The M135 Smart Gate Pedal from MXR offers three selectable noise-reduction ranges to suppress the specific range needed for your input source: Hiss for highs, Mid for mids, and Full for lows. The gate adjusts to remove the slightest hum, but allows the smallest details of your playing through, reacting gradually to long, sustained notes, and quickly to short, syncopated notes. Its fast attack time preserves your picking transients and harmonic overtones.
The Smart Gate is easy to use. Set the 3-point Noise Band Cut switch to select the noise reduction range to suppress (Hiss, Mid, Cut). The Hiss setting works well with instruments and input sources that boost the high frequency range, such as vocal mics, wind instruments, keyboards, and electric bass. The Hiss and the Mid settings are both effective on instruments with high-gain midrange boosting, such as distorted electric guitars and amplified harmonicas.
The Full setting is most effective when used to quiet input sources with
low-end hum and buzz problems, such as AC line noise, display noise, or
light dimmer noise. To quiet a rack of noisy effects, place the Smart Gate
last in the signal chain, just before the amplifier.
Use the Trigger Level knob to adjust the sensitivity of the gate threshold (indicated by a yellow Gate LED), and when needed, a Hi Trigger Range switch will extend the trigger range for extremely noisy situations. A footswitch toggles the effect on and off with true bypass, and a red LED illuminates to indicate when the effect is on.
The M135 Smart Gate pedal is powered by a single 9V battery or a 9 VDC adapter such as the Dunlop ECB003/ECB003E, or a DC Brick power supply (sold separately).
