Rowin LEF-312 Pure Analog Flanger Guitar Effect Pedal With Static Filtering True Bypass Full Metal Case

Product OverviewRowin LEF-312 is a compact full analog vintage flanger modulation pedal, delivering classic swirling comb-filter flanging tones popular in 70s psychedelic, indie, blues and clean rock music, compatible with both electric guitar and bass. Equipped with a 2-position Normal/Filter toggle switch, it provides two distinct flanger textures: mild subtle sweeping flang and deep warped vortex-style heavy flanging. Three full independent knobs allow full-range tone shaping to dial from gentle subtle spatial shimmer to wild trippy rotating vortex modulation. Rugged die-cast zinc alloy mini chassis drastically saves pedalboard space for bedroom practice, studio tracking and long live touring gigs. Adopts full hardwire true bypass circuit, completely retains raw clean instrument tone with zero volume drop, signal loss or unwanted tone coloration when bypassed. Core Key Features2-Way Mode Toggle Switch (Two Flanger Voices)Normal: Gentle mild sweeping flanging, subtle soft spatial movement for clean rhythm guitar and ambient tracksFilter: Deep enhanced comb-filter warp, thick swirling vortex flang with dramatic depth for psychedelic leadsThree Independent Tone Shaping KnobsCOLOR: Adjust tonal character, shift from dark warm muted flang to bright sharp airy high-frequency sweepRATE: Control modulation speed, ultra-slow subtle pulse up to fast frantic swirling rotationRANGE: Adjust flanging depth width, narrow light ripple to wide full immersive vortex effectAuthentic Pure Analog Flanger CircuitNatural organic comb-filter modulation, no harsh digital thin artifacts, fully preserves low-end bass response for bass guitarFull Hardwire True BypassUnbroken direct instrument signal path, zero hum, no signal attenuation when pedal disengagedClear Blue LED Status IndicatorBright light clearly visible under dim stage lighting to confirm active effect stateShockproof Black Die-Cast Zinc Alloy HousingPalm-sized ultra-small footprint, scratch-resistant solid black metal shell, anti-slip rubber bottom pad for stable pedalboard placementStable Low Power ConsumptionOnly 13mA working current, fully compatible with standard 9V center-negative daisy-chain power suppliesFull Technical SpecificationsModel: LEF-312 Vintage Analog FlangerBrand: RowinEffect Type: Pure Analog Dual-Mode Flanger Modulation PedalMode Selection: Normal / Filter 2-position slide toggleControls: COLOR / RATE / RANGEInput Jack: 1/4” mono, Input Impedance: 1M OhmsOutput Jack: 1/4” mono, Output Impedance: 520 OhmsWorking Current: 13mAPower Supply: DC 9V center-negative barrel plug (adapter NOT included)Material: Die-Cast Zinc Alloy Metal ChassisDimensions: 95(D) × 45(W) × 48(H) mmNet Weight: 206gPackage Total Weight: 240gCompliance Certifications: FCC VOC, CE EMC/LVD, RoHS CertifiedPackage Includes1 × Rowin LEF-312 Vintage Analog Flanger Pedal1 × English User Manual1.
