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.

A Real Problem Solver!

I recently had to relocate my home studio to a new neighborhood. Unfortunately, my only option for setting back up was a garage apartment that was located directly under some power lines feeding the entire neighborhood. And to make matters worse, there is a cellphone tower located about 100 yards from this spot. I had battled sound and emf noise to my exhaustion. I had all but given up hope and even had to stop recording because the noise that my guitar would pick up was so intrusive that it was not even usable. Noise gates were useless. external filters and power conditioning did some but not enough. the main source of intrusion was from the guitar pickups. I recently decided to try the C-Axe with no real hope of it actually working. I was blown away! It has been so successful at removing the emf from the guitar signal that I have been able to resume recording again! There are certain times of the day when the cell tower leaks in a little but it is so minor that you really have to be listening very close to even tell it was happening. This new plug-in has solved a major issue that has plagued me to doom. I know that my situation is not ideal for a studio and most people would just locate elsewhere but I was stubborn and refused to move again. If this can solve a major problem like mine then I would feel safe suggesting to anyone who is considering this plug-in that it is well worth it! Yes, it's expensive, but the technology within validates the price. I had already spent much more on things that just didn't work. This was truly money well spent!

Cool tool just not as consistent as c-vox

Glad I got this one as it does work just not as consistently as c-vox does. Still awesome and does help

Works Like It Should

It does just what it says. Perfect for my Strat and Telecaster.

It works

It will remove amp noise or hiss and does not interfere with amp sound, expensive but got it on Christmas deal.If you record live amps you will need this

My favourite noise suppressor

This little guy gets rid of that unwanted hum from vintage single coils. I didn't realise how much I needed this plugin until I turned it on. And it's so easy to use. Don't think I'd ever record guitar without it. Get it!

Finally! Noise suppression that works!

As someone that's always been plagued by noisy single-coil pickups, this plugin is a lifesaver. I can finally roll up into the gain I desire and not worry about inter-note hums and noise, and just the sounds in my head! I already rely on C-Suite to manage the fan noise in my vocal booth, and now C-Axe will take up a permanent home in my guitar Insert chain. Well done!!!

This is a high level. You need this plugin.

Luckily, I managed to buy this plugin at a discount. It was the right decision. The purity of the guitar sound will please you. You will be delighted with this. Try it, I recommend it!!!

Works great

I have Electric interference problems with my guitar and PC being in the same small room. So i tried this to see if it would help and it worked a treat taking out the high pitched noise as well at the hum. The audio seems transparent, i didn't feel like it changed my tone. If i reviewed this for the quality of the plugin alone it would be 5/5 but I'm Only giving 3 stars as i think the price is disgusting for what it is but as i got it in a bundle sale which worked out i paid around £47 i felt i paid what it should have sold for without a sale. Easy to use, it does the job well and it's very low latency so great for real time playing. It really should have been included in the vocal version of this product

This plug in shines in getting rid of single-coil hum from Stratocasters and telecasters. It adapts to the noise—even if it is the lower level noise from a humbucker equipped guitar—and cancels it out. I have it on the UAD console app, and it’s like magic. Yet unlike a gate, it doesn’t mess with the attack of the note. Highly recommended, especially if you play single coils.

Like magic! But magic ≠ perfect.

I grabbed both this and the C-vox and they are highly recommended! It's crazy how all this can be done live on the fly; it's like magic! BUT like with anything that is removing unwanted things like noise, pushing it will eventually start affecting the tone, it's inevitable! I've had great results with this - but sometimes I could tell it's affecting the tone, like a metallic sound effect when playing with distorted guitars. I have a preset called "don't let go", where I let the plugin sample the hum while I'm touching the strings, because if I let go, the hum/buzzing is *really* loud and C-axe will have to really fight to kill that noise. For jamming that's ok.

Great if you're tracking, jamming or playing live. But I had great results removing the hum in post using a cheaper plugin that doesn't start with R.
Then there's the price. Yikes!
But 9/10 are probably getting this during a sale, like I did.
It's a bit DSP-hungry, so if you're using a solo like me, you will probably not be able to use your regular guitar chain + it's taking up a slot.

I am curious to see if they will work on improving and updating this, or if this is the final version.

But all in all, it's really good and if you are having problems like me, you will be very happy to flip this on and hear the noise virtually disappear!
