Simple, smooth dynamics control with a signal-dependent design that stays easy to operate.
A built-in Mix knob for parallel (New York-style) compression — one reviewer wished every compressor had it; it shines on a drum bus.
An anti-clip output stage that stays clean even cranked, so it doubles as a light limiter or saturation.
A character of its own that tips its hat to the classics without copying one, yet stays clean enough for some mastering.

A color-first design rather than a transparent, surgical tool — not the first pick for detailed corrective or post work.
No model of a specific named unit, so its sound is its own rather than a known reference point.
