ROWIN Noise Gate Effect Pedal For Electric Guitar &Bass Ture Bypass Under Lowest Price&Highest Quality To Provide Clear Sound

Product OverviewRowin LEF-319 Noise Gate is a compact professional noise suppression stompbox specially designed to eliminate hum, hiss, interference and unwanted feedback in guitar/bass signal chains, perfectly solving noise troubles of high-gain distortion, long instrument cables and multi-pedal setups for metal, hard rock, blues and funk players.Equipped with a two-position Hard/Soft mode toggle switch and wide-range THRESHOLD control knob (-70dB ~ +10dB), it delivers two distinct noise reduction strengths to match all playing styles: Soft mode retains subtle quiet picking nuances for clean/blues tones; Hard mode provides aggressive heavy noise cutting for high-gain metal riffs to mute idle signal completely.Ultra-mini solid white die-cast zinc alloy housing occupies minimal space on crowded pedalboards, ideal for bedroom practice, studio noise cleaning and long live stage touring gigs. It adopts standard 3PDT hardwire true bypass circuit, fully preserving the original transparent raw tone of your instrument with zero signal loss, frequency roll-off or artificial tone coloration when the noise gate is disabled. Core Key FeaturesDual Hard/Soft Noise Reduction ModesSoft Mode: Gentle noise suppression, keeps delicate low-volume picking dynamics, perfect for clean, blues, jazz and light overdrive tonesHard Mode: Aggressive deep noise gating, fully cuts hum/hiss/feedback for high-gain metal, thrash and heavy distortion rigsWide Adjustable Threshold Range (-70dB ~ +10dB)Single THRESHOLD knob sets the signal trigger level of the gate; lower value = tighter noise mute, higher value = preserve soft quiet playing detailsFull 3PDT Hardwire True BypassUnbroken direct instrument signal path, zero background hum, no signal attenuation when pedal disengagedClear Red LED Working IndicatorBright light clearly visible under dim stage lighting to confirm noise gate active stateShockproof White Die-Cast Zinc Alloy HousingPalm-sized ultra-small footprint, scratch-resistant solid white metal shell, anti-slip rubber bottom pad for stable pedalboard placementStable Low Power Consumption26mA working current, fully compatible with standard 9V center-negative daisy-chain power suppliesNo Battery Support, Stable DC Power DesignDesigned for dedicated 9V center-minus adapter only, avoids unstable battery voltage noise interference Full Technical SpecificationsModel: LEF-319 Noise Gate Noise Suppressor PedalBrand: RowinEffect Type: Mini Dual-Mode Guitar & Bass Noise Gate PedalWorking Modes: Hard / Soft two-position slide toggle switchThreshold Adjustment Range: -70dB ~ +10dBControl Knob: THRESHOLDInput Jack: 1/4” mono audio jack, Input Impedance: 1M OhmsOutput Jack: 1/4” mono audio jack, Output Impedance: 470 OhmsWorking Current: 26mAPower Supply: DC 9V barrel adapter (center pin negative, outer barrel positive, adapter NOT included; battery power unsupported)Material: Die-Cast Zinc Alloy Metal ChassisDimensions: 93.5mm(D) × 42mm(W) × 52mm(H)Net Weight: 160g, Package Gross Weight: 235gColor: WhiteOEM/ODM Support: AvailableOperation InstructionsINPUT Jack: Connect your guitar/bass or output of another effect pedal with 6.3mm audio cableOUTPUT Jack: Connect to your guitar/bass amplifier or INPUT jack of another effect pedal via 6.3mm audio cableMODE Toggle SwitchSOFT: Mild noise reduction, retain subtle quiet picking details for clean & blues tonesHARD: Powerful deep noise suppression for high-gain heavy distortion & metal rigsTHRESHOLD Knob: Rotate to adjust signal trigger level; turn counter-clockwise for stricter noise mute, clockwise to keep soft quiet playing soundTrue Bypass Footswitch: Step down the footswitch to toggle noise gate ON / bypass OFF stateLED Indicator: Lights red when the noise suppression gate effect is activatedPower Jack: Plug in DC 9V center-negative power adapter to supply power for the pedal (batteries cannot be used)1.
