Get the Rich Sound of Magnetic Tape

Warmly burnish frequencies and transients, or crush them with thick saturation using the FATSO Jr./Sr. Tape Sim. & Compressor. Used by legendary engineers with credits from Willie Nelson and Bonnie Raitt to AC/DC, Pearl Jam, and Soundgarden the FATSO UAD plug-in is officially endorsed and scrutinized for accuracy by its designer, Dave Derr.

Go From Tame to Trashed

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

Access Plug-In Exclusive Features

The FATSO plug-in’s versatility goes even deeper with the addition of custom mods — including a “Tranny” saturation control, Sidechain Filter, 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 too

What They Say

And the FATSO Sr. That’s the [FATSO jr.] companion plug-in. Yeah, that is super, super cool.

The new FATSO Jr/Sr [plug-in] is amazing. It may be the only dynamics module you need — it’s that versatile.

    FAT!

    It's main downside is that it's sort of quickly doing too much but when you use this thing subtly, it's one of the better thickeners Ive used in over 20 years of engineering. It's got the good things of tape, saturation a d compression without many of the downsides... Great!

    Outdated with blurry GUI

    It's not worth the money because it's totally outdated. The GUI resolution is like it was 20 years ago, totally blurry. The algorithm hasn't been developed further either. $149 is more than a steep price for this plugin, especially since it's not even available in a UADx version. There's nothing more to say about it. But it's been six years since Apple Silicon came on the market, and this is one of those plugins that still isn't native.

    FATSO Jr./Sr.

    FATSO has become a go-to tool for adding controlled saturation and density, especially on drums and buses, without losing punch or clarity.

    The best of the best

    This was one of those by-reputation impulse purchases which turned out to be a must have. Love how it gives polish and punch.

    Expect to use this a lot 🔥
