Acoustic Chorus

The Vahlbruch FX Acoustic Chorus is a chorus effects pedal designed for acoustic instruments, delivering modulation without altering the pickup signal phase. It incorporates a permanently active buffer and impedance converter for linear signal transfer, supporting passive piezo pickups and preserving a balanced, transparent output. The circuit is designed to retain the instrument’s natural response and frequency spectrum by preventing phase cancellation between the direct and amplified signals. Features: - Chorus effects pedal specialized for acoustic instruments - Permanently active buffer/impedance converter for linear signal transfer - Maintains transparent sound and frequency response - Does not alter pickup signal phase, preventing phase cancellations - Supports passive piezo pickups
