Incarnation of an iconic stomp box you will surely appreciate

In bringing the classic stomp box back to life, D16 have created a must-have effect plugin that will appeal not only to performing guitarists, but to instrumentalists and producers of virtually any genre: whether it’s rock guitar riffs or melodic synth lines you’re into, you’ll find that the extreme attention to sonic detail coupled with the flexibility afforded by modern technology in Antresol make it the perfect example of what a flanger should be in the modern era. The original, conceived in the mid-70s, quickly became a benchmark for flanger-type effects by offering a uniquely rich character defined by luxuriously harmonious interacting resonances, and has been heard ever since on countless classic recordings. That’s why D16 couldn’t resist the opportunity to resurrect the soul of this classic in a thoroughly modern incarnation with Antresol.

The key element around which Antresol is designed, an analog BBD integrated circuit, proved to offer some unique challenges for a digital emulation of this type. In particular, the feedback parameter showed some weaknesses in the form of improper shapes of emerging peaks and notches in the frequency response, forcing them back to the drawing board. After much R&D, D16's Eureka moment came in the form of a much-refined BBD emulation using quasi-analog signal representation throughout, guaranteeing behavior much more akin to the original, physical circuit. While a bit chaotic, it includes all the benefits and subtleties the analog domain can offer - unlike a deterministic, classically digital algorithm - and all this without any unwanted artifacts such as aliasing (something D16 always take great pains to minimize)… and all with the rock-solid stability only digital can offer!


  • The classic flanger reborn: An iconic stompbox resurrected with exquisite attention to sonic detail and so much more

  • Features far beyond the original: You get a wide range of parameters far beyond those you could find in common flanger-type effects

  • True BBD emulation: An exceptionally accurate emulation of an impulse-controlled, solid-state analog delay line results in absolutely ideal sonic characteristics

  • Screen fit: Several UI sizes and HiDPI support for better screen fit

  • MIDI Learn for easy controller assignment
