Legendary Stereo Buss Compressor

The SA-384 is a 1:1 replica of the famous FX-G384 bus compressor manufactured during the 90’s. After being discontinued and replaced by a modern component these sought-after units became unobtainable…until now.

Unlike the SA-4000 MK2 which is based on the E series from the mid 80’s and uses our reverse engineered DBX 202C gold cans VCA’s the SA-384 is an authentic recreation of the bus compressor found in the center section of the G Series Console from the late 80’s using two THAT 2002 blue cans as VCA’s.

An overwhelming favorite among mix engineers, the G Comp has very likely shaped more hit records than any other over the past three decades. Strap it across your 2-bus and hear your mix get punchier, bigger, more powerful, and glued together with unmatched cohesiveness. The SA-384 Stereo Buss Compressor gives you the exact same famous character, compression behavior, and frequency response as the original G384  and  at a fraction of the price.

THAT 2002

The SA-2002 is an identical reproduction of the original THAT 2002 VCA used on every single desk from the 90’s and the FX-G384. It imparts a cleaner tone without losing the famous glue and character these units were known for. Each Stam Audio SA-2002 is built in the same old fashion as the original by hand at our lab in Chile.

Premium Capacitors and Carbon resistors.

We auditioned 16 brands of capacitors to find the best sounding ones and Elna Silmic were by far the winners; they present a wider frequency response than any other brand. The carbon resistors were the icing on the cake, known for adding distortion and imparting coloration that were present in the early construction and should not be avoided on this classic circuit.

We also took this opportunity to perform several upgrades to the original SA-384 and added the following features:

  • True stereo side chain
  • Mix Blend knob
  • HPF (5 selecting frequencies)
  • New ratio configuration (1.5 and 3.0 ratios added)
  • Transformers switch for optional MOD

Further enhance the SA-384 with an optional MOD

You have the ability to add either a “British” or “American” MOD to the SA-384 MK2

The “British” MOD adds two Carnhill Output Transformers  used on the output section of the 1073 MPA preamp and channel strip making it the perfect way to add low end and effortlessly warm up a mix.

The “American” MOD adds two SA-2520 op-amps (an exact replica of the original 2520 op amp) with 2 Steel Transformers to the signal making it the perfect way to add mid-range to your drum buss giving you the famous American sound.

Due to space constraints inside, only one MOD can be selected.

Each MOD is done for 400 USD. This includes all parts and labor.

The SA-384 has true balanced outputs.

There is no compromise in parts throughout the entire circuit, which ensures you get a compressor that behaves and sounds 100% accurate to the original. All our units are handmade and calibrated in our workshop in Chile where they get a full health check twice and burn for 24 hours and come with a 2-year warranty.

The ultimate cure for “digititis”

While plugins have come a long way and are incredibly useful, there’s a reason the top engineers still have analog gear in their racks. And some of the biggest gains to be made if you’re mixing “in the box” is to use quality hardware on your Master Buss.

When you strap the SA-384 Stereo Buss Compressor over your Master Buss, your mix will instantly glue together and sound more cohesive. Small adjustments will bring more punch, tightness, power, and size to your mix…all without sacrificing clarity. Simply put, your mixes will sound like a record should!

Legendary on the mix bus. Magic on the drum bus. It’s one of those rare pieces that just makes things sound better regardless of the musical style.

100% satisfaction guarantee – if you don’t love your SA-384, we’ll refund you

If you’ve worked on a classic SSL G Series desk and strapped the G Buss Comp across your mix, we’re extremely confident the SA-384 will put a big smile on your face every time you use it. However, if you’ve never touched the original before, as gear lovers ourselves we understand that the only way to really know if this compressor is for you, is to put it through its paces. That’s why the SA-384 Stereo Buss Compressor comes with a 30-day money back guarantee. This allows you to get it into your rack and see how it impacts your recordings. If you love it (and we think you will!), great…keep the unit and create amazing music with it. If not, no problems. Just send it back to us and we’ll fully refund your purchase. And don’t worry, either way you decide to go we will remain friends.
