C-Axe™ Guitar Noise S

Love the C-suite but this plugin is not miraculous in daw usage for the moment !

Not worth the cash!

I have been trying everything with this plugin to make it work. Sure it stops the buzz but it completely adds an overtone harmonic to your sound which is so disappointing! Can’t seem to figure out how to stop it? So I give this a thumbs down

Use waves Rvox Instead

Kind of a scam..Send your signal chain through an instance of R-vox, and adjust the threshold to kill unwanted room tone in your signal path. It's a lot more natural that way.

A must have tool for single coil folks

I already loved the C suite for vocals & tried this.
Super clean and dynamic guitar tracks without the buzz. Used some vintage fender amps with strats and teles and the tracks come out sounding great.
Especially for a sparse mix, lets me use the guitars and amps I want

It does it's job but improvements needed

During noise suppression, it degrade the main audio signal which should not happen.

Great noise removal

C-axe is great for removing unwanted noise/hum from my guitars! Love that you can use it in console while tracking too.

Single coil goodness.

As far as I know inside of the plugins are lots of zeros and ones ferociously attacking and destroying hum while avoiding pristine sound of your telecaster.

Not impressed.
I don’t have a ton of noise in my signal path so I can’t hear hear where it’s even removing simple hiss. I didn’t realize the plug-in was so limited.
For that price point , it should be able to do more.

Enhanced performance and bug fixes are urgently needed for the app's next update

It's possible that the app isn't responding due to compatibility issues with an active pickup guitar?!?

Does nothing while using with UAD amplifier plugins

I tried the demo over some amplifier plugins from several vendors including UAD and it does nothing to the hiss. maybe a very slight change to the voicing

It does absolutely nothing

Tried this on my DAW and UAD console, but did absolutely nothing। but the C suite Vox works like a charm, and took away all the unwanted noise

Negatively Surprised

As some others have mentioned, this one does not work nearly as impressively as C Vox Suite (which I love and is indispensable to me for vocals) especially on hiss from pedal chains. In fact, all it did to the hiss was add a somewhat slightly unnatural quality to the slight background hiss - which was not perceivably attenuated. For the money required for this, it's going to need to work on hiss not just mains hum. Based on C Vox Suite I fully expected to be blown away by this and to purchase after demoing, but in fact I found it very surprisingly disappointing. Nothing works remotely as well as C Vox Suite as far as recorded vocals, but there are already far less expensive tools for guitar that will get the job done as well or better even than this for far less expenditure. In fact, I would even say that this seems unfinished and requiring further work and development - especially at its price tag but even just in general. Oh well, easy decision to give this a miss.

Decent but not as good as C vox

C suite c vox was hands down one of the biggest additions that I cant live without.
this ont he other hand is something I can easily do after tracks are recorded but it does work very well in live situations. I often do big huge budget events and sometimes I will bring one of my smaller apollos so I can use this and other UAD plugins as inserts with the digico or yamaha and this does do the trick so cant say its bad at all. just not as impressive as the c vox. that thing deserves 7 out of 5 stars

Works well

I am using C-Axe mostly with my bass guitar, where it cuts the AC hum substantially. It's not 100% gone, but it is much cleaner. I found it doesn't work to chain it with a compressor or other plugs, so I usually print only the C-Axe reduction, then add other plugs in my DAW.

Wait for it to go on sale. A solid tool for home recording.
