Modern, improved LA-2A
I happened to purchase this puppy as part of a massive purchase of gear of many different flavors, and this module really stuck out to me. The thing about this compressor is that it can make a sound huge and saturated, like a vintage LA-2A ("100" setting ON), or it can be completely transparent and apply seamless level control without changing tone ("100" setting OFF). It's so versatile, It's extremely rare that I find myself NOT using this on anything during tracking.
Where this thing REALLY sells me though, is how fantastic it sounds on vocals. It's like an LA-2A, but more modern sounding and less intrusive to your sound. I've always had a problem with LA-2As because they tend to make the source sound a little "older," which is good in some cases, but if you're recording more modern music, that's not usually what you want. The Falcon just smoothes the source and makes it sound so much more professional and bigger... There's no way I could replace it with anything.
In terms of versatility, sound quality, and "that magic something", this has very quickly become my favorite TRACKING compressor I've ever used. (Nothing really beats an 1176 or Distressor for mixing)
