Boss NS-2 Noise Suppressor and Power Supply Pedal

The NS-2 Noise Suppressor effectively eliminates noise and hum of the input signal while preserving the original sound's tonality. The natural attack and envelope are unaffected thanks to Boss's unique noise detection circuit that precisely separates the guitar sound and the noise components. When connected to an AC adapter, the NS-2 can supply power to 7 other Boss effects units via the PCS20A power connection cable(optional).
