Flanger BL-20

Arturia

The Flanger BL-20 is a stereo flanger plug-in emulating a legendary English vintage bucket-brigade delay-based flanger unit from the late 1970s, renowned among world-class studios and artists. It combines classic warm analog tone with three independent modulation sources (LFO, manual control, and envelope follower) plus advanced features like a function generator, hi-pass filter, and stereo offset control for creative depth beyond the original hardware.
