I mix music within Pro Tools and Logic Pro X. I am very familiar with Waves CLA76 compressors and those are my most favourite! However I was looking for something similar, but not too heavy hitting for Guitars.
The compressor is very easy to use, and in my experience it is not hard to get a great sound from it either, provided your recorded source is all good.
I use this plugin on Guitars mainly and I love how you can get the 'tightness' and emphasis on the pick attack, but not totally kill your low end. It's a nice middle ground between the 76 and 2A.
Cons - The analogue emulation. I'm personally not a fan of this feature and don't really see a great use for adding unnecessary hiss in my tracks.
