A stereo flanger modelled on a mid-1970s analog stompbox flanger, built around an emulation of its bucket-brigade (BBD) delay line.
It covers classic pedal flanging on guitars and synths, and its stereo LFO and mid/side mode extend it to wider, more modern sweeps.

What it does
Antresol is a stereo flanger that emulates a classic analog stompbox flanger from the mid-1970s, pairing a detailed bucket-brigade delay model with digital extras.
- BBD emulation: an impulse-controlled analog delay line modelled in detail for the vintage pedal sound.
- Stereo LFO: adjustable phase between channels, host tempo sync, and the option to unlink the left and right channels.
- Mistress mode: automatically handles mix and feedback for the classic pedal character.
- M/S mode: switch between left/right and mid/side processing, with a channel crossfade control.
- Extras: 78 presets, MIDI Learn and resizable HiDPI interface.

When to use it
A good choice when you want authentic 1970s pedal flanging with more stereo control than the original, on guitars, synths and drum loops. For a studio-rack tape-flange sound, the rated Instant Flanger Mk II is the more direct option; Antresol is the stompbox alternative.
What producers say
- modwheel (2026) called it the most faithful stompbox circuit in its flanger roundup, while noting high CPU use for a flanger and small interface controls.
