Switch over to Gate mode, and you'll experience lightning-fast responsiveness, ensuring that your precision-driven, high-gain riffs cut through the mix with unwavering clarity.

Whether you're jamming at home, rocking out on stage, or laying down tracks in the studio, the NS-1X proves itself as a versatile and user-friendly solution to vanquishing noise disturbances. Elevate your practice, live performances, and recording sessions to a new level of sonic purity with this indispensable tool in your arsenal.
