The FATSO Just Got Fatter!

Get to know them!

Have you already heard of the mind-blowingly fat and warm sounds you can pull out of the Empirical Labs FATSO? It's like taking your sound straight out of the digital world and putting it back in that round and full analog domain. And because of that, the FATSO has been a studio mainstay for years. In fact, the folks over at KuSh Audio loved theirs so much, they thought it'd be fun to find a way to tweak it to add even more features to their already-favorite character compressor. Meet the UBK FATSO.

The goal behind the UBK FATSO was this: find a way to create a collection of fixed-setting compressors that could all around just get the job done, no matter the source. Beyond that, each preset compressor had to have its own distinct flavor and vibe so engineers would have the right palette of colors and "grab" at the ready, no matter what challenges a session presented. They succeeded.

In addition to all the tone-sweetening characteristics you'll find on the classic FATSO (which is at the heart of this hot-rodded version), the UBK FATSO add three brand-new presents, meticulously crafted and tuned by ear. You've got "Splat," an API console-inspired compression setting that can enhance anything but really takes vocals and electric guitars to a thick, creamy edge when you dig into it.

Up next is the "Smooth" setting - essentially classic limiting with a special twist. The goal was to make a "tracking-style" limiter that helped you, the engineer, shave around 6-10dB off the peaks, without sounding like too much happened - just an all-around sweetness and better-behaving tracks. With your tracks through this setting, you'll find you need less EQ and compression; things just fit. But go on and abuse the setting to more-than-pleasant musical results.

Finally, there's the "Glue" setting. Put any earth-shakingly low source through this setting, and you won't believe it. The bass locks into place. It sounds clean, clear, and loud without getting in the way of the rest of your mix. Your bass, in a word, is "glue." It just sticks right where it needs to be. Of course, you'll be happy with it on a bunch of other instruments.

If you're looking for the ultimate in warmth, roundness, and unbelievably musical compression - the UBK FATSO is your pick. It has all the best qualities of the FATSO, with an extra dose of perfectly tuned "squeeze" to help your tracks really stand out.

KuSh Audio UBK FATSO 2-channel Analog Tape Simulator Features at a Glance:
  • Offers the same design as the Empirical Labs FATSO, with six new preset compression curves designed by UBK (with the blessing of Dave Derr of Empirical Labs)
  • Modes are "Splat," "Smooth," and "Glue"
  • Soft clip features modeled after broadband tape saturation. Smooth clipping up to 20% THD
  • User programmable high frequency saturation

  • Four compression modes - One for tracking, one general purpose, one "bus" compressor, and SPANK (see below). All LINKABLE!
  • SPANK! - An additional limiter that musically smashes the dynamic range, and can be used to stop clipping before digital recorders

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
