What Is the Neural DSP Quad Cortex Mini?

The Quad Cortex Mini is a compact amp modeller and multi-effects processor for guitar and bass. Announced at NAMM in January 2026, Neural DSP described it as “no compromise, just smaller”: the complete Quad Cortex experience in a body more than 50% smaller than the original.

Since the original Quad Cortex arrived in 2020, the Helsinki-based company has been one of the leading names in amp modelling, up against Line 6 Helix, Fractal Audio, IK Multimedia and others. Its mix of an intuitive interface and top-tier modelling has kept it at the centre of the conversation.

The Mini sits between the full Quad Cortex and the smaller Nano Cortex. It runs the same CorOS software on the same processing hardware, and keeps the 7-inch multitouch display, its most striking feature. If the flagship tempted you but was too big for your board, this is Neural DSP’s answer.

Price: €1,299

Full Specs at a Glance

Design and Build Quality

The first thing you notice is the glass. The 7-inch touchscreen takes up almost the entire top of the pedal, with a footswitch in each corner, all in an anodised aluminium unibody. Nothing else on the market looks like it.

Understandably, the glass makes some guitarists nervous: stomp switches and glass don’t usually mix. Neural DSP says it did extensive durability testing, and reviewers who have stomped on it in boots report that it holds up very well. At NAMM, brand ambassador John Connearn called it “borderline unbreakable”, and YouTuber Ola Englund reportedly used his as a trampoline without any damage.

The aluminium body feels solid. At 1.5 kg it’s heavier than it looks but easy to fit on a pedalboard or desk. The locking power connector is a smart touch for live use. The four stainless steel footswitches twist as well as click, working as both switches and parameter knobs.

One thing to know: the unit is flat rather than angled like the full Quad Cortex, so reaching the top two switches takes a slight stretch. Not a dealbreaker, but worth knowing.

Sound Quality and Amp Modelling

This is where the Mini earns its price. With more than 90 amp models, from Fender-style cleans through Marshall-style crunch to EVH-style high gain, the range is huge. More importantly, the models react to your playing: roll back the volume and the tone cleans up like a real amp, switch pickups and you hear the difference you’d expect.

Reviewers from Sweetwater, MusicRadar and Guitar World agree that at matched levels the Mini sounds identical to the full-size Quad Cortex. That’s the benchmark that matters most, and it passes.

The effects are just as strong. Modulation, delay and reverb are detailed and musical. Drive models are good overall, though some reviewers feel the overdrive and fuzz emulations are a small step behind the rest of the library. A minor point on an otherwise excellent platform.

Bass players are well covered too, which makes it a real all-in-one rig if you play both.

Neural Capture V1 and V2

Neural Capture is what has set Neural DSP apart since 2020. It uses a neural network to capture the sound and feel of a real amp, cabinet or drive pedal, including how it responds to your playing.

The Mini supports both versions:

• Neural Capture V1 runs entirely on the device, offline. Fast and accurate for most amps, cabinets and overdrives.
• Neural Capture V2 is processed in Cortex Cloud using a higher-resolution algorithm. It takes longer, but it’s far more accurate with complex, touch-sensitive gear like fuzzes, compressors and very dynamic valve amps, capturing details like sag, bloom and volume-knob clean-up that V1 can miss.

In Sweetwater’s hands-on test with a Blackstar HT40, V1 sounded like a high-quality amp sim. V2 was described as “downright uncanny”: the reviewer couldn’t tell the capture from the real amp, by ear or by feel.

The Mini also ships with more than 2,000 factory captures, and free access to thousands more in the Cortex Cloud community library. Even if you don’t own an amp worth capturing, you have a huge palette from day one.

Usability and Interface

The Mini runs full CorOS, the same software as the flagship. The Grid view, with its drag-and-drop signal chain, is all there. You can build complex parallel signal paths and adjust everything by touch or with the footswitch encoders.

With four footswitches instead of the original’s eleven, Neural DSP had to get creative. There’s Preset mode for switching whole rigs, Scene mode for seamless changes within a preset, Stomp mode for a classic pedalboard layout and Hybrid mode to mix them, plus a clean Gig View for the stage.

There’s also a new way of editing with your feet: twist the footswitch encoders to scroll through and adjust parameters, a bit like an Etch-a-Sketch. Guitar World liked it enough to want it on the full-size unit.

The honest caveat: four switches mean more tapping and mode-switching than eleven. If you need instant access to lots of individual effects during a set, the difference is real. Most gigging players will adapt, but think about your live workflow before you buy.

Presets and backups move freely between the Mini and the full Quad Cortex, so if you already own a QC you can bring all your sounds across.

I/O and Connectivity

For such a small unit, the connectivity is impressive:

• Input 1: 1/4″ TS instrument input
• Input 2 / capture input: XLR and 1/4″ TRS combo with phantom power, for mics as well as instruments
• Dual FX loops: shared on one TRS jack. Use a TRS cable for one loop, or a TRS insert cable for both
• Expression input: 1/4″ TRS (a second is available via MIDI)
• XLR outputs: two balanced outputs for a PA or interface
• 1/4″ outputs: two more for amps or flexible routing
• MIDI: 3.5 mm TRS in and out/thru (Type A)
• USB-C: 16-channel audio interface (8 in, 8 out) plus firmware and data
• Headphones: 3.5 mm for silent practice
• Wi-Fi: for Cortex Cloud and updates

Compared with the full Quad Cortex, the trade-offs are a shared TRS jack for the FX loops, 3.5 mm MIDI instead of full-size DIN, and one fewer combo input. Minor for most players; worth considering if you run a complex MIDI rig or lots of external effects. If you need cables for your rig, have a look at our guitar cables.

Quad Cortex Mini vs Full Quad Cortex

If you gig with lots of live footswitching and a complex MIDI rig, the full Quad Cortex is still the more practical stage tool. As a studio tool, desktop unit or compact fly rig, the Mini is arguably better: small, with a built-in audio interface and easy to use on a desk.

Quad Cortex Mini vs Nano Cortex

These are really different products. The Nano Cortex (launched in 2024, around €500) is a compact pedal without a screen, built around playing back Neural Captures with a simplified effects chain.

The Mini is a full multi-effects processor with a touchscreen, amp models, the complete effects library, dual signal paths and full CorOS. If you want a small pedal for captures, the Nano Cortex still makes sense. If you want everything the Quad Cortex does in a smaller box, get the Mini.

Verdict: Should You Buy the Quad Cortex Mini?

The Quad Cortex Mini is one of the most impressive pieces of guitar gear of 2026. Neural DSP has taken a large, feature-packed flagship and squeezed it into a compact unit without any real compromise in sound or power. The tones match the full Quad Cortex, the touchscreen is there, both versions of Neural Capture are there, and the CorOS workflow carries over completely.

It’s ideal if you want the full Quad Cortex experience but your pedalboard, desk, fly rig or gig bag doesn’t have room for it. It’s especially strong for recording. Live players who rely on lots of real-time footswitching will need to adapt, but for most, four multi-function switches are workable.

At €1,299 it isn’t cheap. But for flagship processing, world-class modelling, the full effects library, Neural Capture, a built-in interface and the best touchscreen in the modeller market, the value stacks up. The glass top and the reduced footswitch count are the only real trade-offs, and neither is a dealbreaker.

Our rating: 4.5 / 5

The Quad Cortex Mini is exactly what thousands of guitarists asked for, and Neural DSP has delivered it without cutting corners.

Where to Buy the Quad Cortex Mini in the Netherlands
