I guess I'll provide the dissenting opinion.
First, the Fatso is a great piece of gear. Well made, beautifully designed and engineered, first class. I owned one for a brief time and then sent it back to my dealer in exchange for a pair of Distressors, which I still own and love years later.
What I liked about the Fatso was the "warmth" control. That is truly a great feature and one I would have liked to keep in my studio, but $2,000 is a lot to pay for that one feature. The "warmth" feature is brilliant at taking harshness out of digital sources like synths, it softens them up interactively and leaves them a little more rounded out and pleasant to listen to. It's a great thing, and I wish I could get just that one function in a box for $500, minus everything else.
The other features on the Fatso are not as compelling, at least for me. The compressor, while good, does not offer enough control to be truly useful as a compressor in most situations. The 'tranny" feature is one that I frankly could never hear. I wondered if it was doing anything at all, or if it was just sort of a placebo thing.
I'm sure the Fatso is more useful for those people who are recording and mixing completely in the box with no hardware outboard. But for me, who uses an analog mixer and hardware outboard, I've already got that analog signal path and the Fatso just didn't do it for me.
The Distressor is another story, I love my Distressors! What great units those are. I've also checked out
the Lil Freq eq in person and that's on my short list as well.
The Fatso is just one of those units that either it works for you in your situation or it doesn't. There are those that love it, and I respect their opinion because it is a great piece of gear. However, it's not a slam dunk for everyone, and you should definitely try before you buy if possible.
Also, I personally don't consider resale when buying gear. It's the last thing you should be thinking about when buying gear, in my opinion. The only consideration that's important is whether the gear sounds good to you and will help you to accomplish your musical goals.
