Description
Introducing the Boss NS-2 Noise Suppressor, an innovative solution for eliminating unwanted noise and hum from your guitar or bass signal. Perfectly balancing technical precision and musical sensitivity, this effects pedal ensures that your original sound's tonality and natural attack are preserved.
Unlike typical noise gates, the NS-2 features Boss's unique noise detection circuitry that accurately separates the guitar sound and the noise components. This sophisticated technology allows the NS-2 to maintain your guitar's natural dynamics and tonality, resulting in a clean signal free of hum and hiss, but with your core tone fully intact.
The NS-2 provides flexible noise suppression controls. The threshold knob lets you adjust the sensitivity of the noise detection circuit, allowing you to dial in the perfect amount of noise reduction for your setup. The decay knob controls how quickly the NS-2 clamps down on the noise once your guitar signal fades.
Like all Boss pedals, the NS-2 is built for the road. Its robust metal chassis and footswitches are ready for any gig or studio session. Power it with a 9V battery or Boss's PSA power supply. With the Boss NS-2 Noise Suppressor Pedal, you can achieve pristine tone at any volume.
Key Features:
- Innovative noise suppression pedal for eliminating noise and hum in guitar and bass effects and amplifier setups
- Unique noise detection circuit preserves the natural attack and envelope of an instrument's sound
- Adjustable threshold and decay knobs for shaping the elimination/suppression as desired
- Road-ready construction with a rugged metal chassis and footswitches
- Powered by a 9V battery or Boss's PSA power supply
- Compact size to fit perfectly on your pedalboard

Owner Insights
We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Boss NS-2 Noise Suppressor.
Setup and maintenance
-
Using the 4-cable method isolates noisy pedals and the amp's preamp within the NS-2's loop, optimizing noise reduction in complex setups.
Source -
Configurations suggest placing only drive, compressor, and EQ pedals in the NS-2 loop for optimal noise reduction while keeping modulation effects outside the loop.
Source -
Adjust threshold to avoid cutting off quiet notes; set decay longer for sustained chords to maintain natural fade-out.
Source
Features and functionality
-
The NS-2 can effectively manage noise from single coil pickups and high-gain settings but may not eliminate buzz during play.
Source -
The NS-2's send/return loop improves tracking by using the dry guitar signal as the gate's trigger, enhancing noise suppression in high-gain, stacked pedal setups.
Source
User experience
-
Owners mention the NS-2 reduces noise without compromising the tonal quality of single coils, though some residual buzz may remain audible.
Source -
Owners report that using the NS-2 loop results in dramatically reduced hiss compared to placing it at the end of the signal chain.
Source -
A common setup involves having the NS-2 first in the chain, with other noisy pedals in the loop, effectively silencing the chain when not playing.
Source -
Users report needing to experiment with threshold and decay settings to find the balance between noise cancellation and sustaining tone.

A must have
Completely remove that "hum" from your sound when your idle. Once you know how to dial it in, you're stage sound will not be interrupted.

Great
Keeps out all the noise, always on for me! I run the 4 cable method, running my guitar into the input, then through the send into my gain and chorus pedals then into the front of my amp. Then I use the fx loop of my amp into the return of the pedal and use the output into my delay and other post fx pedals.
Preferred Settings + Usage:
Reduction Mode, Threshold: Max, Decay: 9 o’clock
Best Gate for the price, but not the best in general
I got this for 40€ (50$?) and it is nice to have it for my drive/distortion section. It does it's job, I'm just not that glad with the settings in reduction mode now, but I only tested it at home and not in the rehearsal room with my bigger amps, maybe I'll find some good settings there after lockdown. It seems as if i had to decide between proper reduction and enough sustain, so that's something i need to figure out. The mute mode is working fine and hey, for that price it is still pretty good.
Preferred Settings + Usage:
Guitar -> NS-2->BB-2->DS-1->ST-2->CH-1->EH-1->RF-1->TU3-> Amp

A huge impact from a small device!
I got this to solve the chaos or cacophony which arises on my live rig once the DRIVE pedal is engaged. I used to have another gate pedal but had never needed another until the last several shows so I picked up the NS-2 and holy hole in a donut, Batman, this has very minimal coloration on my tone and cuts the noise. It is one of those things you may not wish to acquire but is utilitarian so it is needed.

One of the best
NS-2 is one of the best noise gate/noise suppressor (ng/ns) pedals every designed. The threshold and decay controls let you customize the sound for any amp volume level and/or amp gain level. Built-in loop works well to help isolate and control noisy pedals or use NS-2 in four-cable method/X-pattern wiring. Pedal is designed to supply power to other Boss pedals. Great pedal that's easy to use and very effective.

The best At The noise Gate
If you’re absolutely in love with white noise ambience you should avoid this noise gate. For all fans of less minimalist noise should put this into every rig. This one does the job flawlessly especially in 4-cable-setting with an effects send/return-circuit. And as with all the other Boss-pedals, you can jump from a building with this one and best bet: this thing will survive. Anyway… don’t jump!

The one and only...
I tried a few different Noise Suppressors in the last 5 or 6 years. I also worked with a lot of different artists, live and inside studios. I had 3 or 4 pedals during that time and I need to say that all of them works almost the same way, but the NS-2 is my choice. It's not the easiest to use, like the Decimator which has only one knob (the knob is very sensitive, thou). However, if you dedicate your time to learn how to get the best sound out of your board, you will understand why there are so many people using the NS-2. First of all, connect it the way it's made to be connected: Guitar > NS-2 > SEND to Compressor/OverDrive/Distortion/Fuzz/Booster/any other "noisy pedal" that you have > RETURN to NS-2 > Delay/Reverb > AMP. Secondly, dial the knobs in order to make it fit your need. It's totally different if you play modern metal than if you play blues or indie-rock. I use the Threshold around 3 o'clock and the decay around 9 o'clock (almost facing each other). I like how it does not cut the sound abruptly. My advice: grab the NS-2 and give it a try.

Does what it does, and does it well.
Is it the cheapest? Nope. Is it the best? Depends on what you are looking for. But there is no question that when it comes to getting rid of the hiss and other non-musical stuff coming out of your effects chain, the NS-2 is the standard. It is what everything else is compared to. Lots of options make it very adaptable to a wide variety of configurations. It's not glamorous or sexy, but when you need to tame a massively overdriven distorted effects chain, it'll just work.
