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.

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.

[@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.

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.

[@camreese1444]

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

[@ThmsGlnn]

Amen

[@MBEG89]

Thats not what this is for. These are designed for pro touring musicians who cant carry 10 different amps every show. Now you dont need a rig from 3 albums ago to sound like that, you just load it up and play.

[@Hassan-Alnajjar]

Nah, eventually you have to go back to the pedal board.

[@derkoettner]

You are totally right!!!

[@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?

[@jasonalexander5253]

@Bruno Weber yes, how did it feel-great question.

[@jeffneiman4635]

Basically, when the AxeFxII, Helix, and Kemper came out we reached the point where there are marginal differences between high-end modeling units. Additionally, once they're in a mix it's nearly impossible to tell a difference. Finally, put all the units through the same IR and there's almost no chance a listener can tell any difference. Buy a proper modeler and just play!

[@felipealonso8409]

Those QC higher frequencies makes it sound less thicker than what the original is.

[@JustinShreds]

Killer review! Neural should be watching and making notes - nothing is ever perfect but this thing is pretty damn sweet regardless. Looking forward to receiving mine 🙌🏼

[@Returnality]

This is the first time I have ever listened to a digital unit and not been able to tell that it's digital. It sounds SO freaking natural. That said, though, some of the bugs here are just unacceptable for something at this price point. I'll wait to see if they patch them out before I consider saving up for something like this. Killer review!

[@dustinmbox]

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.

[@sketchstuffs]

So after watching this video, and others, I decided to pre-order one. I got it about a month ago and I am actually blown away by it. 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. Can't wait to see how this thing develops over the years!

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 ;-)

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.

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.

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.

The pricetag puts these toys out of the hands of many players, but it is a seriously professional piece of gear. If you take what you do seriously and for the long term..... you may want to get a tool like this. If you use one or two sounds and that is how you prefer to perform and record, don't bother.

I believe the quad cortex did exactly what it was supposed to.

Every frequency is going to react differently and all a modelling software can do is recognize paterns.

Eyhh... you had the noise gate activated on the Kemper when you demonstrated rolled back volume on the guitar! That creates a somewhat peculiar attack :-P

[@jklmopqtstuvwxyz5349]

Hmm I roll back on the Kemper and helix no noise gate and they just don’t react like an amp when I’m using high gain.

[@RuslanCherryMissing]

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.

[@mistermoan5693]

This might be better than my Kemper (and probably is). But that does not make my Kemper worse. Still love it and I hope that every next piece of gear means progression. Not Quad Core, not Kemper, but progression and still being able to enjoy what you've got. As for your review. Honest and great! Thanks! Useful for the Neural team too.

[@algorithm007ify]

Kemper has a better ecosystem....the Kone/Kabinet, inbuilt power amps, larger selection of profiles, better effects, etc.

[@anthanth3805]

Thank you Paul. Easily the most informative review I've seen on the Quad Cortex. Great work.

[@MintyBitesBack]

Good review. I was really excited by this but it looks like it’s still in beta mode for now. Think I’ll stick with Helix for another year or so and see how it progresses...

[@CharfishDesign]

Love this objective review. Gonna be waiting a while to see how the QC updates as time goes on. Appreciate it, Paul!

[@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.

[@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.

[@kcussrebutuemos4815]

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

[@billylindsay5712]

@@kcussrebutuemos4815 Decision already made, the Kemper is listed and will go when it sells. Delays are what we deal with in the time of covid.

Paul, ik ben blij dat je deze review hebt gedaan. Heel eerlijk en oprecht. Dank daarvoor, het is iets wat ik vaak mis van andere reviewers. Helemaal top 👊🏻

Nicely done. I especially loved the tune and tone from <a href="#" class="seekto" data-time="1035">17:15</a> to <a href="#" class="seekto" data-time="1067">17:47</a>...beautiful.

[@NagoyaHouseHead]

All the other guitar KZbin's rated the QC over the Kemper but Paul rated the Kemper over the QC and guess what ? I go with Paul every time.

[@19Cluj]

Hi, I just would like to address 2 of the concerns you raised. The output issue. I understand how annoying it can be, but I guess the simple fix is to use xlr to trs cables. There’s no benefit in using xlr over trs for line level signal, and this way you can still use the ground lifting option which doesn’t exist for outputs 3/4. And for the swipe down, I understand it’s already used for creating splitter/mixer.

[@ludlow555]

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.

[@bernardhossmoto]

Very good real world review. Wow, the Kemper really is 10 years old now! Man, I was on the original Beta tester program and owned one for a year or so.

[@teagenbinder948]

Noice! I got your Next Level Playing course! Really helping!

[@riccovrea841]

Paul by far the best review of a piece of gear ever on KZbin!

[@james1939-s1c]

Guitar rolled back ay 18 minutes, reason I will continue to use a tube amp. I have never used a modeling device that is able to mimic those dynamics.

[@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.

[@JC3D]

Axe FX is the way to go IMO

[@hogger88]

I think I agree , holding off buying an FM3 as hopefully they will release a newer bigger version of a floor modeler with more dsp.

[@GertvanderDoes]

@宏洋高嶋 everything uses IR's. Helix, Fractal, Atomic, all the others. Even Kemper, it makes their own when profiling..

[@brianmaycoverbrianmayfrien975]

Fm3 feels and sounds great , tuve un kemper y lo vendí a los 2 días , el fm3 es perfecto , el cortex sinceramente es más publicidad de todo lo que ofrece sobre lo que realmente suena .....

[@Factless_Wonder]

I like those constructive comments about the inner menus swiping up to access. The comments about a live gig not having xlr are legit. I Hope that they listen and improve

[@vinski19]

This is the most rounded, deepest review of the Quad Cortex I've seen yet...great job, Paul. What's the song at <a href="#" class="seekto" data-time="1005">16:45</a>, please? Sounds familiar but I've gone blank. Thanks.

[@HomeWreckerPickups]

I see Paul has digested the Paganini licks into his riffing now.

[@JGorg8]

Man, the Kemper in this comparison REALLY has that added compression into it. Thanks for the comparision

[@marcvianello511]

Nice to see an influencer not blowing smoke up this units arse he really has exposed some flaws in the unit I wonder why rebea didn't pick up on any of this or any of the others ummm!! great review nicely done

[@JANDRE08]

it seams like Rebea got his unit for free way before anyone else. He seems like a cool dude but overrated guitarist.

[@Hexspa]

Thank you for going A B C - B A C. Usually A is the control and it's easier to compare the variables on the riff change.

[@sandrabecht4489]

Let‘s be honest: 99,999% of us players don‘t new gear. We need to practise more👍🇩🇪

[@KelsterVonShredster]

Thanks for giving us a real review and not jumping on the hyper hype bus! It will take years for this product to reach true maturity just like it did for Fractal & Kemper

[@AnomieTrain]

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

[@darvinreed2314]

I'll stick with my gt1000

[@jammer777]

Sounds like the Iridium would be perfect for you.

[@joshb6384]

Sounds great coming out of both. That’s because you’re a phenomenal player, and an inspiration for us all. Keep up the good work dude

Hello Paul. I admire your content. This is a Perfect guitar pedal. Yes, I would love to buy, but the dollar rate in our country is very high. :) Thank you for your hard work my friend. Take care of yourself.

[@RetroDaydreamMusic]

As someone who is a tone chaser. I Had a Quad Cortex and ended up getting a FM3 instead. For me the FM3 gets better low and high gain tones as well is louded with a insane amount of great effects. Though if I was in a band I would probaly get the Quad Cortex just because 3 people can use it at the same time which is nuts!

[@208414]

The audio dropouts and clicking when changing presets and scenes is something that needs attention. Thanks for the in-depth review!

[@GodzillaGoesGaga]

Big time right ? Having seamless transitions is a must.

[@DaviSiqueiraSilva]

The absence of some of the other KZbinrs (we all know who they are) blindly praising the QC in the comments section of this video is just remarkable. Also, where's the comment from the guys at Neural DSP? Is it buried somewhere here or they simply didn't want to comment on a slightly unfavorable review? Thanks for keeping it real, Paul!
