Not all compressors are the same. Learn the four main types—VCA, FET, Optical, Vari-Mu—and discover legendary units like the 1176, Distressor, LA-2A, and Fairchild that shaped the sound of music.
Compressor vs Limiter: What’s The Difference?
Main Compressor Types
VCA (Voltage Controlled Amplifier)
Fast and clean, great for tight control. Perfect on drum groups, bass, or bus compression. Works like a fine point brush—precise, punchy, yet mostly transparent.
FET (Field Effect Transistor)
Ultra-fast and colorful. Adds grit, energy, and snap. Ideal for drums or aggressive vocals. Think of it as an expressive pen that gives “life” and attitude.
Optical (Opto)
Smooth and musical with soft attack—thanks to light-based gain control. Best on vocals and bass when you want a gentle, natural ride instead of tight control.
Vari-Mu (Tube Style)
Vintage warmth with organic compression. Slower and thicker, full of character. Perfect for mastering or giving glue to your mix.
