MXR M135 Smart GateOriginally designed by Scholz Research and Development — the engineering minds behind the legendary Rockman — the MXR M135 Smart Gate has been a go-to noise solution for high-gain players for decades. MXR updated the classic design with a hardwire bypass, cleaner circuitry, and a precise threshold trigger, then squeezed it down from its original half-rack footprint into a compact, road-worthy stompbox. The result is one of the most intelligent and transparent noise gates on the market, trusted by players like Zoltan Bathory of Five Finger Death Punch and Frank Iero of My Chemical Romance.What makes the Smart Gate genuinely smart is its ability to read your playing in real time and respond accordingly. When you're sustaining a chord or letting a note ring, the gate reacts slowly, allowing the natural decay to breathe without cutting it off prematurely. When your playing speeds up — fast picking, palm mutes, rhythmic chop — the gate snaps to attention and adds razor-sharp definition. This dynamic response is what separates the M135 from simpler threshold-only gates that clamp down indiscriminately and rob your playing of life and nuance.Three selectable noise reduction modes let you match the gate's character to the specific type of noise problem in your rig. Hiss mode targets high-frequency noise — ideal for hissing amps or noisy single-coil pickups. Mid mode is tuned for noisy guitar amps and moderate gain setups. Full mode handles wide-range noise across the full frequency spectrum, making it the best choice for bass rigs, extreme high-gain setups, or entire pedalboard chains. A Hi Trigger Range switch extends the Trigger Level knob's range for extremely noisy situations. Open or closed, the M135 adds virtually nothing to your signal — it simply gets out of the way.Key Features:Intelligent gate speed — Reacts slowly for sustained notes and chords; snaps fast for aggressive, rapid pickingThree noise reduction modes:Hiss — Targets high-frequency noise from amps and single-coil pickupsMid — Optimized for noisy guitar amps and moderate gain rigsFull — Wide-range reduction for bass rigs, extreme gain, or full pedalboard noiseVariable Trigger Level knob — Sets the threshold at which the gate engagesHi Trigger Range switch — Extends threshold range for extremely noisy environmentsGate LED indicator — Yellow LED lights when the gate has engagedHardwire bypass — Adds virtually no coloration to signal in bypass modePrecise threshold trigger — Accurate, responsive detection without false triggeringCompletely clean circuitry — Transparent operation with minimal signal interferenceOriginally designed by Scholz Research and DevelopmentCompact stompbox enclosure — Pedalboard friendlyPowered by 9V battery or Dunlop ECB003 AC adapter / DC Brick power supplyAll items shipped via UPS Ground where available.
