OK so after I get a good mic pre to complete the signal chain I need a good compressor. I'd like to stay under 1000 if I can. I already have the FMR so I'd like an alternative that may add warmth. THe LA-4, SC2.2, and ART Pro VLA all seem in my price range, has anyone used them? Are they warm yet don't destroy the clarity? or are there others I am missing?
