Dunlop MXR M135 Smartgate Electric or Bass Effects Pedal

The minimalistic Dunlop MXR M135 Smart Gate is a noise gate pedal that excels at its single function: suppressing unwanted noise. With adaptable circuitry designed to identify and remove noise without affecting tone or sustain, it is a must-have for musicians with no love for their amps sizzling, hissing, or buzzing. The MXR Smart Gate works not only with electric guitars but bass guitars, vocal mics, and other acoustic and wind instruments that use microphones as well. Thanks to its optimized construction and built-in settings, even the noisiest sources are tamed and turned into crystal-clear signals, faithful to the musician behind them.The pedal has been designed to kill all noises generated during sound collecting and guitar effects processing. With ultra-low latency and fast attack times, this suppressor picks up short notes and acts fast while respecting long notes for optimal sustain. These fundamental features yield great tone, driving your music to its finest expression from the finest of guitars and through any rig of amplifiers and effects pedals. Best results are usually obtained placing the MXR Smart Gate just before amplifiers in an audio setup. Place it at the end of your pedal chain, stomp on the footswitch to turn it on, find the setting that kills that hissing, whooshing, or humming of your guitar, and enjoy the full clarity of your true sound. Faithful to its no-noise mantra, this effects unit features true hardwired bypass functionality for pristine audio signal output to an amp even when turned off.While sporting a simple design with little need for accessories, the Dunlop MXR M135 is packed with plenty of features. A single large Trigger Level knob sets the level of suppression needed. The yellow LED light labeled Gate indicates when the suppression function is activated and unwanted frequencies are cut off. A blue LED indicates when the pedal is turned on via the footswitch. A useful function in noisy applications or with high-gain signals such as guitars with extreme bass distortion or guitar overdrive, this noise gate pedal includes a button that extends the suppression range further for cleaner amp output. For fine-tuning your noise suppression threshold, the noise gate has a three-way selector for hiss and mid and low frequencies. This selector is sure to match the problem caused by electric guitars and other pedals in the loop, providing great noise reduction. The aluminum enclosure and switch elements of the MXR Smart Gate have been engineered with rough, on-the-road use in mind. Durable .25-inch input and output jacks clamp tight to your cables, ensuring connectivity to neighboring pedals as well as reliability. Bright LED lights lend visibility in both ultra-bright and pitch-black settings. Insert a 9V battery by simply removing the bottom plate or use power accessories such as an optional AC adapter or power supply to fire it up. The Smart Gate is the final touch of gear for any musician, polishing your final signal so it sounds as purely as intended. This pedal will make sure you're ready for hi-fi recording and large gigs regardless of how many guitar effects used.
