Smoother and "More Natural" Than Your Regular Noise Gate!

The NS-2 effectively eliminates noise and hum of the input signal while preserving the original sound's tonality. The natural attack and envelope are unaffected thanks to the NS-2's unique noise detection circuit that precisely separates the guitar sound and the noise components.

BOSS NS-2 Features:
  • Compact 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
  • Threshold and decay knobs allow for shaping the elimination/suppression as desired

At Sweetwater, "Demo" usually means one of the following:

  • It spent some time on display in our store.
  • It was used in a sales training presentation.
  • It was returned by another customer who tried it out for a few days.

Every demo item we sell is certified to be in perfect working order and backed by Sweetwater's 2-year Total Confidence Coverage warranty.

Noise Suppressor quiet!

This Boss NS-2 pedal has totally eliminated any feedback sound from my guitar. Before that, I had a slight, but noticeable hum going on but now - no more!
Music background: guitarist


This is pretty awesome! It cuts out all the little noises I get through my guitars and amp. It works better than what I expected; for sure!
Music background: I've been playing guitar for about 40 years.


Works great. Doesn't suck tone.

Sweetwater Advice

Chris McCown

Kill the noise! Whether you're playing a Strat and dealing with the fabled 60Hz hum, or playing a guitar with humbuckers through a high-gain amp, you can seriously reduce or even eliminate the annoying interference you hear when you're not playing with this simple-to-use pedal. Why would you want to be heard if you're not playing? Just plug this into your effects chain before any reverbs or delays, and let the gate do the rest!
