THE GAME CHANGER FOR GUITAR AMPS? // Neural DSP Quad Cortex (vs kemper)

[@PaulDavids]

*Update: I should've mentioned the firmware is still in Beta at the moment.* The dropouts between presets will still be there on final release. Apparently its inherent to having a routing this flexible, but I was told they would be significantly less in the final release. In live scenarios using Scene Mode or Stomp mode is the way to go; although this limits you to having everything for the song on that one preset. Also doing something spontaneous which might need a preset change will always result to a dropout. I know it also happens on the Helix (not on Kemper tho), but maybe one might expect of a 'new generation' of modelers to switch presets without any audio dropouts... Maybe not. I just think it's worth mentioning. I would love to hear/see/read your thoughts! Would you ever consider getting one? Please share :)

[@p_mouse8676]

I have always the same issue with these things. I just get overwhelmed by the amount of options and possibilities. Result is that I keep fussing instead of playing.

[@tungtobak]

I appreciate your honest opinion and that it wasn't all roses although you probably recieved a review unit. I wouldn't buy one NOW anyway, as I'm currently in the process of setting up ALL my 50+ pedals, pre-amps etc, availible through old school patchbays. Like the 70s version of an Axe fx. Takes up half a room, four patchbays and seven shelves though... But I like to keep myself informed on more modern solutions. Not satisfied with how digital dirt sounds... yet. It lacks the danger.

[@RupesMcDGuitar]

Neural captured the amps better than the kemper for me. Particularly the Matchless.

[@kerninger]

Nope. This thing obviously is not ready to ship. I stay with my Fractal stuff 👍

[@aquaticborealis4877]

Have you looked at something like the Mod Duo X? It veers off into synth territory, but maybe has some powerful features you could use.

[@MarcoMontero]

Best review from the QC I’ve seen so far, you put hype out the equation and showed us a real opinion. Massive respect for that.

[@angarcm23]

Rhett Shull’s was quality too, if you haven’t seen it

[@robertjones9598]

Seconded! It's nice to hear about any limitations at all. First video I've seen voicing them.

[@missinbrain]

Yes, this and Rhett Shull’s were both constructive criticism. I mean, how are Neural going to improve if they don’t get quality and meaningful feedback like this? I actually already pre-ordered a quad Cortex because I have faith that it will continue to improve. But I agree with Paul that that is not necessarily the best way to purchase gear, and unlike most of the other videos on KZbin, this gave me a more honest expectation of what I can expect to see once it finally arrives.

[@robertjones9598]

@@missinbrain 95% of the QC videos on KZbin are clearly a massive marketing campaign. There's always some amazing new product or plug-in on the horizon to lust after. I feel I was bitten by all the BIAS hype a few years back. The Nolly plug-in is decent enough for a hobbyist like me so I'm definitely not buying the QC. But it's interesting to watch all the KZbin channels I follow blow up about it! I'm going to stick to my existing toys to make tracks. I can see how this bit of kit might be essential for the professional guitarist though.

[@roryt1985]

The review is misleading in places, especially regarding the drop out when changing presets.

[@realgoodmind]

It really is the best. It is a deluxe on roids. Then you can make it be a tweed all the way to almost plexi sounds. It does everything an amp needs to. I love it.

[@VoxTone2009]

You are probably better off with a Sky King instead. There are two separate attenuator settings, one for each channel and you can better handle the volume on both channels when switching channels on same song. It also is a little more flexible and powerful. To me it sounded better than the Imperial, although a little more expensive. The Neural sound great though. Playing live on smaller places it probably actually sound better than the amp for the audience since you can dial it in better and feed it through the PA which disperses the sound better than your amp alone which is very directional. You could also dial in the sound at home on the Imperial/Sky King or any other amp or pedal and then store that response in the Neural when playing out live on smaller spaces. Beats bending over and fiddle with the pedal knobs and the amp knobs between songs when playing live.

[@2010njdevil]

Agreed and I've used the Kemper and Quad Cortex. In a live setting, there are similarities but when you move into specialized effects, and there are a ton of the, there is no comparison: Real amp + Effectcs(examples: Keeley Monterey, Catalinbread Echorec, Catalinbread Adineko, J. Rockett Blue Note, JHS Bonsai, Vertex SSS, Ventris, Strymon Blue Sky, Neunaber reverb units, etc.....). This is why the pedal market is as strong as ever.

Man I feel like the “profiling” from the quad cortext sounds clearer and better to my ears than the kemper. But that may have been just the profiling. The kemper had more gain and more low mids, slightly woofy. It really stands out on the matchless sample. *edit* just finished the video, and Paul says the same thing. Lol. I’m not taking crazy pills.

[@ericwg73]

Neural should have paid you to review the DSP QC earlier on in their design cycle. The way you approached is was methodical, yet practical, and very thorough. The “issues” you pointed out, some more egregious than others, were all legit and I am quite certain, if fixed, would be appreciated by 99.9% of users. Thank you for the through review and comparison. BTW, I completely agree in both instances, the original amp was the hands down winner. Win I heard the Kemper’s version I thought the exact same thing...it added more gain than was naturally present. If I heard you correctly, you actually dialed it down some to make it more realistic which makes me wonder how much worse it was from the start. While I own a Kemper and think it is amazing, I wish they would have employed digital pots in the design so that it could be mated to an iPad or tablet to release more in-depth control. I wonder if Kemper has something like this in the works.

[@sketchstuffs]

This is a perfect review telling neural dsp what to add in future updates. Most of these suggestions I hope to see in the future from ndsp.

[@loopie007]

Watched the whole video and have to agree 100%. Looks like it has good potential. It would also be great if it had a "Convolution Reverb" block that had preset reverbs and installable IR's for the Convolution engine. The tone matching really gives the other modeler manufacturers a feature they will have to think hard about.

Two years ago, I chose to invest in an amp and a pedalboard. There are limitations. It’s heavy. It’s more expensive. But with the time I’ve spent learning that one rig, I’m less into finding tones from eye glaringly endless options, a/b’ing endlessly, and tweaking presets all night, to instead using what my rig does best, creating a signature tone that nobody else has, and - most importantly - playing, practicing and writing more! Haven’t looked back since

I see what people complain about, lack of effects, ui oddities, etc etc, but even with the flaws it is a ridiculously good sounding unit. You can either spend 2 minutes loading up an amazing sounding preset, or spend an hour tweaking it and routing eq's and effects in cool ways and it will sound even better. IMO it is the no question the best out there compared to earlier releases of fractal or line6 or kempers. And comparing to their current firmware's, the QC holds its own with more pro's than con's.

Thanks Paul, that was a very informative video. I use Helix but never use the distortions as my ears tell me that real pedals into the front are more responsive and clearer, maybe placebo but to me the most important feature of these units is the quality of their amp simulation and IR capabilities, seems like they all throw in loads of FX blocks to make it an all-in one solution but the distortions, reverbs and delays fall short. Any comparison you do always leaves me feeling that the real amp has the edge. Have a great day!

To be honest: I think the very cheap modelers are already there. Of course they are nowhere near a Kemper or a Line6 Helix, but the Ampero and Mooer GE250 are a godsend for budget-constrained people who just want to record. Imo they get 80-90% close to the "big" modelers and in a mix that's definitely close enough. To think of the features and different tones you can get for under $400 right now is insane when compared to 20 years ago.

[@moskitoh2651]

@@fretboardrunner Also with the Pod Go you are already in a budget domain and get the Helix modelling...

[@Jh0st]

Such a helpful review - others go through features and options, but this really demonstrates the most important aspect: TONE! The amp/QC/Kemper comparison was really the clincher: With lower gain sounds - like with the beautiful Tone King amp - the QC falls completely flat IMO. It lacks a complexity in harmonics - the Kemper does a fair job to its credit. Because of this, there's no sense of chimy/resistance in any of the QC amp models: it's like the sound is being being filtered through a spongy piece of Wonder Bread... Like the original amp tones, there should be shimmering harmonics at the attack of the notes (a metaphor is the crispy crust of artisan bread) that gradually falls away, but the QC has the same flat harmonics all the way through. I don't think any amount of EQ will fix this: the lack of complex harmonics was evident in all the comparisons. So glad I saw this before making a purchase that I would regret!

[@mistermoan5693]

Thanks for the video Paul, really enjoyed the walk-through; I especially appreciated the highlights on the missing points, which are quite useful in my opinion to whoever is watching the video within the idea of getting one of these. It reminded me of when I started comparing the AXE-FX and the Helix, almost 3 years ago. The Helix was relatively young at the time and the AXE-FX III was in pre-order, if I'm not wrong. Anyway, finally last year I pulled the trigger and went for Helix: honestly, I couldn't be happier. In the meanwhile, Line6 addressed a lot of issues Helix had when I started looking at it. So, TL:DR; maybe the QC is the new outsider, we'll see. For now, considering your review and few other things I've read around, to me still looks like a promising project, but we're not 'just there'... yet. Best!

[@brunoweber5107]

Basically, the amp sounds like the amp, the QC has slightly more high frequencies, while the Kemper has a bit more bottom end. Honestly, I feel this is so close that a bit of EQ on any unit will make it sounds like the other one and vice versa. Being a Kemper owner, I can't say that soundwise the QC is any better or worse. It is a matter of EQ and taste. The QC interface is million years ahead of the Kemper; but that's not really important for me. I wouldn't sell the Kemper for it, but if I didn't have the Kemper I would surely put the QC into the equation. Something is missing in the video though, which to me made the biggest difference when I compared the Helix to the Kemper: how does it feel, in the hands?

Dang- you got the yellow one!! (I was wondering who was the lucky owner!) Perfection. Love that Novo guitar ;-) Oh yeah- good review of the Quad also

[@jennekke]

I just can’t see myself playing with this live as an effects unit. Maybe if you have a couple guitarists with their own pedal boards you could do 2 inputs in and have their own outputs. 1 amp model setup for 2 guitarists would be sweet.

[@Siggy152]

this is the first reviw of this device i have seen and i guess everybody and their parents in the guitar influencer world got one and is creating content like this. which of course isn't a bad thing! I just really think people should take note (in general) how this was presented. Reviews are never 100% objective, they are affected by the taste of the reviewer. Reviews are calibrated against existing things that have been used and proven for years. A new product most likely will have flaws at launch but some of that come down to your personal preference, some will be fixed in the future. This seemed very honest and i think the advice NEURAL will have gained from this will make this a much better product. I guess many people that receive a sponsorship like this will try to mitigate the flaws to look better to the advertisers by telling their audience what a great piece of equipment they are advertising. But in the end - this is much more helpful both to the consumer and to the company. So hat off, well done!

[@PaulDavids]

This isn't a sponsorship, they did not give me the device.

"Never buy something based on promised software updates" - I guess you don't have the Cyberpunk 2077 (yet)? :D

[@saywhat9158]

You mean, never buy based on promised release features if you are using CyberPunk as an example as you simply have no idea of the level and quality of updates that they will eventually provide at this point and if Witcher is an indicator, your example will make your point look dumb.

I sold my Kemper after waiting patiently for 6 years for them to release the editor, only to find it was not worth the wait. Never again.....

[@jklmopqtstuvwxyz5349]

@@digitalchris6681 the one thing which is too late to update is the tiny window. And as I said all of them need help from real pedals. Except 2. The Yamaha 100hd double modeler and the Iridium.

I’m curious to see where the QC is at when it’s time to replace my beloved Helix.

[@r.llynch4124]

Its already there

[@lockedowng]

Seems like the helix 3.0 update keeps it interesting and pretty close. If you play metal, neural is pulling away.

[@felipealonso8409]

Agree, Helix seems more reliable so far.

[@viktorbalko213]

Amazing review, being a Neural DSP plugin-user I'm strongly considering the Quad Cortex, but now you've given me things to think about regarding the kemper. But your final point about the cortex being more "future proof" is I think why I might buy it over the kemper bc idk what the kepmer's going to be like compare to the cortes in 5 years when DAWs get updated as well..

[@KillerBackingTracks]

Drop out is massive no no! But the captured tones did sound very good! I do love the plugins from Neural so will see how this develops over time! Cheers Paul 🙌

[@AlextheBant]

Dropout happens on all current existing units like helix and axefx though. That's why scènes are used

[@flagmuffin1221]

Dropout happens with every unit, not just Neural's.

[@rejuvenator8966]

This is old beta firmware. Check out new Dave Navarro vid to see how preset change sounds mid song now. No audible gap at all.

[@blackmetalbreadstick]

From reading the comments I expected you to tear this thing apart but after watching the video you pretty much share the same opinions as some of the other reviews. I’m super stoked for this thing, especially at this price.

[@billylindsay5712]

I'm switching to the quad cortex, great demo, this backed up what I had already thought and I have already listed my Kemper and remote.

Well it’s been delayed again so you may want to wait.

I love how that there is no need to rebuild your factory of production line in order to accommodate changes and tweaks based on the users' requests. It's a matter of changing the code, even if it is quite sophisticated. Good times.

Maybe I'm just getting older, but this seems so complicated. My brain can't handle too much other than turning something on and off and maybe fiddling with a couple of knobs.

[@Noodleboy56]

The Kemper, the Helix and Fractal are all way more complicated.

[@ahighervibe4086]

Im the same...but FORCED MYSELF to learn when I bought a Helix LT. I am SO GLAD I DID! Bottom line: We can still learn, it just takes more time and patience than when we were younger. On a positive note, when we do force learn as I like to call it, I feel like the content is more truly absorbed because of the forced focus inherently involved with learning complicated things post age 50. ugh lol

With digital it's always "the next best, revolutionary" device. Still, I prefer your Matchless.

[@Paul_Lenard_Ewing]

The Matchless will still be sitting there in 5 years and the Neural DSP will be used to hold open the door. DSP stands for 'Door Stop Product.'

[@breakingnewground1]

Probably the best review so far. Good job!

[@andreasschaefer8613]

The kemper has years to develop it's effects, they weren't as good in the beginning, quad cortex just starts (and it's not really available since now!), so I'm sure that the quality will increase in time. I'll change my kemper stage for the quad cortex, because of the stunning operation and controls on it, it's much more intuitive! And the format of the device for me is also a reason, I use it in studio, were the Toaster is nice, but the stage really not - the quad cortex can easily fit on my desk and also under my feet, that's amazing. At the end it's unbelievable that the kemper in it's way has no competitor (for me) in all the years of conquer the market, so I think a little bit competition might be good for the users ;-)
