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 whole rack in one knob

A great lead vocal takes a whole rack. SUNDAY does that work for you. One knob.

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.

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.
