What is the BOSS NS-2?
The BOSS NS-2 Noise Suppressor is a legendary pedal, widely recognized as the industry standard for eliminating unwanted noise from guitar, bass, and other instrument signals․ It’s a compact, stompbox-style unit designed to cleanly remove hum, buzz, and hiss without audibly affecting your desired tone․
As detailed in the NS-2 Owners Manual (PDF) available in multiple languages – including English, German, French, and Italian – the pedal operates by intelligently detecting the difference between your instrument’s signal and background noise․ It then actively reduces the noise floor, resulting in a clearer, more defined sound․
Unlike simple gate effects that can abruptly cut off sustain, the NS-2 utilizes a sophisticated circuit to provide smooth and natural noise reduction․ The instructions emphasize its ability to work effectively with high-gain setups and in studio recording environments․ It’s a tool for achieving professional-quality sound, as evidenced by its enduring popularity and continued use by musicians worldwide․
Why Use a Noise Suppressor?
Unwanted noise – hum, buzz, hiss – can significantly degrade your instrument’s signal, obscuring its clarity and impacting performance quality․ A noise suppressor, like the BOSS NS-2, addresses this issue by selectively reducing noise without compromising the core tone․ This is crucial for achieving a professional sound, both live and in the studio․
The NS-2 manual highlights scenarios where a noise suppressor is particularly beneficial: high-gain amplifiers, effects pedals that introduce noise, and single-coil pickups prone to hum․ It allows for a cleaner signal path, enabling greater dynamic range and more articulate playing․
Furthermore, the instructions detail how the NS-2 can improve recording quality by minimizing noise during tracking․ By reducing background interference, it simplifies mixing and mastering processes․ Ultimately, a noise suppressor isn’t about eliminating all sound; it’s about enhancing the signal-to-noise ratio, resulting in a more polished and professional audio experience․
Understanding the NS-2’s Controls
The BOSS NS-2 features a Threshold knob to set the gate, a Release knob for adjusting gate response, and a Noise Reduction Level indicator for visual feedback․
Threshold Knob: Setting the Gate
The Threshold knob on the BOSS NS-2 is the primary control for determining when the noise suppression circuit engages․ Essentially, it sets the “gate” – the level below which the pedal actively reduces noise․ Turning the Threshold knob clockwise raises the gate, meaning only signals above that level will pass through unaffected․
This is crucial for eliminating low-level noise like hum or hiss without cutting off the sustain of your notes․ Start with the Threshold knob fully counterclockwise and slowly increase it until the noise disappears․ Be careful not to raise it too high, as this will prematurely cut off your signal, especially with quieter playing styles or instruments․

The manual emphasizes finding the sweet spot where noise is suppressed, but your instrument’s natural dynamics are preserved․ Experimentation is key; different guitars, pickups, and playing techniques will require different Threshold settings․ The Noise Reduction Level indicator will assist in visually confirming the effect of your adjustments․
Release Knob: Adjusting Gate Response
The Release knob on the BOSS NS-2 controls how quickly the noise suppression circuit disengages after the signal drops below the set Threshold․ A shorter release time means the gate closes rapidly, potentially sounding abrupt or choppy, especially with sustained notes․ Conversely, a longer release time allows the gate to remain open for a brief period, creating a smoother, more natural fade-out․
The manual suggests starting with a moderate Release setting and adjusting it to suit your playing style and the characteristics of your instrument․ For percussive playing, a faster release might be preferable․ For instruments with long sustain, a slower release will prevent unwanted signal cut-off․
Finding the right balance is essential․ Too short, and the effect is noticeable and unnatural; too long, and the noise suppression becomes less effective․ Careful adjustment of the Release knob, in conjunction with the Threshold, is key to achieving transparent noise reduction․
Noise Reduction Level Indicator

The NS-2’s Noise Reduction Level Indicator, a crucial visual guide detailed in the manual, displays the amount of noise reduction being applied․ This isn’t a gain level indicator, but rather a representation of how aggressively the noise suppressor is working to eliminate unwanted sounds․
When the indicator illuminates, it signifies that the NS-2 is actively reducing noise․ The brighter the illumination, the greater the noise reduction․ Observing this indicator while adjusting the Threshold and Release knobs is vital for optimal settings․

It’s important to note that the indicator doesn’t necessarily equate to “better” noise reduction․ Excessive noise reduction can negatively impact your signal․ The goal is to find a setting where the indicator lights consistently during pauses, but remains largely unlit during playing, ensuring a clean and natural sound․
Connecting the NS-2
The BOSS NS-2 features standard ¼ inch input and output jacks, alongside unique SEND and RETURN connections, as outlined in the instruction manual․
Proper cabling ensures optimal noise suppression and signal integrity for a pristine audio experience․

It’s crucial to use high-quality cables for both input and output connections to maintain signal clarity and prevent the introduction of additional noise․ The instruction manual emphasizes the importance of secure connections for optimal performance․ Always double-check that the cables are firmly plugged into the jacks to avoid intermittent signal issues․
Using the Send and Return Jacks
The BOSS NS-2 distinguishes itself with dedicated Send and Return jacks, offering a more refined noise suppression experience․ The Send jack routes your signal before noise suppression to the Return jack, which then processes it․ This allows the NS-2 to analyze the pure instrument signal, improving its ability to differentiate between your intended sound and unwanted noise․
Connecting your instrument directly to the Input jack and then from the Output jack to your amplifier bypasses the Send/Return functionality․ However, utilizing these jacks is recommended, especially with high-gain setups․ The manual details how to insert the NS-2 into your signal chain using these jacks, ensuring optimal noise reduction without affecting your tone․
Properly utilizing the Send and Return allows for a more surgical approach to noise control, as detailed in the instructions․ Experimenting with placement within your effects loop can yield the best results, minimizing signal loss and maximizing noise reduction effectiveness․
Optimal Signal Chain Placement
The BOSS NS-2’s placement within your signal chain significantly impacts its effectiveness․ The manual recommends positioning the NS-2 after any overdrive, distortion, or fuzz pedals, but before delay or reverb effects․ This ensures the noise suppressor targets the noise generated by your gain stages, rather than attempting to eliminate the natural ambience of your time-based effects․
Placing it earlier in the chain might suppress your instrument’s dynamics along with the noise․ Conversely, positioning it after modulation or time-based effects could inadvertently reduce their desired textures․ The instructions emphasize experimentation, but this order generally provides the cleanest results․
For high-gain setups, utilizing the Send and Return jacks (as detailed in the manual) and placing the NS-2 within the effects loop of your amplifier is often optimal․ This isolates the noise suppression process, preserving your core tone and maximizing noise reduction․
