TL;DR — 40-second answer
The Logic Pro Final Mix is analog cohesion, not loudness. Print through Ampex ATR-102 for tape density, glue with the Shadow Hills Mastering Compressor, and shape with a Pultec EQP-1A before the Print Before Limiter stage.
UAD Ampex ATR-102 delivers analog tape density on the mix bus.
Shadow Hills Mastering Compressor provides bus glue without loudness moves.
UAD Pultec EQP-1A handles tube EQ shape before the print stage.
Loudness lives on the Limiter Bus later, never on Final Mix.
Signal Flow
Approved Chain Order
Final Mix is now the analog mastering chain: tape print, mastering compressor, and tube EQ in that order. It hands off into the Print Before Limiter stage — the sibling bus (Shadow Hills opt → Tape Eater → Spiff at -6.6 dB) that summed with Final Mix Parallel meets the limiter.
Plugin Stack
Approved Final Mix Settings
Prints the summed mix through tape emulation for analog density and cohesion.
Approved Settings
456 tape, 30 IPS, 1/2-inch width. Drive kept musical — no obvious softening of transients.
Stock Alternative — Logic Tape Delay
Zero delay, tape-style tone only for density.
The approved bus compressor on Final Mix. Glues the stereo picture without obvious pumping.
Approved Settings
Restrained gain reduction (about 1–2 dB), slow attack, Auto release. Use the transformer options for tone rather than reaching for more compression.
Stock Alternative — Logic Compressor
Vintage VCA mode, slow attack, Auto release, gain reduction around 1–2 dB.
Final tube-driven tonal shaping across the summed mix.
Approved Settings
Small classic Pultec low-boost/attenuate move plus a gentle high shelf for air. Keep the moves musical.
Stock Alternative — Logic Vintage Tube EQ
Use the Pultec-style curve subtly.
Parallel Routing
Where Final Mix Parallel actually goes
The send originates from Final Mix.
Final Mix Parallel outputs to Print Before Limiter, not back into Final Mix.
The return should sound denser, not louder. Think compressed shadow, not second master chain.
Avoid These
What no longer belongs here
God Particle, soothe2, dynamic EQ, or extra saturation on Final Mix — those live upstream in the premasters.
Any limiter or clipper on Final Mix itself. Loudness belongs on the Limiter Bus.
Broad fixes that should have been handled on tracks, groups, or the two premasters.
