Flanger BL-20

Flanger BL-20's hardware predecessor may not be a household name, but its hypnotic sound and radical feature set speaks for itself. Toggle and combine multiple modulation sources, manipulate the LFO shape and stereo spread, plunge harmonic sweeps to uncharted depths. Flanger BL-20 is no ordinary analog emulation - it's an FX toolkit gone supersonic.

3 MODULATION SOURCES.

Choose between Auto (LFO), Env (internal or external) or Manual, or any combination of the 3, for an array of flanger sounds unlike anything you've ever heard.

STEREO ENHANCER.

Operate Flanger BL-20 in either mono or stereo mode, and manipulate the stereo spread of the modulated signal for ultra-wide presence in your mix.

ZERO-CROSSING.

Due to a tiny delay applied to the dry signal, the modulated signal doubles back over the original starting point, resulting in a classic deep flange with prominent 'blips' in the sound.

BBD WARMTH.

Flanger BL-20 uses authentic bucket-brigade device circuitry replication to emulate the original unit's gloriously warm analog response.

ADVANCED CONTROLS.

Change the Auto LFO shape, tweak the stereo spread - we even added an advanced function generator from Pigments. Vintage charm meets cutting-edge.

PRESETS.

A curated selection of 28 presets, giving you instant access to the energetic movement and analog brilliance of Flanger BL-20.

The flanger effect is achieved by modulating a delayed version of your signal using an LFO. Flanger BL-20 expands this principle in multiple directions.

By applying an undetectable delay to the dry signal, the modulated signal is able to reach - and eventually pass over - the original starting point of the signal. This totally cancels out certain frequencies - resulting in distinct dips in the sound. This is known as 'zero-crossing' or 'through-zero' flanging, perfect for that dynamite '80s guitar sound.

Finally, the option of multiple modulation sources gives Flanger BL-20 a uniquely animated quality. Use the default LFO, a responsive envelope follower, or a static manual override - there's nothing quite like it.

A crucial element of Flanger BL-20's sound is the bucket-brigade device circuitry emulation.

Arturia meticulously replicated this circuitry in virtual form to ensure a pristine analog response. Not only does BL-20 offer mind-blowing modulation capabilities - it adds that desirable vintage sparkle that plugins often lack.

This makes it a formidable mix sweetener, whatever your style. Enhance your rhythm guitar parts, animate your backing vocal tracks, enrich a repetitive drum loop; whatever your application, it will simply sound better.
