IK Multimedia TONEX vs Neural DSP Nano Cortex - Which Mini-Modeler Should You Choose?
Capture, profiling, modeling - the market for compact guitar processors has gotten crowded, and two names keep coming up in every discussion: IK Multimedia TONEX and Neural DSP Nano Cortex. Both promise the same thing: the real sound of a tube amp without the tube amp, in a housing that fits on a pedalboard. They approach it differently, though, and those differences are exactly what decide which device is right for you.
This is not a "better versus worse" ranking. Both devices sound great, and in a finished mix the difference between them lives in the nuances rather than in different leagues. The choice comes down to how you work: whether you want to make your own captures on the go, how much a desktop editor matters to you, how many effects you need, and how much you want to spend. Let us break it down step by step, without the marketing.
Table of contents
First a small clarification, because there is a lot of confusion around it. TONEX is not a single device but a whole family. There is the full-size IK Multimedia TONEX Pedal with a screen, the miniature IK Multimedia TONEX ONE, and a bass edition too. When we put TONEX against the Neural DSP Nano Cortex, the fairest match is the full-size IK Multimedia TONEX Pedal - it is the closest rival in price and features. We will treat the IK Multimedia TONEX ONE as the most affordable way into the category.
What is IK Multimedia TONEX?
IK Multimedia TONEX Pedal is built around AI Machine Modeling, which means capturing the sound of a specific, real piece of gear rather than hand-coding a circuit. IK Multimedia calls the result a Tone Model. The pedal plays back ready Tone Models and lets you store up to 150 presets across 50 banks.
TONEX's biggest strength is its open ecosystem. The box includes TONEX MAX and AmpliTube 5 software, and through the ToneNET platform you get access to tens of thousands of Tone Models, many of them free. You keep your own tones on your computer and freely swap them with other players. The full-size IK Multimedia TONEX Pedal also has a small, readable display, works as a USB audio interface, and is hand-assembled in Italy. Treat the onboard effects (noise gate, EQ, compressor, reverbs, and delays and modulations added through updates) as a bonus, though, because the heart of the device is still the amp and cab.
At Wired Tunes the IK Multimedia TONEX Pedal costs around 306 EUR (current sale price).
What is Neural DSP Nano Cortex?
Neural DSP Nano Cortex is the younger sibling of the flagship Neural DSP Quad Cortex. It uses Neural Capture technology, and its biggest asset is that it creates captures directly on the device, with no computer and no internet. You connect an amp, start the process, and in about five minutes you have a finished clone that you can A/B against the original on the spot.
Neural DSP Nano Cortex has no screen, because the idea is that detailed editing happens in the Cortex Cloud app over Bluetooth. The signal path is fixed and made up of seven modules: two pre-effect slots, the Neural Capture module, an IR loader, and three post-effect slots. After the big, free NanOS 2.0 update it gained more than 40 new effects (drives, modulations, EQs, fuzzes), and a late-2025 update brought Neural Capture V2 with improved dynamics. The unit weighs only 620 g, works as a 24-bit/48 kHz audio interface, and can be powered from a power bank over USB-C.
At Wired Tunes the Neural DSP Nano Cortex costs around 560 EUR.
Capturing: on the device or via a computer?
This is where the most important line between these two pedals runs.
Neural DSP Nano Cortex captures on its own, on the unit itself. You do not need a computer or any extra rigging. For someone who genuinely wants to capture their own amps in different places, that is often the deciding argument, and it is exactly what users praise on the forums.
IK Multimedia TONEX Pedal captures differently - in software on a computer. You need an audio interface to record the amp into the TONEX software, where the Tone Model is created. That is less convenient on the road, but it has two upsides. First, in most A/B comparisons (so-called null tests) TONEX comes out slightly more accurate. Second, the ecosystem is fully open: you keep your tones on disk and buy or download other people's Tone Models from anyone, including for free on ToneNET.
The takeaway is simple. If you really plan to capture your own gear, Neural DSP Nano Cortex is more convenient. If accuracy and the freedom to swap models matter more, you are closer to IK Multimedia TONEX Pedal. Let us be honest, though: the vast majority of guitarists will never make a single capture themselves and will use ready tones instead. For them this point matters less than it seems.
Ready tones, effects and signal chain
Out of the box, IK Multimedia TONEX Pedal looks more generous. The pedal ships with a thousand ready Tone Models plus access to a huge community library. For someone who just wants to plug in and play, that is a real plus, because the odds of finding the tone you want ready-made are very high.
Neural DSP Nano Cortex relies on the Cortex Cloud, which also holds plenty of captures, including the fresh factory Neural Capture V2 ones. The quality of the official clones is high, but in sheer volume and openness the library still trails the IK Multimedia ecosystem.
An important practical difference concerns the signal chain. Neural DSP Nano Cortex holds two effects before the amp and three after it, and it cannot run two captures at once - so you cannot kick in a captured booster on one switch over a captured amp on another. After its updates, IK Multimedia TONEX Pedal also has more effects and slots, and its small screen makes working without a computer easier. Many players simply keep it as an "amp in a pedal" and build the rest of the chain from their own analog effects.
Size, controls and workflow
The full-size IK Multimedia TONEX Pedal is bigger, with three footswitches and a small display. Neural DSP Nano Cortex is smaller, but it has no screen at all and only two footswitches.
And here a real weakness of Neural DSP Nano Cortex surfaces for some users: editing happens only through the mobile app, there is no full desktop editor. Some people do not care, others are genuinely annoyed by it, especially if they are used to dialing in tones at a computer. IK Multimedia TONEX Pedal has an editor on both desktop and mobile, although navigating the IK Multimedia ecosystem is often called clunky. So convenience cuts both ways: with Neural DSP the capture process and app are nicer, but you are tied to your phone; with IK Multimedia you get a full desktop editor but less friendly navigation.

Which mini-modeler should you choose?
Without crowning a single winner, because depending on your needs a different one wins.
Neural DSP Nano Cortex (around 560 EUR) - choose it if capturing your own amps on the go without a computer matters to you, you like the Neural DSP ecosystem, and dialing everything in from a phone does not bother you. It is the most convenient standalone capture device in its class.
IK Multimedia TONEX Pedal (around 306 EUR) - choose it if maximum accuracy of the finished capture, a huge open tone library straight out of the box, a desktop editor, and a lower price matter more, and you already use your own effects anyway.
IK Multimedia TONEX ONE (around 129 EUR) - consider it if you want the cheapest and smallest way to get excellent amp tone and you are fine with minimal controls and a simpler set of effects.
FAQ
Does the Neural DSP Nano Cortex capture without a computer?
Yes. It is one of its main strengths. Neural DSP Nano Cortex creates captures directly on the device, with no computer or internet, in about five minutes, after which you can compare the result against the original. With the IK Multimedia TONEX Pedal, the capture is created in software on a computer.
Which sounds better - IK Multimedia TONEX or Neural DSP Nano Cortex?
Both sound very good and are very close to each other in a finished mix. In A/B comparisons TONEX is sometimes a touch more precise in reproducing the source, but it is a difference of nuance, not of class. The real choice is about workflow, ecosystem and price, not about tone quality itself.
How does the IK Multimedia TONEX Pedal differ from the TONEX ONE?
IK Multimedia TONEX Pedal is bigger, with a small display, three footswitches, and more room for presets and control. IK Multimedia TONEX ONE is the miniature version at roughly half the price, with a single footswitch and app-based control. The amp tone quality is very similar; the differences are mainly about ease of use and the number of features.
Does the Neural DSP Nano Cortex have a desktop editor?
Currently no. Editing the Neural DSP Nano Cortex is done through the Cortex Cloud mobile app over Bluetooth. If you prefer to dial in tones at a computer, the IK Multimedia TONEX Pedal with its Windows and Mac editor will be more convenient.
Do these devices work as an audio interface for recording?
Yes, both of them. You connect either the Neural DSP Nano Cortex or the IK Multimedia TONEX Pedal over USB and record your tone straight into a DAW. The Nano Cortex runs at 24-bit/48 kHz and can also be powered from a power bank over USB-C, which makes silent practice and recording anywhere easier.
Can a mini-modeler replace a real tube amp?
For recording, rehearsals and most gigs, for many players yes. Capture technology has matured enough that in a mix the tone can be hard to tell apart from a real amp. The differences usually come down to playing feel and simplicity of use rather than the tone itself. The best way is to hear it for yourself and compare a few units live.
Summary
There is no universally correct answer here, only the answer that is right for you. Neural DSP Nano Cortex gives you standalone capturing and a convenient app, while IK Multimedia TONEX Pedal gives you greater accuracy, an open library and a lower price. Neither is a bad choice, and the difference lies not in tone quality but in workflow and how you plan to use the device.
