Boss NS-1X Noise Suppressor — Intelligent Noise Reduction for Guitar and Bass

The Boss NS-1X is a compact noise suppressor pedal designed to eliminate hum, hiss, and buzz from guitar and bass rigs without affecting playing feel or natural tone. Powered by BOSS's proprietary MDP (Multi-Dimensional Processing) technology, the unit analyzes frequency content, dynamics, and playing characteristics in real time, then applies the precise amount of noise reduction needed for the moment. This model works equally well for standard six-string guitars, extended-range instruments, bass, and keyboards.

What Sets the NS-1X Apart from Conventional Noise Gates

Most noise gates switch on and off with audible artifacts, but the NS-1X uses MDP to deliver ultra-fast, transparent operation that preserves attack and decay. The pedal's Send/Return loop is a rare feature in this category, allowing the circuitry to detect your clean input signal while separately gating the noise generated by drive pedals placed inside the loop. A color-coded Reduction indicator dynamically displays the current suppression status, giving players immediate visual feedback on stage.

Signal Processing — How MDP Eliminates Noise

The internal engine runs at a 48 kHz sampling rate with 24-bit AD conversion using Roland's Adaptive Focus method, then processes audio at 32-bit floating point before 32-bit DA conversion. This high-resolution pipeline is what allows the pedal to react instantly to note onsets without choking sustain or dulling transients.

• Sampling Frequency: 48 kHz — captures the full bandwidth of guitar and bass without aliasing
• AD Conversion: 24-bit + AF method — Roland's Adaptive Focus method improves signal-to-noise ratio on the input stage
• Processing: 32-bit floating point — headroom for high-gain signals without digital clipping

Controls and Modes — Dialing in the Right Suppression Profile

Four top-panel knobs give access to every parameter, and a Mode selector switches between three distinct behaviors. Reduction mode handles everyday cleanup, Gate mode delivers ultra-fast response for tapping and sweep picking, and Mute mode turns the footswitch into a silent tuning break.

• Mode knob: Reduction / Gate / Mute — three behaviors optimized for different playing situations
• Damp knob: controls maximum reduction strength — higher values silence more noise, lower values preserve natural decay
• Threshold knob: sets the trigger level — determines when the gate opens and closes
• Decay knob: controls release time — fast decay for tight high-gain riffs, slow decay for natural note tails

I/O, Power, and Physical Specs

The unit uses standard 6.3 mm TS jacks on input, output, send, and return, plus a DC Out jack for distributing power to another pedal via an optional PSA adaptor and PCS-20A parallel cable. Buffered bypass preserves signal integrity in long cable runs and complex pedal chains.

• Inputs: 6.3 mm TS jack (Input + Return) — instrument-level signal, 1 M ohm impedance
• Outputs: 6.3 mm TS jack (Output + Send) — 1 k ohm output impedance, 10 k ohm minimum recommended load
• Power: 9V battery (6LR61) or PSA-series AC adaptor, 60 mA current draw — approximately 6.5 hours of battery life under continuous use
• Dimensions: 73 x 129 x 59 mm — standard BOSS compact footprint
• Weight: 460 g — including battery, fits any standard pedalboard
