CostaLab Buffer
Costalab · pedal
CostaLab built its Buffer pedal around a pure Class A circuit specifically to preserve tonal nuance even across a complex, effects-heavy pedalboard, designed for two main placements: at the front of a chain packed with many pedals to protect the signal before it degrades, or at the very end just before the amp, functioning as a true line driver for clarity, power, and focus. Its ultra-high input impedance guards against the tonal thinning long cable runs or mismatched circuit impedances can cause, and CostaLab markets it for use across electric guitar, bass, and amplified acoustic instruments alike, with the pedal drawing an efficient under-20-milliamp current from a standard 9-volt supply.
