The Boss NS-2 Noise Suppressor Pedal effectively eliminates noise and hum from the input signal while preserving the original sound's tonality. Natural attack and envelope remain unaffected by suppression of the noise components.
[This](http://www.premierguitar.com/articles/21355-rig-rundown-helmets-page-hamilton) rig rundown states that "Hamilton runs all of his pedals in front of the amp and controls the rig with a Custom Audio Electronics RS-5 MIDI Foot Controller designed by Bob Bradshaw. The signal starts with a Hello Kitty-modified Fryette Valvulator before going into an MXR Custom Audio Electronics Boost/Overdrive. From there the signal hits a Real McCoy Custom wah, Eventide TimeFactor, MXR Bass Octave, Boss PS-5 Super Shifter, Boss NS-2 Noise Gate…"more
Brad Clifford assembled a pedalboard for Rosamilia that uses two Loop-Master pedal switching devices to keep the sound pristine. The signal starts with the guitar running into an Ernie Ball VP JR volume pedal, and its tuner out hits a TC Electronic PolyTune Mini Noir. From there, the signal enters the first Loop-Master, which is connected to six pedals: a Boss NS-2. Described here, in this [Premier Guitar article](http://www.premierguitar.com/articles/21588-rig-rundown-the-gaslight-anthem).more
“It really cleans up your tone a lot without taking out too much sound from it. A typical gate works a little differently, but the Suppressor just cleans up the hum. When you have a really good, high-quality amplifier, I don’t think you really need a gate, but having something that helps take out some of the hum and the hiss of the electricity that’s going through the amp – especially when you’re travelling a lot to different countries with different electricity – helps a lot.”more
"The sixth pedal is a Noise Gate. With all that power on stage: House sound, monitors, backline, lights... you're bound to get a buzz. When there's enough time to track the buzz down and kill it, it's great, but there are times when there just isn't enough time to do that. This pedal is great for that. I can set a threshold so that sound is only let through when I play above a certain volume. This minimizes noise. The pedal also acts as a mute which allows me to tune the bass without being heard. It's a very cool pedal."more
"I don't have anything other than a Boss NS-2 noise suppressor pedal. I used that and then I go right into the Triple Rectifier. I have the gain up all the way, and I just use the clean and dirty channels. That's it. I only switch during one song, "Charlotte." For the most part, it's just full-on metal the whole time."more
"Enter the RG-16. This midi interface has made my life a lot easier. Now if I want to go from, say, my lead channel with my NS-2 and TS-9 to my clean channel with my compressor, DD7, RV5, on and my NS-2 and TS-9 off, I just have to hit one button on my Mastermind Midi Controller. It makes my life a LOT easier and makes tone changes a breeze. The setup was pretty complex and required the building of a ton of custom cables. The cable making was easy though, thanks to the custom cable making kits that Planet Waves makes. "more
At 5:11 of this Gear Interview video provided by Thomann Music, Unearth guitarist Ken Susi is asked about what 3 pedals he would use. "That's the easiest question anyone could ever ask me. 1. Boss NS-2 Gate 2. Maxon OD-808 3. Probably be a tuner because I'm a sh^&head. I constantly go out of tune because I thrash everywhere."more
0:10 - Syu can be seen in the studio with Galneryus, using an MXR Carbon Copy analog delay, a Vox V846 wah, a Boss LS-2 Line Selector, a Boss NS-2 Noise Suppressor, a Boss tuner and a BB King preamp pedal. This video footage was taken at September 10th, 2010 at an MIT Studio in Tokyo, Japan.more
Does what it does, but there are more accurate, better ones out there. The price and the effects loop, along with the DC out ability are the main advantages of this pedal.
If you don't have the experience, time or patience to dial in the right gate for your sound then I'd recommend an ISP Decimator or Decimator 2. Especially if you're a metal head.
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.
this does the job if noise is getting out of hand and you can't trace it. In many cases the solution is better supply management and I have taken this off my board recently but always on hand if I need it again
I didn't have this pedal for long before selling it.
As a gate itself, it worked great and did it's job just fine but I found this pedal to be a real tone sucker as I noticed cutting of a considerable amount of high end off my tone and turning my guitar tone to mud in a full mix, which is a deal breaker for me. I'm not saying it's an inherently bad pedal, this was just my experience with it.
So I personally wouldn't recommend but it might just be what works for you
My pedalboard uses multiple channels, that creates a lot of line noise. I run one of these on each channel with distortion, and soon as I stop playing, it cuts the noise. Great design!
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.
The loop-based design is a great way to really make it work no matter how much noise your loop produces, even if the idle noise is as loud as when you're not playing at all. It's very responsive, only a very very slight attack/decay that's not noticeable 99% of the time.
