One knob to a
lead vocal.

SUNDAY is a complete signature vocal chain — warmth, presence, density, de-ess and a curated space — distilled into a single knob. It listens to your singer, then brings out their best.

A great lead vocal takes a whole rack.

Passive-EQ warmth, FET compression for density, leveling, multiband taming, de-essing, a plate, a room, a hall, delays — and an engineer's ears to balance it all. SUNDAY does that work for you. One knob.

How it works

STEP 01

Calibrate

Play a phrase and tap Calibrate. SUNDAY detects the singer's pitch and sibilance, and sets itself up — male or female, loud or quiet.

STEP 02

Turn one knob

Amount morphs the whole chain from clean and natural to warm, upfront and radio-ready. Loudness-matched, so you hear better — not louder.

STEP 03

Pick a space

Intimate, Anthem or Vintage — curated Room + Hall spaces that duck while you sing and bloom on the tails.

What's inside the knob

Warm analog tone

Passive-EQ low-end body and silky air — the "expensive" sheen.

Up-front presence

The vocal cuts through and leads the room, like a worship engineer set it.

Density & glue

FET-style compression for that consistent, intimate, on-the-mic feel.

Auto de-ess & de-harsh

Tames sibilance and harsh resonances — even in the reverb tails.

Curated space

Layered Room + Hall + slap that breathes with the performance.

Listens to your singer

Auto-Calibration adapts to each voice — no menu-diving.

Made for worship leads.

SUNDAY is tuned to the modern worship and pop lead sound — clear enough for the congregation to sing along, warm enough to feel like a record.

"The sound a worship engineer spends an hour dialing in — in one knob." — that's the whole idea.
