Get new controls with the Fatso Sr.  Attack, Release, and Saturation control not found in the ELI Hardware

FATSO™ Jr./Sr. Tape Sim. & Compressor Plug-In

Get the rich sound of magnetic tape, class A transformers, and tube circuits.

Able to warmly burnish frequencies and transients, or crush them with thick saturation, the FATSO™ Jr./Sr. Tape Simulation & Compressor plug-in for UAD-2 hardware and Apollo interfaces exhaustively emulates the iconic, industry standard Empirical Labs hardware.


Used by legendary engineers George Massenburg, Ed Cherney, and Brendan O'Brien, the FATSO™ can also increase the apparent volume of your source material. The FATSO™ plug-in is officially endorsed and scrutinized for accuracy by its designer, Dave Derr.

Now You Can:

• Inject the warm, musical qualities of magnetic tape, tubes, and class A transformers to instruments or an entire mix


• Lightly color or destroy drums, vocals, and more with tube and tape saturation


• Harness “plug-in only” Tranny Saturation, Sidechain Filtering, and Stereo/Mono controls


• Dial-in a wealth of analog textures with Warmth and Spank controls

Go From Tame — to Trashed

The FATSO plug-in offers a wide palette of possibilities for adding fat analog character and cohesiveness to your DAW tracks. It’s also a creative tool, able to add varying degrees of saturation — from subtle to severe — on any source. The FATSO's Input control lets you dial in shades of harmonic generation and distortion, while the Tranny and Warmth features provide varying amounts of of tape and tube tone.

Plug-In Only Features

The FATSO plug-in’s versatility is greatly expanded with the addition of Dave Derr's custom mods. The FATSO Sr. offers a “Tranny” saturation control, Sidechain Filtering, and deeper compression parameters including Threshold, Attack and Release. These special FATSO Sr. mods are only available with the UAD plug-in version of this essential studio tool.
