MXR M-135 Smart Gate Guitar Effects Pedal

Tame your hissing high-gain amp or silence your string of stompboxes with this ingenious pedal. The Smart Gate is equipped with three selectable types of noise reduction to handle virtually any type of signal. It bites down on sizzle and hum but lets the smallest detail of your playing through. With its uncanny ability to sense precisely when-and how fast-to engage, this little genius will never get in your way, so you can wring every last bit of sustain out of that chord without being cut off. The M135 features a hardwire bypass, precise threshold trigger, and amazingly clean circuitry.

Description

Three selectable noise reduction ranges
Reacts gradually to long, sustained notes and quickly to short, syncopated notes
Fast attack time preserves picking transients and harmonic overtones

Power

The MXR Smart Gate is powered by one 9-volt battery (remove bottom plate to install), a 9-volt AC adapter such as the Dunlop ECB003/ECB003E, or a DC Brick power supply

Directions

Run a cable from your guitar to the Smart Gate’s INPUT jack and run another cable from theSmart Gate’s OUTPUT jack to your amplifier.
Set the TRIGGER LEVEL knob to fully counterclockwise and use the NOISE BAND CUT switch to select the noise frequency range you want to suppress— Hiss for highs, Mid for mids, and Full for lows.
Turn the effect on by depressing the footswitch and play a note or chord and let it ring out.
Rotate the TRIGGER LEVEL knob clockwise until unwanted noise has completely died out. The yellow GATE LED will light up when the gate has engaged.
If you find yourself in an extremely noisy playing situation, push the HI TRIGGER RANGE switch to extend the range of the TRIGGER LEVEL knob.
