This is a Boss product, which means you are getting a high quality stompbox that is worth every penny. You also have great customer service, and an item which will always hold a high resale value. I have owned TONS of Boss pedals and never disliked any of them. They have always performed up to my expectations. Now for the NS-2. This is my 2nd one to own and let me tell you, this is an ultimate problem solver. If you have a noisy effects loop, this pedal is equipped to clean that right up. If you need something to mute your signal with the stomp of a foot, this is it. If you are having a lot of noise problems, this is it. Loads of big names use this pedal, one in particular that has always come to my mind is Hatebreed, a band that relies on massive amounts of gain that would probably otherwise be a screaming mess in between breaks in the guitar riffs. But I've seen them, I've seen tons of bands using this pedal and none of them have had noise issues live. The NS-2 is my last line of defense in my chain. I have a noise gate on my processor, then I go to my rack gear, then the NS-2, then amp. I used to have problems with feedback, especially in small venues and would have to crank the noise gate out on my processor thus killing my tone, sustain, and just destroying my sound. I tried the Decimator by ISP but same problem, constantly having to re-adjust and dime it out and kill my tone. Now the noise gate on my processor is set LOW and the NS-2 is set with the threshold at a little over mid way and the decay control set at about 3 quarters, for a more natural "fade out" effect when I stop playing. That way you don't have an abrupt stop in your sound. You can also switch the pedal over to a MUTE feature so that you can mute your signal. I have no use for this as I have a volume pedal, but its a good extra feature. This pedal stays on at all times whenever I'm playing and is mounted in a shelf in my rack. Set it and forget it. No issues with tone destruction, and the good thing is, you can even turn it off whenever you want if you are worried about it holding back your signal. It has cleaned up my sound. Breaks have become completely silent, and I have no more amp noise, just the hum of the fan in my amp head is all I can hear. This pedal is a life saver, especially if you have a lot of gear junking up your signal. Its not going to fix electrical problems or anything like that! A lot of rookie guitarists don't understand that some noise isn't their rig at all but their power. Use the right adapters, good cords, and GET A POWER CONDITIONER and you will be just fine. Add the NS-2 to your rig and noise is dead. Period.

I have a Marshall dsl20 amp that I’ve struggled with a lot of hum when using. It’s dead silent when you turn the volume on the guitar down so I know it’s not the amp. It’s likely bad power and just the natural side effect of high gain. Everything in my signal chain is of good quality so I’m not sure what I can do to quiet the noise. So I decided to pull the trigger on a gate. The boss ns-2 had good reviews and the price was right. This things a game changer. I first added it to my pedal board and plugged it straight into the the front of the amp as the last pedal in the chain. This worked good but I had to turn the threshold to the max to get rid of the noise. So today I finally used the effects loop on my amp and have the threshold at about 3/4 now. This seems to work better if you have the option on your amp. I am pleased with these results for about 100$. When I sit idol the guitar is quiet enough that it often startles me as I play the first note as I was used to a loud hum with high volume. I hope this helps anyone that is having hum problems. I’ll never play this amp without it again. Buy buy buy!

Does exactly what it’s supposed to do! Played at high volume last Saturday at the Superdome. No feedback, no noise!

I had a bit of a hum coming from my rack because I use distortion pedals with high gain. I was listening to a recording of my band and in one song where the guitar was quiet, I could hear the hum of my pedals over the band. That made me conscious of it, so I started to make sure I was kicking the pedal off during those parts. I had avoided a noise suppressor pedal as I was concerned about dampening my sound and tone. I started looking at pedals and figured with Amazon's return policy, I could always return it if I didn't like it. This pedal was one the more economical choices with good reviews and since it was a Boss I figured I had nothing to lose. When I received the pedal and plugged into my rack, problem immediately solved. It didn't take a lot of manipulation of the controls either. My tone and volume were unaffected, but the hum was gone. If you're looking to get rid of the nasty pedal board hum, look no further.

works great....but is a noise gate really needed? i put this noise gate in front of my 2 drive pedals but turns out i could silence the pedal noise by placing a finger on most of the strings after strumming and the decay/trails dies down. i replaced this 9v plug and pedal space with a Keeley compressor plus.

I have to say, I was a bit skeptical about this. It's tough for a guitarist to spend $80+ on a pedal that ELIMINATES sound, rather than amplifies it. But once you get over that psychological hurdle, this pedal kicks some serious ass. I play a Schecter PT Custom and a Fender American strat through a Fender frontman amp, and use an effects set-up with a variety of different dirty pedals (Big Muff, MXR custom badass overdrive) and I was getting some crazy feedback/hum when I'd stop playing, especially with the strat (single coils will do that to you). When I was on my amp's dirty channel and then hit my boost pedal for a solo, for example, the excess noise was unbearable. Same when I kicked on the Big Muff. This pedal solves those problems quite well. There is absolutely NO lag time - it turns off as soon as you hit the first note. I encourage you to mess with the decay and threshold settings and find the best for you. For me personally, I've got the threshold at about 1 o'clock and the decay at about 2 o'clock, and I love the way it works. Some will argue that it sucks tone; it may cut your tone a TINY bit, to the point that it's barely noticeable. But that's the beauty of this pedal... when you're at high volume playing with the band, you can turn it off. I only use mine during quieter parts of songs, or in between tunes when I don't want to tick off my bandmates with hum and feedback from my rig. If you're frustrated by the noise from your amp or effects chain, BUY THIS PEDAL.
