It might be summer, but Fuse Audio Labs has just introduced a free spring reverb plugin. It seems that VREV-666 is based on the Grampian 666, which was built for the BBC back in the ‘60s and is capable of delivering “rich, bouncy, and unpredictable vibes”.
Realism isn’t the watchword here - it’s about adding something a bit different and audibly charismatic. The Grampian 666 had just one control, but VREV-66 adds a mix stage, pre-delay of up to 150ms and a tone EQ that attenuates the resonance of the spring system in the bass range. There’s also a limiter for taming peaks.
VREV-66 runs on PC and Mac in VST/AU/AAX formats and can be downloaded for free, though you will need to sign up for a Fuse Audio Labs account to get it.
