There’s a moment every guitarist knows well. You’ve finally dialed in that perfect high-gain tone. The distortion is thick and saturated, the sustain rings for days, and every note feels powerful. But then, you stop playing. Instead of glorious silence, you’re met with a torrential downpour of hiss, hum, and feedback. It’s the sonic equivalent of static on a vintage TV, and it completely undermines the professional sound you’re striving for. For years, I struggled with this exact problem, especially when stacking overdrive pedals or using single-coil pickups with a cranked tube amp. This unwanted noise isn’t just an annoyance for bedroom practice; in a studio mix or a live performance, it can be a deal-breaker, muddying the clarity between phrases and creating a wall of distracting buzz. The search for a solution that kills the noise without killing your tone is a true quest, and it’s what led us to extensively test one of the industry’s most enduring solutions: the BOSS NS-2 Noise Suppressor Pedal.

What to Consider Before Buying a Noise Suppressor Pedal
A noise suppressor pedal is more than just a piece of gear; it’s a key solution for achieving professional-grade clarity and control over your sound. Its primary function is to eliminate the ubiquitous 60-cycle hum from single-coil pickups, the high-pitched hiss from cascaded gain stages (like stacking multiple distortion pedals), and the unruly feedback that occurs at high volumes. The main benefit is pristine silence when you’re not playing, which allows the notes you *do* play to have more impact and definition. This is crucial in recording environments where a clean signal is paramount, and equally important on stage where it prevents embarrassing noise from blasting through the PA system between songs. It tightens up chunky, percussive metal riffs and cleans up delicate, nuanced passages, making your entire performance sound more polished and deliberate.
The ideal customer for a noise suppressor is any guitarist or bassist who uses significant amounts of gain, whether from pedals or an amplifier’s distortion channel. This includes metal players, hard rockers, and even blues guitarists who use single-coil pickups and like to push their amps into overdrive. It’s also an essential tool for anyone with a complex pedalboard, as each additional pedal and cable adds a little more noise to the chain. Conversely, a player who primarily uses clean tones with minimal effects might not find a noise suppressor necessary. If your rig is already dead-quiet, adding one could be redundant. In that case, your budget might be better allocated to other effects that shape your tone, rather than clean it up.
Before investing, consider these crucial points in detail:
- Tone Preservation & Transparency: The single most important job of a noise suppressor, after quieting your signal, is to get out of the way when you’re playing. A poor-quality gate can suck the life out of your tone, cutting off the natural decay of your notes and altering your guitar’s attack. Look for pedals known for their transparency, ensuring that your core sound remains intact. The BOSS NS-2, for instance, uses a unique noise detection circuit specifically designed to preserve the instrument’s natural envelope.
- Controls & Flexibility: At a minimum, a noise gate needs a “Threshold” control, which sets the volume level at which the gate opens and closes. More advanced pedals, like the NS-2, also include a “Decay” or “Release” knob. This determines how quickly the gate closes after your signal drops below the threshold, allowing you to fine-tune the effect from a hard, choppy gate to a smooth, gentle fade. This flexibility is key to making the pedal work for different playing styles.
- Routing Options (The Send/Return Loop): This is a game-changer and a feature that separates basic noise gates from professional tools. A pedal with a send/return loop allows you to isolate your “noisy” pedals (distortions, overdrives, compressors) within the gate’s detection circuit, while leaving your time-based effects (delay, reverb) outside of it. This prevents the gate from unnaturally cutting off your delay tails or reverb trails, a common problem with simpler setups. As we’ll discuss, mastering this feature is the key to unlocking the full potential of the BOSS NS-2 Noise Suppressor Pedal.
- Build Quality & Durability: A pedal is meant to be stomped on. Look for a robust metal chassis that can withstand the rigors of gigging. BOSS pedals are legendary for their tank-like construction, and this is a critical consideration for any gear that will live on your pedalboard. A reliable footswitch and sturdy knobs ensure the pedal will be a long-term investment, not a temporary fix.
Choosing the right noise suppressor can elevate your entire rig from sounding amateurish to sounding studio-ready. It’s an investment in silence, clarity, and professionalism.

First Impressions: The Industry Standard in a Box
Unboxing the BOSS NS-2 Noise Suppressor Pedal feels like greeting an old friend. The iconic compact pedal design—sturdy, off-white metal casing, reassuringly solid footswitch, and simple control layout—is instantly familiar to anyone who has been around guitars for more than a week. There’s no fluff here; inside the box, you get the pedal, a 9V battery to get you started, and the user manual. Weighing in at 522 grams, it has a substantial heft that speaks to its durability. It feels like it could survive being run over by the tour bus, a reputation BOSS has earned over decades.
Setting it on our board, its standard 6″ x 3.8″ x 2.7″ dimensions mean it fits comfortably alongside other standard-sized pedals. The controls consist of just three knobs: Threshold, Decay, and a Mode selector (Mute or Reduction). The layout is intuitive and uncluttered. The Threshold knob determines the level at which the noise suppression kicks in, while the Decay knob dictates how quickly the gate closes. The Mode switch is a clever addition, allowing the pedal to function either as a traditional noise gate (Reduction mode) or as a handy mute switch for silent tuning or guitar changes (Mute mode). Our initial impression is one of rugged simplicity and purpose-built design. It’s not flashy, but it’s built for a very specific, crucial job, a quality that is immediately apparent before you even plug it in. Its feature set is focused and effective, promising to solve a problem without creating new ones.

Performance Deep Dive: Silence Without Sacrifice
A noise suppressor lives and dies by its transparency and effectiveness. It has to perform a delicate balancing act: ruthlessly eliminate unwanted noise while remaining completely invisible to the ear when you are playing. This is where many lesser pedals fail, either letting too much hiss through or aggressively chopping off the tail end of your notes. Over weeks of rigorous testing in both studio and live practice settings, we pushed the BOSS NS-2 Noise Suppressor Pedal to its limits with a variety of guitars and amps, from a vintage Stratocaster with noisy single-coils to a modern high-gain setup with active pickups. Our findings reveal why this pedal has remained an industry staple for decades.
The Heart of the Silence: The Unique Noise Detection Circuit
The magic of the BOSS NS-2 Noise Suppressor Pedal isn’t just that it gates your signal; it’s *how* it gates your signal. At its core is a unique noise detection circuit that separates the guitar’s signal from the noise floor. Unlike simple noise gates that just slam shut when the volume drops, the NS-2 analyzes the entire frequency spectrum. It intelligently identifies the hum and hiss without clamping down on the harmonic content of your actual guitar tone. In practice, this translated to a remarkably natural playing experience. When we stopped playing a heavy, distorted riff, the silence was absolute and immediate. There was no lingering hiss or hum. Yet, when we let a note ring out and sustain, the decay was smooth and organic. The pedal didn’t prematurely choke the note; it allowed it to fade out naturally before engaging the gate.
This was confirmed by numerous users, with one noting it delivered “total silence AND all my tone.” We found this to be precisely the case. With a Fender Stratocaster plugged into a cranked Marshall JCM800—a classic recipe for 60-cycle hum—the NS-2 completely tamed the buzz between phrases without thinning out the iconic Strat “quack.” The Threshold and Decay knobs are the key to this fine-tuning. We started with both at zero, as one user recommended, and were astonished at how effective it was even at this minimal setting. For more aggressive high-gain tones using a BOSS ML-2 Metal Core pedal, we had to push the Threshold up to around 1 o’clock. This is where the Decay knob becomes your best friend. By adjusting it carefully, we could achieve a super-tight, staccato gate effect perfect for modern metal, or a slower, more “tape-like” fade for classic rock leads. The pedal’s ability to preserve the crucial attack and envelope of the sound is its standout feature, making you forget it’s even in the chain until you turn it off and the floodgates of noise reopen.
The “X-Method” Unlocked: Mastering the Send/Return Loop
If there is one piece of non-negotiable advice for any owner of this pedal, it’s this: you must use the send/return loop. Several user reviews emphasize this point, calling it the “CORRECT WAY” to use the pedal, and our testing confirms this is not an exaggeration. Simply placing the NS-2 at the beginning or end of your effects chain is a mistake; it will work, but you will not experience its true power. The four jacks (Input, Output, Send, Return) are there for a reason, enabling what is often called the “4-cable method” or “X-method.”
Here’s how we set it up for maximum impact:
1. Guitar -> NS-2 Input
2. NS-2 Send -> Input of Noisy Pedals (e.g., overdrive, distortion, compressor, wah)
3. Output of Noisy Pedals -> NS-2 Return
4. NS-2 Output -> Input of Modulation/Time-Based Pedals (e.g., chorus, delay, reverb) -> Amp Input
This configuration is ingenious. The NS-2’s detection circuit uses the clean signal coming directly from your guitar at the “Input” jack to decide when to open and close the gate. However, the actual noise reduction is applied to whatever is running through its send/return loop—your gain pedals. This means the gate’s behavior is dictated by your clean, dynamic playing, not the compressed, noisy signal coming out of your distortion pedals. The result is flawless tracking. The gate opens instantly when you pick a string and closes smoothly when you mute, because it’s listening to the pure guitar signal. Furthermore, because your delays and reverbs are placed *after* the NS-2’s output, their beautiful, ambient trails are not cut off when the gate closes. We tested this with a long, shimmering reverb, and the pedal perfectly silenced the distortion hiss while allowing the reverb tail to decay naturally. Mastering this setup, which unlocks its full professional potential, is the difference between having a good noise gate and having a truly silent, professional-sounding rig.
On the Board and On the Road: Build Quality and Usability
The practical aspects of a pedal are just as important as its sonic performance. The BOSS NS-2 Noise Suppressor Pedal is, unsurprisingly, built like a fortress. The metal chassis feels indestructible, the knobs have a firm, responsive turn, and the footswitch provides a satisfying click with no wiggle or fragility. This is a pedal designed to be stomped on night after night for decades. We found this sentiment echoed by users who praise its sturdiness and suitability for both studio and live use. It’s a true “set and forget” piece of equipment; once you dial in your settings, you can trust it to perform consistently every time you power up your board.
Beyond its toughness, the NS-2 offers great utility. In “Reduction” mode, the red LED indicator lights up only when the gate is actively suppressing noise, giving you useful visual feedback. Switching to “Mute” mode transforms the pedal into a killswitch, silencing your entire output signal. This is incredibly useful for tuning silently on a loud stage or for switching guitars without causing loud pops through the sound system. It’s a simple feature, but one that demonstrates BOSS’s thoughtful design, catering to the real-world needs of gigging musicians. We also appreciated its ability to power other BOSS pedals (via an optional PCS-20A daisy-chain cable), helping to simplify power management on a crowded board. From its straightforward operation to its rock-solid reliability, every aspect of the NS-2 is designed for the working musician. It’s an investment that pays dividends in both sound quality and peace of mind.
What Other Users Are Saying
Across the board, user feedback for the BOSS NS-2 Noise Suppressor Pedal is overwhelmingly positive, with a common theme emerging: its effectiveness is directly tied to using it correctly. Many seasoned users share detailed instructions on the 4-cable method, with one stating plainly, “Perfect pedal for cutting the noise IF USED CORRECTLY.” This sentiment is echoed by another who calls it the “best guitar rig investment I’ve made yet,” specifically after taking the time to integrate it properly into their amp’s effects loop, achieving “total silence AND all my tone” even with a high-gain amp and single-coil pickups.
This highlights the pedal’s professional-grade capability. The praise isn’t just about killing noise, but about doing so transparently. Reviewers frequently mention how it “will kill all this annoying noises that screw your mix” in a studio context and keeps their entire rig “dead silent” for live performance. The sheer joy and relief are palpable in comments like, “The noise is finally gone thank you!!” and how it “makes you feel like a sheer joy while playing.” There is very little in the way of negative feedback, with the primary “con” being more of a user-education issue—those who initially use it as a simple two-jack pedal are often underwhelmed until they discover the power of the send/return loop. This collective experience confirms our findings that a little setup knowledge transforms this good pedal into an indispensable one.
Other Essential Pedals to Consider
While the BOSS NS-2 Noise Suppressor Pedal is a master of subtraction—removing unwanted noise—many guitarists are also looking to add character and dimension to their sound. If you’ve tamed your rig’s hiss and hum, you might be exploring other effects in a similar price bracket to round out your pedalboard. Here are three excellent alternatives that, while serving different purposes, represent fantastic value and are beloved by musicians.
