Freeware - Fuse audio Labs VREV-666 Reverb VST Plugin

https://fuseaudiolabs.com/#/pages/product?id=301009892

The VREV-666 is an incredibly rare spring reverb from the 1960s that was initially designed to alter the apparent acoustic properties of listening environments. Originally built for the BBC, this compact studio legend oozes the typical rich, bouncy, and unpredictable vibe of a true electromechanical reverb in a very authentic way.
