BOSS NS-2 Noise Suppressor Effects Pedal

The BOSS NS-2 Noise Suppressor pedal offers smooth, natural noise reduction for guitar and bass rigs, cutting hum, hiss, and unwanted background noise while preserving your play dynamics. Its sensitive analog circuitry and flexible 4-jack send/return loop make it ideal for high-gain, pedal-heavy setups, keeping tone clean and tight even under heavy distortion. A reliable, industry-trusted gate/suppressor that brings clarity and professionalism to any pedalboard or amp chain.

• Analog noise suppression pedal employing a sensitive VCA/envelope-detection circuit for smooth noise attenuation without choppy gating artifacts. 
• Dual control knobs: Threshold (sets the level at which noise suppression engages) and Decay (sets how quickly sound is cut after the signal falls below the threshold) for user-defined noise control. 
• Four-jack configuration: Input, Output, Send, and Return, enabling either simple inline use or advanced “4-cable” method gating. Ideal for isolating gain-heavy pedals for maximum noise reduction. 
• Buffered bypass design with Input impedance ~1 MΩ and Output impedance ~10 kΩ+, suitable for guitar and bass pickups and long cable runs. 
• Power via 9 V battery or optional PSA-series 9 V DC adaptor; Current draw ~20 mA, making it easy to integrate into pedalboard power supplies. 
• Includes DC out jack (when using PSA adaptor) to power additional pedals, handy for streamlined pedalboard setups. 
• Dimensions approx 73 mm × 129 mm × 59 mm, weight around 0.4 kg. Compact and pedalboard-friendly. 
• Effectively reduces noise and hum from high-gain amps, distortion chains, or guitar pickup buzz. Widely regarded as a standard tool for metal, rock, and high-gain players looking for clean output.
