A Benchmark for Taming High-Gain Setups
When stacking distortions, overdrives, fuzz, compressors, or saturated preamps, background noise quickly rises: hiss, hum, interference... The Boss NS-2 is a classic on modern pedalboards, featuring a detection circuit designed to reduce noise without degrading the playing feel. It naturally fits both in front of the amp or within a more complex chain, where a too aggressive noise gate would cut notes and kill sustain.
Who Is It For?
The NS-2 is ideal for guitarists (from beginners to advanced) who want a clean sound in rehearsal, studio, or live settings. It excels in rock, hard rock, metal, punk, and any context where a lot of gain or compression is used. If you play with a pick and sharp attacks, or if you alternate palm-mutes and clean silences, it helps achieve a more precise and professional sound without sacrificing dynamics.
Settings, Modes, and Pedalboard Integration
The THRESHOLD knob sets the level at which the pedal activates: the higher you set it, the more pronounced the noise cut. The DECAY adjusts the release speed to avoid "pumping" effects and maintain a natural note decay. The MODE switch offers two behaviors: MUTE for very clean silences, and REDUCTION for a more gradual and natural noise reduction. Regarding power, it is compatible with Boss PSA230 and Korg KA189 adapters and features an additional 9V female output for the Boss PCS20 multi-pedal power cable option.
Sound Character
The NS-2 stands out with a discreet and musical action: it cleans background noise without muffling the attack or smoothing out expression. Properly set, it preserves the "direct" feel under the fingers, lets sustain breathe, and respects playing nuances (light attack, palm-mute, vibrato). The result: a cleaner sound, sharper note cuts, and better clarity, especially with generous saturation.

A simple and effective noise suppressor. Not very pretty, but hey, it\'s a utility pedal that I always leave on (in\ "mute\” mode and the pedal off, it works in reduction mode. I use it in the 4-cable method, because that way it cuts off the noise of the pre-amp pedals (overdrive and distortion), but also the amp preamp (mesa mini rectifier that sends into the saturated channel) and the effects in the loop.
So we tell ourselves that it is curious to spend 100 bucks on a pedal that\ "does nothing\”, but once you have it, you can't do without it because it\'s the silence when you stop playingAutomatically translated

No more the eternal turbo-diesel in the background.
My settings:
-Decay: 1/3.
-Threshold: 2/3.
-Pedal always on.
And I don't touch anything anymore!
Gear:
-Multi-effects platform or analog pedal chain.
-Amp: Fender/Gretsch/Marshall.
-Guitars: Fender/Gibson.
Does it color the sound? As far as I know the sound of an electric guitar is always colorful, adjust your effects!
I wonder why I didn't buy this sooner, especially considering the price...
Simple, effective, you forget it and it does its job... ESSENTIAL!!!Automatically translated

My latest purchase to replace my Hush II CX which passed away. This wired loop pedal in my multi-effects is simply extraordinary. And it's much better than my old HUSH. I recommend everyone to use this pedal especially if you have a large chain of effects. Fast delivery, short quality service as usual. Thank you Woobrass!

Absolutely essential pedal for me who uses a Fender Deluxe Hot Rod III, all-tube amp and preamp, so already quite a bit of breath at high power, as well as a pedalboard that also generates quite a lot!
This Boss Ns 2 connected in a loop removed all extraneous noise, so great for me!Automatically translated

Questions frequently asked
Is the Boss NS-2 suitable for a high-gain pedalboard?
Its detection circuit reduces hiss and noise generated by stacking distortion, fuzz, compressors, or saturated preamps. It helps preserve attack and sustain when the gain is high.
What is the difference between the MUTE and REDUCTION modes?
The MUTE mode provides very clean silences. The REDUCTION mode acts more progressively to maintain a natural note decay.
How to adjust the Threshold and Decay?
The THRESHOLD knob sets the noise reduction trigger level: a higher setting increases the cut. The DECAY control adjusts the release speed. It helps avoid pumping effects and preserves sustain.
Can it be powered with a Boss PSA230 adapter?
This pedal is compatible with Boss PSA230 and Korg KA189 adapters. Its current draw is 20 mA and a 9 V female jack allows using a Boss PCS20 daisy chain cable.
Does the NS-2 cut notes played with palm mute?
A proper DECAY setting preserves the natural decay of notes while clarifying stops and palm mutes.
