Vocal reverb sounding muddy? Don’t send so much bass to the reverb. Use EQ before the reverb and take out everything below 3,000 Hz. This gives a nice, bright splash on the plosives and hard consonant sounds. This can make the words more intelligible in a busy mix, too.
Put a delay before your reverb and set it to a 100% short delay with no feedback. Send a vocal line to the delay and then on to the reverb. In the mix, you’ll first hear the dry vocal. The delay line then creates a gap before the reverb begins. This makes the room seem bigger, without needing a long (read: muddy) reverb time. Adjust the delay time to fit your music. On choppy vocals it’s cool. Dry sound … silence … reverb splash.
