This is for the pro who wants a specific, focused sound, not a do-everything utility compressor.

Frequently Asked Questions

It allows you to subtly shape the compression curve, going from a gentle, transparent feel to a more aggressive, noticeable effect – offering a wider tonal palette than fixed-slope designs.
It's a standard VU meter, ballistically responding, which means it's designed to show average signal levels – a more musical representation of perceived loudness.
While aiming for a similar aesthetic, the Herchild 660 offers a more modern control set and a slightly more focused character than the famously broad Fairchild. It’s a modern interpretation of that classic vibe, not a direct clone.
