tom.schryer.9's review"Very helpful ally against single-coil hum"

Boss NS-2 Noise Suppressor
I love my NS-2. Single-coil pickups (IMHO) have a purer sinusoidal waveform than humbuckers since a humbucker has two rows of pickups which are slightly out of phase but then combined. However, single-coils are noisy (60-cycle hum from lights, etc.). What to do? NS-2! Techy point: the unit can be noisy (less effective) with some power supplies so be careful about that (see below).


nobs are a little mysterious but not really a problem. I use it so my soft passages are free of 60-cycle hum. Ever hear Buddy Guy live? Quiet passages can be real attention getters.


Mainly 2 "Strat" clones: both single-coiled ChordBenders, one in Nashville tuning (which I think of as "mandolin sound" & just have to use as sonic spice).


Boss regulates the price but some NS-2 dealers offer free stuff (like a power supply that actually gets along with the NS-2) so include “free” when you Google for where to buy one. The knobs control a lowest usable volume & once your signal falls below that you get silence so balance that limitation with noise control. Very sturdy. My effects board has a noise controller but the NS-2 is much better.

King Loudness's review"Fair enough noise gate"

Boss NS-2 Noise Suppressor
The BOSS NS-2 has been one of the standard "go to" noise gates or suppressors since the late eighties. It's pretty simple to use and very common to see in guitar rigs regardless of style or gear used, just to cut down on that ever present hum and buzz that many players are fighting in their rigs. It has a threshold control, as well as a rate control and a knob to select whether you want the pedal to reduce your noise or act as a mute, very cool feature for sure. Otherwise it's pretty standard BOSS as far as the features go and there isn't much to say about it. The construction is the standard stomp box fare and it really has a durable feel that will last for a long time.


The setup of this pedal is either easy or difficult depending on your angle. I'm a huge fan of the ISP Decimator gate, which has a more gradual sweep and doesn't cut your tone off so staccato. That's really the biggest thing I find with setting this up. It can be more difficult to get it so it doesn't completely choke off your sound with its gate, whereas the ISP unit is more about keeping the tone and just removing the noise and not cutting off your signal. That being said, each has its place and if you want that sort of very abrupt cutoff, the NS-2 is a great pedal for thaat.


This pedal is really best used in situations where either you're in a noisy place playing, or if your rig is high gain and has a lot of inherent noise issues. This particular noise gate would probably be of interest to a lot of thrash metal or death metal players where you can get those nice quick cutoffs and not be left with a wall of noise. Many players actually prefer the feel of the BOSS unit, but for me where I play more of a standard hard rock style and like having my tones sustain, I prefer a unit like the ISP which has that more gradual cutoff for the notes.


All in all I think the BOSS NS-2 is a decent noise gate for someone looking for a basic stomp box noise suppressor with a nice fast cutoff and more controls for adjustment. If you just want something to get rid of hum and don't need that fast attack, I would have a look at the ISP Technologies Decimator which does that job well and has served me quite nicely for a few years now. It really depends what you're looking for, but for most applications the NS-2 will do fine.

Hatsubai's review"Solid noise gate"

Boss NS-2 Noise Suppressor
Noise is one of the things we higher gain players battle as we play on stage. One of the most annoying things out there is when your guitar starts to ring out and feedback, especially when you're in a metal band with fast start/stop riffs. Boss has been one of the go-to noise gate solutions for quite awhile now. The pedal features a decay, threshold and special selector knob to select between two different settings. You can also run this both in front of the amp AND in the loop at the same time.


The pedal itself is housed in one of the best housings out there. You won't have to worry about this thing breaking on you while you're on tour. The knobs are also laid out fairly decently, although I don't know why they spaced them the way they did. The manual is fairly clear as to what everything does, but I find that this pedal lacks versatility. I'll get to that later, but the pedal itself is simple enough to set up and go.


The pedal does what it should do. It cuts the feedback and lets you have silence while you're not playing. However, the issue is that this pedal sucks tone. It's one of the major things wrong with this pedal. Another one is that I seem to have issues with this when compared to the ISP Decimator. Where as the Decimator can do some great staccato gating, this seems to have some issues with the gating for whatever reason. The good thing is that this pedal can work in both the front and loop at the same time, but you'll want to be careful about ground loops. ISP now has a G-String which does the same thing, so I question whether this is really necessary today.


The pedal itself is solid, but there are better things on the market today. I vastly prefer the ISP stuff to the Boss stuff when it comes to noise gates. The Boss technology is just too outdated and doesn't sound as natural as the ISP does for the type of music I play. If you can get one of these cheap, get it. Otherwise, just get an ISP.

iamqman's review"Noise gate looper"

Boss NS-2 Noise Suppressor
Boss has a pedal for every possible operation in music. They should be making a pedal that plays the guitar for you. Boss is like the iphone app store. When they say there's an app for that...well there is Boos pedal for that. They have effects pedals for just about anything and everything that you can think of and have done versions and new editions of a lot of those pedals. If you can't find something that you need I am almost sure Boss has a pedal for it.

This pedal is simply a noise gate. Not too much to talk about other than it limits the amount of noise one would experience in their guitar rig. The reason for a pedal like this is to give guitar players a limiter on how much noise they will experience in their signal chain. This pedal can be hooked up in two different ways. You can hook it up in your regular signal chain using the normal input and output and then you can hook it up in the effects loop of the pedal to act as if it is a kill switch.



Controls: Threshold, Decay, 2-way Mode Switch
Connectors: Input, Output, Return, Send, 9V DC In, 9V DC Out
Current Draw: 20 mA (DC 9V)
Weight: 400 g (15 oz.)
Recommended AC Adaptor: PSA Series


This Boss pedal will limit the amount of noise you will have through your effects chain. This is for the guys who use a lot of distortion and possible some extra overdrive peals for high gain purposes. If you don't use high gain then you probably don't experience a lot of noise in your tone and signal chain. For those who do use a lot of gain and possibly some high output pickups would need something to tame all of that noise.If you play blues rock or a soft rock then you probably would never need a pedal like this.

I have found that a noise gate also helps when playing gigs in different places where they might not have good electrical outlets and you get some added noise. Possible the wiring is off and so extra noise is introduced into the line. A noise gate would help in that situation just to have in case you ever run into that problem.

This pedal can act like a kill switch. If you run all of your effect in the send and return of this pedal you can step on the foot pedal and shut off all the sound from your rig. You can also run it like its supposed to when it will shut down the noise form the rig. All you do is set the threshold and and decay to how much and how quickly it will shut off. You will need to switch that up as you see fit from room to room outlet to outlet.


At new you can find these pedals for right around $115, which isn't bad for this pedal. I would recommend everyone who regularly gigs to have one of these pedals because the noise from room to room will affect you rig each time and it can be needed if you have high gain in your tone.

VishNuRoXoUt's review"Great addition to a pedalboard!"

Boss NS-2 Noise Suppressor
The Boss NS-2 is a digital noise suppressor pedal designed to cut white/unwanted noise from you guitar signal. This particular noise suppressor has your standard Input and Output as well as an effects loop Send and Return. All of which are 1/4" jacks.


The Boss NS-2 is very easy to set up, and has a couple of ways to do so. The most effective ways being Guitar Signal into Input then Output into Amp, then have the noisy pedals (I use mine just for the dirt section.) in the effects loop of the NS-2. The other way is a little trickier. Guitar Signal to the INPUT of the NS-2, then the SEND of the NS-2 to the amp input. Then the effects loop SEND of the AMP into the effects RETURN of the NS-2, then the OUTPUT of the NS-2 into the effects RETURN of the AMP. This is called the 'X Configuration' or 'X pattern' and is effective for eliminating noise from the front of the amp and the amp itself. It works best for high gain amplifiers that get noisy when the gain is increased. Other than that the Threshold and Decay are set to taste. It's a fairly easy pedal to use. You just find a setting and leave it.


I've used the NS-2 for guitar and bass. It works well for both. It doesn't really change my sound too noticeably in a live setting, but there is a subtle change to your tone. The gate can cut your sound if you set the threshold too high, but it can be set to not effect your sustain if you set it up right.


For the money it's definitely a worthy pedal for any board. It does it's job and is very affordable. I've tried a few others and haven't found a real need to switch from my NS-2. I sold my original NS-2 and recently came back to it. It's a great pedal. Built like a tank, like most Boss pedals.

Heavyspender's review

Boss NS-2 Noise Suppressor
This is a straight noise suppressor with really only one purpose: and that's to suppress noise ! I believe it is digital. It cannot be edited via computer. This is a floor pedal, so it is not rackable. This unit has an input and an output for going from the guitar to the rest of your guitar pedal chain then to the amp. However, it also has additional send and return inputs and outputs, which essentially turns your pedal rig into an effects loop. This unit is definitely most effective when utilized in this way.


The general configuration/setup is simple. Sound/effects editing is easy. It's got two modes: one to mute your signal and the other is the actual noise reduction mode. It's got two knobs, threshold and decay. You need to tweak these two knobs to get the maximum, most effective noise reduction possible without compromising your tone and sustain, which the unit can do if you set the threshold too high. I bought this used, so I don't have a manual. However, I don't think it's necessary.


As said, this effect is for one thing and one thing alone. It is for noise suppression. It does what it does very well. It reduces hum, feedback, and other noise very well. I own a DOD Yngwie Malmsteen preamp overdrive pedal, and Yngwie himself will tell you that that little unit is noisy. When you put this pedal before the DOD in your chain, utilize the effects loop function. You can hear the wonderful sustain from the DOD without the annoying noise, as long as you don't set the threshold too high, thanks to the Boss Noise Suppressor.


I've been using this unit since the beginning of this year. I love it's noise suppressing capabilities. It's not the most glamorous pedal, but I feel it is an essential component of one's pedal chain. I don't know what I did before I bought this unit. The only thing I don't like about it is that it kills your sustain if you set your threshold too high. This is unfortunate, because the higher you can set your threshold, the better the noise suppressor effect. If you can be successful at finding a happy medium between these two factors, you will also be happy with the unit. I checked out rocktron's version, but nobody swears by their noise suppressors as much as people do with their Boss noise suppressor. The pedal is kind of pricey in my opinion, but since it is so essential to your rig, it is money well spent. I have no regrets about buying this unit. I needed it, plain and simple, and it does its job well.

MGR/Superdown Ritual's review"Boss Noise Suppressor NS-2"

Boss NS-2 Noise Suppressor
100$ at Sam Ash. Got it because I have a psychotic DOD pedal called Death Metal Pedal, its not the name it was the feedback and noise it gave while youre not playing it and when I put that psycho DOD with my precious and clean Boss V-Wah - not a good mix, like the two pedals arent made for each other -theyre not.

And I like the fact that the Noise Suppressor brings the DOD and the V-Wah together and eliminates all the size noise and feedback. Now I am actually able to put the DOD full volume without blood coming out of my ears. And also it acts as a power supply, so I bought a daisy chain for 15$ and hooked up my Zoom Drum machine, Zoom 606, DOD, V-Wah all together, so now I only have one adapter in the outlet and all of them are working, instead of unplugging and plugging 4 adapters into 2 outlets.

Dude, its a Boss, you have to love it. No you dont. Seriously, its a noise suppressor what wouldnt u like about a noise suppressor? It does its job, my case was extra hard, I dont think MXR Gate would do the job.

Its a Boss, ahem a Tank! And the quality is smart, the whole noise eliminating thing works great, for 100$ is kinda a lot, but if it will last me a life time, its golden.

If youre dealing with insane pedals, example: trying to have 2 low-end distortion pedals on at same time without getting a headache, its possible!

MGR/dj's review"Boss NS-2"

Boss NS-2 Noise Suppressor
Paid $35 through internet auction.

The unit is very easy to use, and very effective. It has a very useful decay knob that lets you control the gating action.
The gating is very smooth unlike traditional gates. I have owned rocktron rack pieces and I prefer the Boss NS-2.

I'm pleased with everything.

Like all Boss pedals, it is built like a tank. It should provide many years of reliable service.

If you need to quiet up a high gain rack or pedal board, you couldn't find a more effective, and reasonably priced unit than the NS-2.

sonofanzinedom's review (This content has been automatically translated from French)" Perfect for moderate noise"

Boss NS-2 Noise Suppressor
Noise gate pedal with exit and return loop to integrate noisy pedals.


Very simple no manual.
An input to an output loop pedals noisy (you can put the other after) a return loop pedals and noisy output to channel 1 or 2 of the amp.
I personally have put my fake wampler tape echo in the loop of the amp so after the noise gate, and my harmonize HarmonyMan at the beginning before the NS-2 for the direct detection of the clean guitar.


Perfect for up to half on guitar with two OD OD + one Disto


As I have long asked what pedal noise gate buy, between the BOSS NS-2 cheap, especially used, and the ISP Decimator (but in this case that the V1, V2, the Gold? ) I give you my opinion after buying the BOSS NS-2 and three days of testing, it can be used to indecisive.
So on my system behind Wampler Hotwired (double OD pedal and distortion) and CUSTOM SCREAMER home Techniguitare (OD) when I clicks OD and distortion hotwired the NS mode 2 Threshold reduction in third and Decay 0 it's perfect, no change in sound and zero noise!
Same thing with the OD OD Hotwired + custom screamer.
If I clicks all for the sound of death that kills (bodybuilder donf with harmonic everywhere) in the same position there is a small bit of noise you can hear when I stop playing, not really a problem for I think we should push the NS-2 to more than half (almost three quarters) to find the perfect silence. Here you listen carefully you may realize that you lose a little bite so acute in sound but really must compare / OFF to realize.
After I tried pushing the NS-2 background (Decay always zero) where we eat a little sharp, but you have to have the stuff that makes a lot of noise to get there.
So I would say that with the stuff pretty clean the NS-2 is just fine, no need to spend more.
I do not put 10 because in these entrenchments she eats some of his, but I was impressed with the cleaning action of this pedal MR Clean!
The only other noise gate I've used before is the one built into my Rocktron Chameleon (Hush old version) that was used to clean her after my machine Cream H & K tube preamp that was quite loud, it worked well too but version 2 OD pedal behind this distortion and MS-2 small price (used anyway) is a bargain.

gregours100's review (This content has been automatically translated from French)" Super Tool"

Boss NS-2 Noise Suppressor
Noise gate with a loop to put the noisy effects. Ability to power other pedals. All analog


Input from the tuner in the loop, I place a wah a compressor and a blues driver equa. Output to the effects on the bases or the time modulation. . Feeds other effects via a garland not supplied. Easy to use. I do not use the mute.


it works the thunder. The equa single facade breath like a herd of beef asthmatic. Placed in total silence loop. Do not color my sound as described in the notice before it is completely neutral.


Probably one of the most useful and functional I've ever bought pedals. Without it, my head jvm 410 feedback very quickly. With a dream. Just the little noise normal dun tube amp. The settings are very simple and adapt to his gear and his game
