Kush Audio Empirical Labs EL7 Fatso Mod - AES '09

Kush Audio has been moding the Empirical Labs EL7 Fatso for some time, and now you can buy a pre-moded fatso ready to go out of the box. The idea behind the unit was to take David Derrs Fatso, which is a fantastic 2 bus tape emulator, and give the compressor section a thorough re-working. Greg Scott (Kush Audio) set out with a few goals in mind, but mainly he wanted to increase the abilities of the EL7 Fatso as a bus compressor. Greg wanted a smooth compressor that even when pushed hard, would never sound bad. While the UBK Fatso retains the best parts of the original EL7, harmonic thickening, tape saturation and warmth control, the UBK features some impressive Compressor settings like Splat, Smooth and Glue. These presets are designed to give the Fatso the added tools to be a great compressor as well as a fantastic analog warming device. For anyone who needs a 2 bus tool to add harmonics as well as a comp to glue your mix together, this box now provides all of the tools necessary to get the job done. Call Sound Pure toll free at 888-528-9703 to discuss ordering one, or any questions you might have, or try sales@soundpure.com. Members of the Sound Pure Sales team are also experienced professional recording engineers that are glad to lend their sales experience with any of their prospective customers.

Manufacturer's Description from Empirical Labs

The UBK Fatso has the gorgeous tape-like Saturation and Harmonic Distortion of the original Fatso, as well as the same one-of-a-kind Warmth limiter for rounding and fattening spiky digital transients, topped off with a switchable Transformer for additional harmonics and overall thickening. Add in a separate Compressor section with 7 custom curves meticulously tuned by Gregory Scott, aka 'ubk', and the result is a dynamics shaping tool like no other.


Designed to give the operator the most unflinchingly musical compression regardless of the sound being processed or the amount of compression being applied, it will never pump or fold. The UBK Fatso makes easy work of the most difficult and mysterious process in sound engineering: dynamics control and transient shaping.


Vintage limiting, smooth opto leveling, transparent gain reduction, aggressive modern squeeze... whatever your vision, the UBK Fatso not only makes it possible, it makes it easy. 7 unique compressors - 4 “name” presets plus 3 “hidden gems”, produce a remarkable range of flavor, attitude, and grab, all rolled into a one-knob interface that makes it impossible to screw up.

About Manufacturer

Empirical Labs Inc. (ELI), designs and produces professional audio equipment and software. This includes equipment used in recording studios, live sound, broadcast studios and other audio production facilities etc. We also make software for digital signal processors. Most of you are here because you have heard about or used our Distressor. This product, which is our first hardware product, was designed in 1994, tested and revised for several years, and released in early 1996. The Distressor is the first in a series of audio products from ELI that will offer original features, ease of use, long product life, and a very musical audio path. Empirical Labs was started in 1988 and functioned mainly as a recording studio and electronics consulting firm. The founder, Dave Derr, was also employed at the time by Eventide as an audio engineer. Dave was part of the core design team for the H3000, H3500, and DSP4000. His experience at Eventide proved valuable for his later work. While working alongside Ken Bogdanowicz and Bob Belcher (both now at Wave Mechanics), Dave was exposed to great engineering and the modern world of digital signal processing (DSP).
