LR Baggs Feedback Master Active Preamp & Feedback Eliminator - Used
The LR Baggs Feedback Master is a high-performance, studio-grade active preamp and feedback eliminator built for acoustic guitarists, upright bassists, and multi-instrumentalists who need absolute tonal control in high-volume live environments. Engineered with a pure Class-A all-discrete analog circuit, the Feedback Master acts as a crystal-clear buffer preamp while surgically neutralizing low-end acoustic resonant feedback without compromising your instrument's natural tone.
Whether you are performing on stage or recording in the studio, this pedal provides precise frequency attenuation through dual Garrett Null sweepable notch filters and an integrated phase inversion switch. Designed to pair seamlessly with both active and passive acoustic pickup systems, it is an essential acoustic pedalboard accessory for gigging musicians.
