Fuse Audio Labs has released the free VPRE-72, a virtual tube preamp plug-in for macOS and Windows in VST2, VST3, AU and AAX plug-in formats.
Fuse Audio Labs say:
The V72 will always remain a benchmark in preamp design in terms of engineering and sound characteristics, but getting hold of one these days will likely set you back a small fortune. Fortunately, it doesn't have to be that way... which is why we are happy to make its tube tone available for anyone's DAW absolutely for free.
