BOSS NS-2 Noise Suppressor Pedal

BOSS NS-2 Noise Suppressor Pedal

The BOSS NS-2 Noise Suppressor is the essential noise reduction pedal that elevates your stage and studio rig with a cleaner and more polished signal. Noise is an unavoidable challenge for electric guitar and bass players, and the NS-2 tackles everything from interference caused by lighting and power supplies to the more substantial noise associated with high-gain pedals and amp settings. The result is a quieter, more professional-sounding rig without sacrificing tone or dynamics.

What sets the NS-2 apart from conventional noise gates is its advanced analog noise detection circuitry, which suppresses noise in a smooth and organic way. Rather than the choppy, abrupt artifacts produced by simple gate designs, the NS-2 listens intelligently to the input signal and applies suppression only when needed—preserving the natural attack and decay of your instrument's tone. Threshold and Decay controls give you precise command over when suppression activates and how naturally the signal fades.

The NS-2 includes a dedicated send/return loop for integrating high-gain pedals directly into the detection circuit, dramatically improving suppression performance across even the noisiest rigs. A secondary 9V DC output jack allows the NS-2 to power other BOSS pedals when used with an optional PSA-series adapter, making it a practical and space-saving hub for the entire pedalboard. Two operating modes—Reduction and Mute—cover everything from live performance to silent tuning breaks.

Key Features

• Advanced Noise Detection: Sensitive analog circuitry suppresses noise smoothly and organically, eliminating choppy artifacts of conventional noise gates
• Send/Return Loop: Isolates high-gain pedals for optimized detection and suppression across the full signal chain
• Reduction and Mute Modes: Reduction mode toggles suppression on/off; Mute mode silences output for silent tuning or instrument changes
• THRESHOLD Control: Adjusts the signal level at which noise suppression activates
• DECAY Control: Controls the natural fade-to-silence timing after the input drops below the threshold
• 9V DC Output Jack: Powers additional BOSS pedals when used with optional PSA-series adapter
• BOSS Five-Year Warranty: Backed by BOSS's industry-leading warranty program
