Mooer Noise Killer

This review may be a little unusual because a drummer writes about the pedal for guitarists / bassists.
I play drums in Alternative Rock / Industrial band where guitarist plays Fender Telecaster using Vox AC-30 amplifier, and a bass player plays Gibson Thunderbird using Trace Elliot (4x10), and both have huge pedalboard with a bunch of pedals.
While playing, everything is great, but the minute we finish playing the song, then starts an abnormal noise, howling and humming.
Anyway, I find it really unbearable, so I decided to buy them both something to kill that noise.
The name of this pedal sounded promising to me - Noise Killer :)
Unfortunately, I'm not able to give you the technical details, but what I can say is that there is no noise in pause between two songs - AT ALL!
Sound of guitar and bass remains the same and you can really find that sweet spot on the pedal knob to kill all unwanted noise, but there's still a great sound with lot of sustain.
Everyone in the band are very pleased and Mooer Noise Killer proved to be excellent for the live performance too. Using two of those, now we have really clean sound and even some more complicated and fast phrases are more clearly heard because there's no additional noise.

If you play in really loud band and you like to talk with your band members between the songs - than you need this!
Mooer Noise Killer is really a great asset!

It is a solidly built pedal with metal chassis and sturdy switches. Does not use batteries, but if you need a noise gate, that means that you have other pedals thus needing more batteries... which is heavy for the wallet, so I guess that a sensible person always uses some kind of external power. I like the size of the pedal, because it drastically reduces the space needed on the pedalboard.

One problem I have with the pedal is that it's treshold potentiometer doesn't really do anything until I crank it around -20 or -10 dB, and then it eats my sustain.

Mind you, I use high gain amps (Peavey 5150, Jet city JCA22h and H&K tubemeister 18) with OD units in front, so I should have lots and lots of sustain. I don't crank the gain all the way up, but around 4-5 which, combined with a tubescreamer-type pedal, gives a good, sturdy sound needed to play metal.

This pedal manages to eat it all. I can't find the perfect spot where it cuts the noise when I play staccato and let's enough sound to be able to let the chord ring at the end of a song, so I am forced to constantly turn it on and off which is off-putting. This problem occurs on the "soft" setting. The other one is unusable.

Long story short - it shouldn't retail for 66 euros, it works like a pedal that's half the price.

If you are single-coil player and suffer with an ungodly hiss, this will work for you perfectly. I have a setup of pretty big pedalboard, where hiss and hum are amplified with distortion, overdrive, phaser and octaver into something horrible. But this little device helps 100%.

I like it is very small (it is THAT small), it actually does not affects your sound (as long as you find the right settings) and it works real good, getting rid of hiss/hum entirely.

Tried with active and passive single coil jazz basses, piezo pickups with electric violin and electric upright bass (kontrabass), passive single-coil guitars. In each case hiss and noise is always different, but the Mooer Noise Killer can deal with each of them and does the job perfectly.

I would definitely recommend this gear to anyone.

I have other noise gates/ suppressors e.g. Boss, Artec, MXR, some of which offers more features. Fact is, I personally like simpler devices with minimal adjustments. This does the job that is expected. I cannot detect any tone alteration. The threshold knob basically works as a control for the reaction speed of the device.
I use it in a basic set up: single coil guitar (Tele or Strat), Boss Vintage Reverb, and Orange Micro Terror amp. Already at medium gain settings, the noise was far to high for my taste. I was not sure where to place a noise gate in this simple chain, as it should go after the distortion effect, before any delay (reverb). In my set up, distortion is produced by the the amp.
I just tried after the reverb effect, before the amp, and it works great. At medium gain setting, I set the threshold knob at 12 and any noise is cut as I stop playing.
I can only recommend it. Just consider it is very small (sort of cigarette pack size), so perhaps the best way to hold it to a pedal board is through plastic clips.
