C660 – Classic Tone and Dynamic Shaping
Modelled on a highly regarded modern recreation of the classic 660 compressor, and meticulously crafted to deliver smooth, detailed, and musical results. Perfect for vocals, drums, or adding subtle glue and sheen, it shines even with minimal gain reduction. Its adjustable knee ranges from ultra soft and subtle to fairly hard, giving you complete tonal control.
Two Versions for Maximum Control
-
Comp: Preserves the classic switchable release settings of the original hardware.
-
Vari Comp: Fully variable release, including extended faster timings.
Bonus Comp 76
Modeled with the 660 unit’s soft knee combined with the high-ratio hard knee of a RevF **76, both sampled together. The compression starts gently, then transitions to the hard knee at an adjustable threshold you control.
Flexible Modes
-
Clean: Transparent, no harmonics.
-
Main: Adds two harmonic orders for a richer sound.
-
Clean SHQ: CPU-intensive, optimized for final renders with the most accurate frequency response.
For full tonal fidelity, use the optional Harmonics Only program alongside Clean or Clean SHQ. There are also pass-through programs for subtle hardware coloration without compression, perfect for preamp-style subtle enhancement.

if i could only use one compressor plugin it would be this one. sounds like very expensive hardware. equally good at subtle thickening and sweetening as it at making drums, guitars, bass, and vocals explode. as good as it gets.
