Classic FET Compressor Emulated

LSR Audio has released the VLB 525 Compressor.

A spokesperson has this to say, "The 525 compressor first appeared in the early 70's. It was integrated as a 500 module in famous american recording consoles. Over the years the 525 has become a favourite of many engineers in the recording industry, contributing its sound in numerous classic recordings.
The 525 is a character compressor that adds thickness and warmth to the signal. It is favoured on guitars, vocals, drums and bass. VLB525 further extends the hardware versatility with an adjustable attack time, and stereo link for stereo tracks or busses.
VLB525 plugin carefully simulates the electronic circuit of the hardware, including the non-linear parts such as audio transformers, discrete opamps, FET transistor... All these components have a great impact on the resulting sound.
This precise simulation reproduces all the sonic characteristics and the subtle coloration from the simulated hardware."
