BOSS NS-2 Noise Suppressor
Eliminate Unwanted Noise For A Clean & Precise Performance
The BOSS NS-2 Noise Suppressor is a dedicated noise reduction pedal for electric guitar and bass, designed to eliminate unwanted hum, hiss, and buzz without compromising tone or playing dynamics. Its advanced circuitry ensures natural note decay and responsiveness, while the integrated send/return loop allows for targeted noise suppression of high-gain pedals. With user-adjustable Threshold and Decay controls, two operational modes (Reduction and Mute), a DC output for powering additional pedals, and a five-year BOSS warranty, the NS-2 offers a reliable and effective solution for achieving a cleaner, more professional sound in any setup.

The BOSS NS-2 Noise Suppressor is a compact and powerful solution for managing unwanted noise in electric guitar and bass setups. Designed specifically for musicians using gain-heavy effects or experiencing interference from power supplies and lighting, the NS-2 effectively removes hum, hiss, and buzz without affecting the tone or dynamics of the instrument. It ensures a clean signal between notes, helping players maintain a professional and focused sound in both live and studio environments.
Equipped with a built-in send/return effects loop, the NS-2 allows users to isolate and control noise from specific pedals within the chain, such as overdrives and distortions. This loop design enables the pedal to detect the clean signal while independently suppressing noise from gain-based effects, providing consistent performance regardless of pedal configuration. Its VCA-based circuitry with envelope detection technology ensures the natural decay and character of each note are preserved, delivering transparent and seamless noise suppression.
The NS-2 offers practical controls to tailor noise reduction to individual setups. The Threshold knob sets the point at which suppression begins, while the Decay control adjusts how long it takes for the sound to fade after falling below the threshold. It also includes two operational modes: Reduction mode allows the pedal to engage and disengage suppression during performance, while Mute mode fully silences the signal, ideal for tuning or switching instruments. Additional features include a DC output jack for powering other pedals and BOSS's industry-leading five-year warranty, making the NS-2 a reliable choice for any guitarist or bassist.
