Boss NS-2 Noise Suppressor

Brand: Boss · Category: Utility · Released: 1987

The Boss utility classic for taming hiss and high-gain noise with threshold, decay, and a clever send/return loop.

The Boss NS-2 Noise Suppressor is a compact noise-reduction pedal built to reduce hiss, hum, and high-gain idle noise without simply chopping off every note. Its Threshold and Decay controls set when suppression engages and how naturally it releases, while the send/return loop lets noisy drive pedals sit inside the detector path for more targeted control.
