Critic Reviews

Neural DSP Quad Cortex Review 2024 — HoneySonic Production Co.

honeysonic.com

The Neural DSP Quad Cortex showcases impressive capabilities, boasting extensive I/O options and a user-friendly desktop editor. However, it falls short in some key areas, such as the limited built-in effects and the inability to easily integrate essential expression pedals, which may frustrate users seeking a streamlined setup. While the sounds produced are generally solid, comparisons with competitors like Kemper reveal that the tone may not quite match what some players desire. Ultimately, the Quad Cortex is a powerful tool for those ready to invest time in learning its intricacies, but it might not be a one-size-fits-all solution for everyone.

Quad Cortex: The Long-Term Review | guitarguitar

guitarguitar.co.uk

The Neural DSP Quad Cortex shines as the best-sounding digital modeller on the market, offering exceptional tones and a wealth of new amps and pedals post-firmware update. However, its user interface remains a hurdle, with unintuitive graphics and frustrating patch-changing delays. While the sound quality is top-notch, the complexity can be overwhelming, especially for those used to simpler systems. The addition of Scene mode alleviates some concerns about seamless transitions, but the overall experience can still feel convoluted. If you prioritize sound above all, the Quad Cortex is a stellar choice, but be prepared for a learning curve.

Is the Neural DSP Quad Cortex worth it? - Guitar Chalk

guitarchalk.com

The Neural DSP Quad Cortex, while packed with features, is deemed overpriced and unnecessary by the reviewer. At $1,699, it offers extensive amp modeling and effects that many musicians may never fully utilize. The sentiment suggests that aspiring guitarists should focus on mastering a few core sounds rather than getting lost in an overwhelming array of options. The review criticizes the trend toward digital versatility, arguing that it detracts from developing a personal sound. Ultimately, the Quad Cortex is labeled as a "monstrosity" that encourages superficial exploration rather than genuine musical growth, making it a poor investment for serious players.

One pedal that makes the difference!

I used to think that the more “landmines” a guitarist had in front of him on stage, the better he was... OK, that's complete nonsense, of course, but nevertheless, that idea stuck in my head for many years. Well, with this Quad Cortex from NEURAL, the Finns have shown us how it's done, and I think they've done an excellent job! Everything can always be improved, and there are still a few areas here that could be tweaked, but all in all, I don't really need any other device to create my sounds! The standard presets, combined with all the free downloads from the QC community and, if you like, a plug-in or two, are more than enough to generate great sounds across all genres and save them in playlists. Besides the QC, my pedalboard only has a wireless receiver, a permanently displaying tuner, an expression pedal, and the MIDI remote control from Luminite. That's it!

There are some great sounds here but...

I think simply put this was released far too early and they promised too much. Way overhyped. Poor midi control. Pretty disappointing overall but there's potential.

Does everything that a Helix, Kemper, or Axe-Fx does but does but in a smaller, cleaner package. The UI is so brain dead simple that any two year old who can work an ipad can figure it out.
