The NS-2 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.
Add the PCS20A on the right under accessories, and you can use the NS2 to power up to 8 Boss pedals with it`s built in power supply! Get rid of those wall warts now!
