Neural DSP Quad Cortex 5-stars Reviews
Quad CoreBlimey
Tbh I was introduced by a proper guitarist who tours with his QC and says Kempers are converting over. I didn’t know what that meant (I do now). I’m still getting my head around the programming or navigation and captures but I love the presets and the captures my pal loaded up for me.
It’s real real close to the real mic, amp deal. In fact I sometimes struggle to get my mic, amp and pedal setup on point especially under time constraints. It sounds analogue and punchy and funky and rock driven and burning and broken without the usual digital tell tale signs. Really the best thing out there for pros on guitars.
Perfekt für Bass & Gitarre
Insgesamt alle Erwartungen erfüllt.
Plugins lassen sich bis zur nativen Unterstützung profilen - lediglich selbst mit CorOS 2.0.0 immer noch keine Möglichkeit, die Eingangsimpedanz und Empfindlichkeit pro Patch abzuspeichern. Das nervt ein wenig, wenn man zwischen Instrumenten mit unterschiedlich heissen PUs wechselt. Aber auch da kann man einfach Input 1 für "Hot" und Input 2 für "Cold" nutzen; sowie an einigen Amps das auch auch der Fall ist.
What an amazing tool!
I am an owner of many multi fx products, and have extensively used amp modelers from Line 6, Fractal audio, and Positive Grid. I have had my eye on the Quad Cortex for some time now, especially since I have noticed a few artists using them at live concerts with amazing tones coming through the PA.
So I just received my new QC unit, and right out of the box I was already very impressed by the amp tones, as well as the variety of effects in the factory presets. But once I began editing my own patches the real quality became very apparent quickly. Building patches is so easy, and I have figured out how to save scenes and tweak virtually every setting with expression pedals and stomp modes. The routing and blending possibilities are just endless, and the layout is very intuitive. I especially love the ability to turn the foot switches like amp knobs, as well as numerically enter exact parameter settings with a touch of one finger on the screen.
In all honesty, having access to hundreds of real tube amps through my job at a major backline company, I have grown very used to the real life organic sound of all of the included amp and cab models. These captures are so good, responsive to playing attack and volume changes just like the real deal. It is unbelievably realistic, yet so much better with all the effects and routing options. I can hardly wait to create some captures of my own!
Another aspect that I am really enjoying is playing my acoustic guitars through the QC. With just a little compressor, a subtle eq, some chorus and reverb, the acoustics are sounding absolutely stunning. I normally use a Fishman Aura to add some simulated mic tones, so I will attempt to capture the Aura pedal and blend it into these patch signals for added realism, although puting the Aura in the fx loop is also a viable option. Ahh... so many options with the QC! I am very happy and excited to create more music with this incredible tool!
It needs no explanation
I saw a bad comment... ;(
However, Its dont need to explain this product after using it myself.
1. A really simple way to operate it
2. Noise? 12V 3A grounded adapter will solve everything. Change the adapter.
3. Sound? You can do it. And theres a lot of presetting.
The basic sound itself is cooool..
Do you like iPhone or Samsung? That could be the answer.
You should experience it yourself. You don't have to listen to anyone else.
The best unit
Excellent quality and sound! Super easy to use!
Sick device
Gorgeous device, bought it after fractal, insanely satisfied. Compact dimensions, many possibilities, a huge amount of memory for solving any problems (I have more than enough))
We play with the whole group in one device, also all the familiar musicians switched to Quad cortex)
Great pedal for performing
It is very great experience to use it in gigs.
DSP was very powerful, I could have 4 chain of all effects and IR all functional at the same time.
Scene mode is a great design, I can play whole gigs without switching presets.
Sound quality was great.
Excellent Product
I really enjoy making music with the QC. I’ve created multiple recordings and have lots of presets created for my style. The community is also very strong. You can literally find any type of amp cab combo under the sun.
Amazing
This thing is ahead of competition. As owner of kemper the sound and the feel is way better... The only problem is the power supply.. that is noisy.. you have to find other solutions as cioks 7...
Great
It sounds great and it's easy to use.
Moved from fractal axe fx 2 and love it
I have to say the amp modeling and capture are so detailed that nt axe fx2 felt real bad compared to QC. I still miss the effects from fractal but other than that , eveything is perfect.
Perfect product
Headline is describe everything on single word
UrzÄ dzenie z innej planety
Jak dla mnie to QC ma wszystko czego kiedykolwiek mógłbym potrzebować. Rewelacyjna jakość wykonania, dziecinnie prosta obsługa, oraz super brzmiące na dzień dobry presety. A to dopiero początek zabawy....
Quad cortex
Good sound and control
User friendly
I've had it for almost a year now and it has two big pluses: sound quality and ease of use.
It is so easy to move around the blocks and build complex rigs really fast. I'm usually runnig two guitar lines with a detuned line for a bass emulation all in a single preset and it can handle it with no issue.
As for the sound quality, it is what you can expect at this top price range. I've had other simmilar devices (Kemper) and it is simply undistinguishable regarding the captures/profiles.
As for the downsides, the preset exchange on the app is a bit messy, you cannot download and share single presets "offline" as you can with other similar devices. So far they have been quite consistent with the updates.
I'm still curious about the build quality. So far so good but have not had any gigs yet.
Would definietly recommend.
Best modeller out there
If you are searching for a modeller that sounds real, search no more, this is the thing. Of course I can find difference in sound and feel from the real thing, but it is pretty damn close, super light to carry and super convenient to use
Sounds, looks, and feels greate !
A joy to use !
Fast shipping & great product
Highly recommended product if you want a lot of different amp tones. The effects are somewhat lacking at the moment but the captures respond incredibly well to modulation effects. Has replaced most of my pedals but not my phaser and delays yet.
Love this thing, first modeller i kept.
it's a great build and easy to use product, it's the first modeller i kept "AWESOME SOUND"! I use it with a Line 6 Powercab & 250ohm dt 770 pro headphone. But i would recommend a headphone with lesser ohm!!! This product is still receiving updates every 2 months and the sounds still get better and better.
Quad cortex
This machine is amazing.
All reviews are true. sound is form another galaxy. only going through all the presets you can find sounds for everything you want to play. diving in means you need to be a "pro" due to the deep simulation.
noticed some flaws. volume button sometimes seems to be moving up and down one value. once i fired it up it had great noise in the output (xlr and ts) but after a restart everything was fine. one more time the screen seemed to be touched even though i didnt touch. cleaned it and again was fine. could be software issues but imo are minor and never noticed one again.
Superb purchase and i am super happy.
