Clean and Clear!
For the personal "acoustic" project recording that I do, the BC1-S is a great "set it and forget it" stereo VCA "glue-gun" that stays powered up on the 2 bus that I mix into. The BC1-S has replaced the Var-Mu as my primary mix bus compressor. I find the BC1-S pulls the mix together in a pleasingly clean and transparent way, where the Var-Mu in comparison colors the sound a tad too dark and thick for my personal preferences.
To give up my TK Audio BC1-S, "you would have to pry it from my cold dead and calloused fingers.".- So go order your own!
