Description
BC1-THD Stereo bus compressor
The BC1-THD replaces the BC1-LTD, with a new sleek black, reorganized faceplate.
Features:
- Blend control for parallel compression.
 - All controls stepped for easy recall.
 - High Pass filter on the sidechain.
 - External sidechain input.
 - Smooth compression.
 
The THD differs from the BC1-S in that it adds:
- “Grab switch” - adds snappier more apparent compression character
 - “THD switch” - adds more overdrive and color
 - More attack settings
 - 3 selectable high pass filters

Lovely!
Purchased for its transparency, and it delivers in spades! The THD function is incredible - adds harmonic weight that is subtle but incredibly musical. Still discovering the beauty of this device. It lives on my master bus!
