Arguably the coolest and most unique device in the Empirical Labs arsenal, the FATSO (Full Analog Tape Simulator and Optimizer) is a digitally controlled analog device that gives musicians and engineers easy access to many of the desirable characteristics exhibited by older tube and Class A electronics and magnetic tape mediums. This two channel audio processor musically integrates frequencies and transients, increasing the apparent volume while keeping tight control over peak levels.

Hedd FATSO soundclips

Hi Guys

Just stumbled onto this site--look very nice and professional

Does anyone have any soundclip comparisions of these type devices. I hear so much about how they add warmth but even their own site won't offer side by side clips

I would love to hear side by side clips at the same amplitude if anyone has any or knows of a site that has them

Thanks guys


I understand these are two different animals.My use will be two tracks into Pro Tools.The reason I am in this predicament is I picked up a used STC-8 from a guitar mart for a good price $2400 got it all hooked up and what do you know the power switch is broke,go figure but after wiggle here wiggle there it came on.I rigged up a Royer to a MP-2NV through this STC-8 into Lucid into the HD system

LA-2A , VT747 or FATSO compressor?

Ok, I am adding another comp to my room and I wanted your opinions. I will be adding the device mainly for character, smoothness and yes I want the "tube sound" for tracking and mixing mostly midi? My options are LA-2A a VT747 a FATSO or maybe even a Peavey VCL2? My budget is just about 2k. I know they are all tube and the LA-2A is just a single channel and a bit more than 2k.

FATSO And Its Compressors!

I currently use an RNC and Crane Song Hedd for tracking my keyboards and Vocals into my DAW. I like the tube and tape emulations on the HEDD for both tracking and mixing. I was wondering if the compressors on the FATSO were pretty useable for tracking and the 2-bus. I'm not too sure is getting a FATSO would be redundant since I have way to warm and fatten things up with the Hedd.
