Digital Twin
Let's talk about the magic trick. Neural Capture is a freakishly smart, biomimetic AI that doesn't just "profile" your gear—it learns it. Like a human ear, it perceives the sound, feel, and dynamic response of any physical amplifier, overdrive pedal, or cabinet, and replicates it with terrifying accuracy. Want to take your priceless vintage combo on the road without it leaving your house? Capture it. Love the sound of your buddy's modded overdrive? Capture it. You can then share your captures, download captures from a worldwide community, and access a growing collection from top producers, all for free. It’s the most natural-sounding capture solution on the planet, full stop.
An Interface So Simple, It's Almost Unfair
Forget menu diving. The Quad Cortex is built around a massive 7-inch multi-touch display that works just like your smartphone. Want to build a signal chain? Just drag and drop amps, pedals, and effects wherever you want them. Need to tweak the EQ? Pinch and zoom on the powerful parametric EQ like you're looking at a photo. Everything is visual, intuitive, and lightning-fast. You can switch between Stomp, Scene, and Preset modes to control your rig exactly how you want, while the brilliant Gig View makes your entire screen a giant, at-a-glance layout of your footswitch assignments. It's so easy to use, it feels like cheating.
The Brains and the Brawn
All this power is packed into an impossibly compact and gorgeous anodized aluminum unibody that’s built for the road. The footswitches aren't just switches; they're stainless steel stomp+rotary actuators, meaning you can stomp on them or turn them to tweak parameters, and they’re basically indestructible. Under the hood, a 2GHz Quad-Core SHARC processor runs the show, letting you stack four amp models, stereo reverbs, and a whole clown car of other effects without even breaking a sweat. With pro-level I/O, including dual FX loops, mic preamps, and a class-leading USB audio interface, the Quad Cortex is the unbreakable, unblinking hub of your entire rig.

This thing is pretty awesome,
This thing is pretty awesome, but. . . The problem with these digital devices is they're difficult to access on the fly, when compared to pedals. This interface is probably the best one I've seen given the touchscreen and the rotary buttons, so you don't need a laptop to access settings like you wou...
