Noise No More

Powered by advanced BOSS MDP technology, the NS-1X intelligently silences noise without affecting the natural tone and playing feel of your guitar or bass. Reduction mode keeps your rig quiet in any general playing setup, while Gate mode provides ultra-fast performance to ensure that precision, high-gain riffs remain sharp and distinct. Versatile and easy to use, the NS-1X is an essential tool for defeating noise issues while practicing, performing, and recording.
