Such a great compressor. I use this alot.
At 22:01 this plugin is pulled up while M-22 explain their mastering process and say "With pre groups, where for instance we have the glue on this, this is great. This is like an SSL clone but its important for dance music that you have this side chain here so you can you can tell them not to progress anything below a certain hertz because with those big, fat ass kicks you dont want to have them compressed because they're already great so why would you compress them.more
here is another great SSL style bus compressor! Its not a 1:1 clone but it has pretty damned good sound quality. I sue this quite a bit when I don't want to use the waves one.
The Glue compressor for me it's one of my favorite compressors, because with this one you can easilly Glue your sounds with a High Quality Compression
