Awesomely versatile analog hardware!
The UBK Fatso, now known as the Wave Fatso ( same exact product) was my first analog outboard unit. I now have a few other units including an 1176, CL1B, SSL buss comp, and APi 2500, and I still love and use this unit as much as I did when I got it.
The compression presets sound amazing and are very versatile. You can use this box for compressing any individual sound, group, or whole mix and it sounds great. The lack of attack and release controls are not an issue at all due to the fact that a great deal of thought went into tweaking the presets. Reading the manual and experimenting and using your ears is the key with this unit.
The high frequency limiter is very versatile as well and can be used for de essing vocals, taming overheads, and generally warming up sounds. It's a really cool feature that I use a lot more than I thought I would.
The trafo button adds some low girth and thickens things up. In combination with the high frequency limiter you can really thicken up sounds in a pleasing way.
Perhaps now my favorite feature is the saturation. I use it on almost every mix on synths, drums, and sometimes even the whole mix. Analog saturation just sounds really good, and so much better than anything digital can do, in my opinion. While the plugin version is also great, I really do prefer the real thing.
This is a great unit to have and you will see it in a lot of studios that have walls of other outboard. It really holds its own. It's great as a first outboard compressor due to its great versatility and since its also incredibly easy to use.
