Behringer Noise Reducer NR300

A Pedalboard Classic to Tame Noise (Without Sacrificing Playability)

With the NR300, Behringer continues the great tradition of "noise suppressor" and noise gate pedals used to clean up a high-gain rig: hiss from distortion, buzzing from a loaded pedalboard, or the typical hum of certain single-coil pickups. The idea is simple: keep your tone and dynamics while reducing residual noise when you're not playing (or between phrases).

Who Is It For, Which Styles, and In What Contexts?

The Behringer NR300 is aimed at a wide range of musicians, from beginners discovering the joys (and limits) of gain to experienced guitarists seeking a quieter pedalboard. It is especially suited for rock, hard rock, and metal, but also fits modern blues and pop whenever a compressor, boost, or overdrive brings up the hiss.

In rehearsal and live settings, it helps achieve clean silences between riffs and controls feedback when idle. In the home studio, it makes recordings cleaner, especially when stacking multiple pedals before the amp or recording at moderate volume with heavy saturation.

Settings, Modes, and Connectivity: Essentials for an Effective Noise Gate

The NR300 gets straight to the point with clear controls. The Threshold knob sets the level at which noise reduction activates: the higher you set it, the earlier the gate "closes" (useful for high gain, adjustable on clean sounds). The Decay control adjusts the closing speed: short for very sharp, percussive cuts, longer to let notes breathe and preserve sustain.

The Mode selector lets you choose between "reduction" operation to clean the signal, and a "Mute" mode to cut the sound (ideal for instrument changes, managing a noisy pedalboard, or achieving instant silences). The Send/Return loop is a real advantage: it allows you to place your noisiest pedals in the loop so the NR300 "monitors" them and reduces noise at the source, rather than gating your entire output sound.

Sound

A good noise reduction pedal should be unobtrusive, and the NR300 is designed for that: it aims for effective noise cleaning while preserving attack, envelope, and feel under the fingers. Properly set, it leaves your tone intact when you play, then lowers background noise as soon as you release the strings. At extreme settings (very high threshold and very short decay), it can intentionally "tighten" the signal more, an effect sometimes sought after for ultra-clean, staccato riffs in modern metal.
