All you Mastering Eng your current hardware chain you sent down to and do most your work on right now, or your last chain you really enjoyed and any details
These posts never really make much sense... But I suppose if I had a "typically connected" chain (which I do), it's the Crane Song HEDD into a Dangerous BAX into a Crane Song IBIS into a Manley Variable-Mu into a Crane Song STC-8M into the HEDD.
Which units are actually engaged (all have hard bypasses) and the settings used -- totally dependent on what any particular mix is asking for.
