Rowin LEF-326 Slow Hand Slow Gear Auto Swell Pedal True Bypass Mini Metal Ambient Guitar Effect

Product OverviewRowin LEF-326 Slow Hand is a compact analog auto volume swell pedal modeled after classic Boss SG-1 Slow Gear circuit, delivering violin-like bowed string swells without manually rolling your guitar’s volume knob. It cuts the sharp attack of each note, creating smooth, gradual rising volume textures that are core tones for ambient, post-rock, shoegaze, dream pop, blues and experimental music, fully compatible with electric guitar and bass.Equipped with two intuitive control knobs for full swell shaping:THRESHOLD: Sets the signal trigger level of the swell effect, control which note loudness activates the slow volume rise;SWELL: Adjusts the speed/depth of the volume fade-in, from subtle gentle bloom to long, slow cinematic violin swells.Pair this pedal with delay, reverb or modulation effects to craft dreamy reverse-style ambient passages and ethereal pad sounds. Matte white die-cast zinc alloy ultra-nano chassis occupies minimal space on compact pedalboards, ideal for bedroom ambient tone creation, studio post-rock recording and portable live atmospheric performances. Built with full hardwire true bypass circuit, it fully retains the raw uncolored clean tone of your instrument with zero signal loss or frequency roll-off when the swell effect is disabledReverb.This listing supplies 95% like-new units with flawless full functionality, only faint minor cosmetic scratches on housing, fully audio tested before shipment.Core Key FeaturesClassic Slow Gear Auto Volume Swell CircuitSimulates manual volume knob rolling, eliminates harsh picking attack, smooth violin-like bowed string swell texture, perfect for atmospheric ambient & shoegaze styles.Dual Independent Control KnobsTHRESHOLD: Signal sensitivity threshold, set minimum input volume to trigger swell effectSWELL: Regulates the rising speed & depth of volume fade-in, short quick bloom or long slow cinematic swellFull Hardwire True BypassUnbroken direct instrument signal path, zero background hum, no low-frequency attenuation when pedal disengagedClear Black LED Working IndicatorBright light visible under dim stage lighting to confirm swell effect active stateShockproof Matte White Die-Cast Zinc Alloy HousingUltra-small palm-sized footprint, scratch-resistant smooth white metal shell, anti-slip rubber bottom pad for stable pedalboard placementStable Power Consumption128mA working current, fully compatible with standard 9V center-negative daisy-chain power adaptersFull Technical SpecificationsModel: LEF-326 Slow Hand Slow Gear Auto Volume Swell PedalBrand: RowinEffect Type: Mini Analog Violin Swell / Slow Gear StompboxControls: THRESHOLD Sensitivity Knob, SWELL Speed/Depth KnobInput Jack: 1/4” mono audio jack, Input Impedance: 1M OhmsOutput Jack: 1/4” mono audio jack, Output Impedance: 470 OhmsWorking Current: 128mAPower 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, Gross Weight (with gift box): 273gColor: Matte 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 amplifier or INPUT jack of another effect pedal via 6.3mm audio cableTHRESHOLD Knob: Rotate clockwise to raise trigger level (only loud notes activate swell); counter-clockwise for low sensitivity (soft notes also trigger swell)SWELL Knob: Clockwise = longer, slower, deeper violin fade-in; Counter-clockwise = fast subtle quick volume bloomTrue Bypass Footswitch: Step down the footswitch to toggle Slow Hand swell effect ON / bypass OFF stateLED Indicator: Lights black when the auto volume swell effect is activatedPower Jack: Plug in DC 9V center-negative power adapter to supply power for the pedal1.
