A new plug from Softube, this is a 3 band (multi-band) compressor modeled after a Drawmer 1973.
I've never been a huge fan of MBC, but I have downloaded the trial version for this and I find it to be the best one I've used so far. I do like that you can process in M-S as well as stereo with this plug...
I have no idea how close this is to the real thing, as I've never used a real 1973 ( at least I don't recall ever using one).
Softube is offering a 20 day fully functioning trial, although an iLok is required for activation.
I find the price to be a bit on the steep side - right now they're offering an introductory price of $199, and it will go up to $299 in a month or so... or at least that's what they are saying on their site.
I will say that I have used Softube plugs before and have always been impressed. But I'll leave it to you to decide:
