This really sounds like an orange squeezer. its skronky and grabby and mean. I've tried it on DI guitar and it adds some DI compressor pedal tone for sure but I really like it as an effect on virtual instruments right now. You can go under the hood and screw with the frequency response, time constants, threshold and ratio too, making it more or less hifi, but the stock settings are very close to an OS if that's what you want. I am thinking of trying this on a vocal some time, maybe something recorded with a decent dynamic like an SM7 or Beta57. This is free and you might as well download it because its up to the standards of a lot of pay guitar effect plugins.
