The Golden Rule
PLUGIN ON SEND = 100% WET ALWAYS
Set Mix to 100% WET on every reverb/delay in a send bus. Dry signal already exists on source. Any dry on send return = phase issues, comb filtering.
⚠ NEVER set Mix below 100% on a send bus plugin.

Pro Strategies
HP FILTER ALWAYS
HP at 180–220Hz before every reverb. Low-freq reverb = mud the ear cannot localize.
PRE-DELAY RULES
Short (10–20ms) for intimate, dotted-note for spacious. Dry cuts through, reverb supports.
AUTOMATE SENDS
Pull down in verses, push up in chorus. Dynamic space — the mix breathes with the song.
PARALLEL COMPRESSION
After reverb return: comp slow attack 80ms, fast release 200ms, 4:1. Glues reverb to dry.
SHARED REVERB BUS
Use one shared reverb for vocals, snare, guitar. Same room = cohesion.
DE-ESS THE REVERB
De-esser before the reverb plugin on send. Stops "S/T" creating washy tail.
Mastering Reality
Rule #1
Mastering Does Not Add Reverb
If your mix needs reverb at mastering, the mix failed. Pro engineers apply zero reverb to master bus on 99% of records.
⚠ Thinking of adding reverb on master bus? Stop. Fix the mix.
Rule #2
Stereo Width & Reverb Bleed
If Side > Mid in 200–500Hz, you have reverb mud destroying width. Fix: HP reverb sends at 250Hz.
✓ Side should be 3–6dB lower than Mid below 300Hz.
Rule #3
True Peak & Reverb Tails
Long tails add RMS that limiter sees as peaks. Tighten decays or add soft clip before limiter.
✓ TARGETS: –14 LUFS / –1.0 dBTP (streaming)
