AudioThing has announced the release of a new audio plugin emulation of a rare BBD (bucket-brigade device) delay/echo of the ’70s.

Mantis faithfully recreates the warm and analog sound of the original Carlsbro Mantis unit. The analog modeled plugin features an echo section with 4 taps and 4 swell selectors, and a rotafaze modulation section that can mimic the wow/flutter of a tape echo or turn the unit into a unique chorus-delay.

The Mantis has eight TDA1022 chips, often associated with shorter and more precise delay, these chips are perfect for organic analog slap-back echo. The base delay time is fixed on the hardware, but in the plugin in “vintage” mode, the base delay can be set in the range of 0.512ms up to 51.2ms (as each chip has 512 stages).

In a BBD circuit, the frequency response changes depending on the base delay: brighter at faster rates, and darker at slower rates. To avoid these limitations, we also included a “modern” mode, which allows a base delay of up to 1sec (free) that is also syncable to the Host/DAW tempo.

Mantis for Windows, Mac and Linux (VST/VST3, AU, AAX and CLAP) is on sale for the intro price of 39 USD/EUR until April 30th, 2023 (regular 59 USD/EUR).

The offer is available from the AudioThing store and at distributor Plugin Boutique.
