Rowin LEF-302B ODRIVE-II 2 Mode TS Overdrive Pedal True Bypass Mini Metal Guitar Effect

Product OverviewRowin LEF-302B ODRIVE-II is a compact analog Tube Screamer-style overdrive pedal built for blues, classic rock and country guitar & bass players. Equipped with a 2-position Warm/Hot toggle switch, it delivers two distinct overdrive voices: warm smooth vintage midrange boost and tighter punchy hot crunch for rhythm riffs and singing leads. Three full independent knobs precisely control drive intensity, tonal brightness and output volume, letting users dial transparent clean boost, mild blues break-up or thick medium overdrive tones. Rugged aviation aluminum mini chassis saves massive pedalboard space for bedroom practice, studio tracking and long live touring gigs. Adopts standard hardwire true bypass circuit, completely retains raw clean instrument tone with zero volume drop or tone coloration when bypassed. Core Key Features2-Way Mode Toggle Switch (Two Overdrive Voices)Warm: Classic smooth TS overdrive, plump warm midrange, soft natural harmonic saturation for vintage blues & clean boostHot: Tighter boosted crunch, firmer low-end punch, more aggressive saturation for classic rock & hard rock rhythm partsThree Independent Tone Shaping KnobsGAIN: Adjust overdrive intensity from subtle transparent boost to thick medium warm crunchTONE: Rotate frequency balance from dark thick mid-heavy tone to sharp bright cutting treble leadsLEVEL: Master output volume, match clean amp channel volume for seamless tone switchingAuthentic JCR4558 Analog Tube Screamer CircuitRich natural midrange hump signature, preserves full dynamic response of single-coil & humbucker pickups, no harsh digital artifactsFull Hardwire True BypassUnbroken direct instrument signal path, zero hum, no signal attenuation when pedal disengagedClear Red LED Status IndicatorBright light clearly visible under dim stage lighting to confirm active effect stateShockproof Aviation Aluminum HousingPalm-sized ultra-small footprint, scratch-resistant solid red metal shell, anti-slip rubber bottom pad for stable pedalboard placementUltra Low Power ConsumptionOnly 7–8mA working current, stable to run with daisy-chain 9V power suppliesFull Technical SpecificationsModel: LEF-302B (ODRIVE-II)Brand: RowinEffect Type: Analog Tube Screamer 2-Mode Overdrive PedalMode Selection: Warm / Hot 2-position slide toggleControls: GAIN / TONE / LEVELInput Jack: 1/4” mono, Input Impedance: 520K OhmsOutput Jack: 1/4” mono, Output Impedance: 12K OhmsWorking Current: 7~8mAPower Supply: DC 9V center-negative barrel plug (adapter NOT included)Material: Aviation Aluminum Alloy Metal ChassisDimensions: 95(D) × 45(W) × 48(H) mmNet Weight: 147gPackage Total Weight: 221gCompliance Certifications: FCC VOC, CE EMC/LVD, RoHS CertifiedPackage Includes1 × Rowin LEF-302B ODRIVE-II Tube Screamer Overdrive Pedal1 × English User Manual1.
