Stam Audio SA-76+ – Rev A, D, F & G FET Compressor/Limiter

Four Legendary 1176-Style Revisions. One Extraordinary Analog Compressor.

Why choose a single flavor of classic FET compression when you can have four?

The Stam Audio SA-76+ brings the distinctive character of four highly sought-after 1176-style revisions — Rev A, Rev D, Rev F, and Rev G — together in one remarkably versatile analog compressor/limiter. From aggressive, harmonically rich vocal compression to tight bass, explosive drums, smooth acoustic instruments, and transparent dynamic control, the SA-76+ gives engineers an enormous tonal palette without filling an entire rack.

At its core is classic FET gain reduction, complemented by premium transformers, carefully selected components, matched transistors, and revision-specific signal-path changes designed to capture the personality of these historic compressor circuits.

But Stam Audio didn't stop at vintage recreation.

With a Dry/Wet Mix control, 8-position Sidechain High-Pass Filter, True Bypass, Super Slow 20ms Attack mode, and expanded ratio options, the SA-76+ takes the classic FET compressor concept into the modern studio.

If you want the speed, punch, attitude, and unmistakable analog character associated with classic 1176 compression — but need more tonal flexibility from a single rack unit — the Stam Audio SA-76+ is built to become a serious studio workhorse.

Four Classic Compressor Personalities at Your Fingertips

The defining feature of the SA-76+ is its ability to access four distinct revisions from one hardware compressor.

Rev A — Aggressive, Colorful & Full of Attitude

Reach for Rev A when clean isn't the objective.

Inspired by the famous early "Blue Stripe" character, this revision delivers an aggressive midrange and unmistakable coloration that can bring vocals forward, make drums explode, and add attitude to bass, guitars, and room microphones.

It's the revision to reach for when a track needs to sound bigger, more exciting, and unapologetically analog.

Rev D — The Studio All-Rounder

Rev D offers a superb balance between vintage character and versatility.

It retains the speed and excitement expected from a classic FET compressor while providing a more controlled personality that works beautifully across vocals, bass, guitars, drums, and general tracking duties.

When you're unsure which revision a source needs, Rev D is an excellent place to start.

Rev F — Smooth, Refined & Musical

Switch to Rev F when you want classic FET dynamics with a gentler touch.

Its smoother character makes it particularly useful when preserving the natural detail of acoustic guitar, strings, vocals, percussion, and other transient-rich sources matters as much as controlling dynamics.

Rev G — Cleaner Dynamic Control

For applications where you want FET speed without imposing excessive coloration, Rev G provides the more transparent side of the SA-76+.

Its topology bypasses the input transformer, helping deliver cleaner dynamic control while retaining the immediacy and responsiveness that make FET compression so useful.

It's an excellent choice for acoustic instruments, detailed recordings, and sources that already have the tone you want.

Modern Controls Meet Vintage FET Compression

Dry/Wet Parallel Compression

Parallel compression no longer requires additional routing.

The SA-76+'s Dry/Wet Mix control lets you blend the compressed signal with the original signal directly from the front panel.

Crush a drum or vocal signal hard, then blend the dynamics and harmonic character underneath the dry source for density, energy, and impact without sacrificing transient definition.

8-position Sidechain High-Pass Filter

Low-frequency energy can easily make a compressor work harder than you want.

The SA-76+ incorporates an 8-position Sidechain High-Pass Filter, allowing you to reduce the compressor's sensitivity to low frequencies.

That makes it considerably easier to retain kick impact, bass weight, and low-end movement while controlling the rest of the signal.

Super Slow 20ms Attack Mode

Classic FET compressors are famous for exceptionally fast attack times. That's part of their magic — but sometimes you want the transient to breathe.

Engage the Super Slow Attack Mod and the SA-76+ extends its attack to 20ms, allowing more of the initial transient through before compression takes hold.

The result? More punch from drums, greater articulation from bass and guitars, and another completely different way to shape dynamics.

Expanded Ratio Selection

With ratio settings spanning 2:1, 4:1, 6:1, 8:1, 10:1, 12:1, 14:1, and 20:1, the SA-76+ can move from relatively gentle dynamic control to unmistakably aggressive limiting.

And when subtle isn't on the agenda, All Buttons In delivers the explosive compression character engineers have used for decades to create larger-than-life drum rooms, parallel drum buses, vocals, bass, and effects.

True Bypass

A dedicated True Bypass function makes level-matched A/B comparisons straightforward, helping you determine exactly what the compressor is contributing to your signal.

Premium Analog Components Where They Matter

The SA-76+ isn't simply designed to approximate the behavior of vintage FET compression. Its analog architecture uses carefully selected components to reproduce the transformer interaction, harmonic structure, and dynamic behavior associated with the original circuits.

The signal path incorporates a Sowter UTC O-12-style input transformer, along with Sowter and Carnhill output transformers, matched transistors, precision resistors, and premium capacitors.

The result is a compressor capable of delivering far more than gain reduction. Push the input and the SA-76+ becomes a tone-shaping instrument, adding harmonic density, transformer character, urgency, and analog weight before you've even started thinking about EQ.

Made for Vocals, Drums, Bass, Guitars & More

The SA-76+ can easily become one of the most frequently patched processors in a serious recording or mixing setup.

Vocals: Add presence, density, excitement, and controlled peaks while selecting the revision that best complements the singer.

Bass: Lock the performance into the mix while adding harmonic weight and articulation.

Kick & Snare: Use the slower attack options to preserve the initial transient while bringing up body and sustain.

Drum Rooms: Drive the compressor aggressively or engage All Buttons In for explosive room ambience.

Acoustic Guitar: Rev F and G provide excellent choices when you want dynamic control while maintaining detail and articulation.

Electric Guitar: Add density, sustain, midrange attitude, and analog character.

Parallel Compression: Use the onboard Dry/Wet control to create aggressive compression without complicated DAW or console routing.

Tracking: Capture controlled, mix-ready performances while committing genuine analog FET compression on the way in.
