Boss NS-1X Noise Suppressor Pedal

Noisy signal chain? Not with this pedal in your rig. The Boss NS-1X nixes noise with a super-fast gate, smart noise suppression, and a handy mute switch.

The Boss NS-1X Noise Suppressor is the next-generation noise reducer and ultra-fast gate powered by advanced MDP technology. 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.

Cutting-Edge Noise Suppression
Background noise can be problematic with guitar and bass, particularly in high-gain setups. The proprietary MDP approach used in the NS-1X delivers fast, transparent operation in every application, eliminating the unnatural attack and decay artifacts that can be introduced with standard noise suppression systems. High-speed digital technology analyzes the input signal on multiple levels in real time, enabling ultra-detailed processing that provides just the right amount of noise reduction for any playing style or performance venue.

Maximum Versatility
The NS-1X features multiple operation modes to fine-tune the noise suppression for your needs.

Reduction--This mode provides gentle noise suppression that works with most instruments and playing styles. The note decay is natural and noise-free with all pickup types, including low-output read more single coils.

Gate--Ideal for high-gain sounds, this mode immediately silences the sound when no signal is present. MDP provides a lightning-fast response that no other noise reduction pedal can deliver, ensuring a natural playing feel and punchy note attack for percussive djent riffs, sweep picking, and legato tapping techniques.

Mute--This mode turns the pedal's bypass setting into a convenient mute switch for changing instruments, tuning, and set breaks. The NS-1X will operate in either Reduction or Gate mode when the pedal switch is off, assignable using a simple power-up procedure.

Quick and Easy Operation
With intuitive controls and a multi-LED indicator, you can dial in your perfect noise suppression profile in seconds.

Threshold--Determines the level when the noise suppression begins. In Reduction mode, start with the knob at the lowest setting and turn it clockwise until the noise disappears. In Gate mode, start at the highest setting and gradually turn the knob down until you achieve the attack response that feels right to you.

Decay--Determines when the selected mode reaches maximum noise suppression. Start at the lowest setting, then turn the knob clockwise if needed to achieve a more natural decay.
