STAX LEF-312 Pure Analog Flanger Guitar Effect Pedal With Static Filtering True Bypass Full Metal Case--Shipped from Irvine Warehouse in California by USPS

Product Overview

STAX 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 Features
