Plug-in makers PSP have released a brand new reverb plug-in by the name of Nexcellence. The name references so-called "necklace-type" spring reverb units that were found in 1960s Hammond organs. The design involved a length of spring loosely hanging within the organ housing, and delivered a particular, desirable sound. The downside was that external knocks and vibrations could also be picked up. Later designs incorporated supporting springs to mitigate this, but that's another story.
According to PSP, the plug-in provides two different spring set processors and can use one or both of its processing engines simultaneously. PSP also say that their algorithm has improved on the original hardware by providing a handy set of parameters to let you control inherent aspects of the spring reverb — something that would have been physically impossible on the originals. Needless to say, you won't have to creep around when using it for fear of disturbing the springs, either.
The new reverb has already gained a few endorsees in the pro audio community including producer John Kurzweg who describes the sound as being "a cross between a plate, a room and spring".
PSP have put together an overview video for the Nexcellence plug-in, here, so you can hear for yourself.
The PSP Nexcellence plug-in is available now and has an introductory price of $129 until September 11, after which the price will rise to $149.
