Flanger BL-20

Arturia Flanger BL-20 is an analogue-modelled flanger plugin that turns familiar jet-like sweeps into richly animated textures. Inspired by a vintage studio processor, it recreates the warm character of bucket-brigade circuitry while adding flexible modulation controls. Blend LFO, envelope-following and manual modulation to shape anything from steady movement to effects that respond to your audio. Through-zero flanging creates pronounced dips and dramatic sweeps, making it a natural fit for bold ’80s-style guitar tones, swirling synths and experimental transitions. Mono and stereo operation, adjustable stereo spread and editable LFO shapes help you place that movement in the mix. A function generator borrowed from Pigments offers further shaping options, while 28 presets provide useful starting points. It suits producers who want vintage flanger character with room to explore more adventurous sound design.
