Fair point. That was the conclusion I’ve been reading here and elsewhere too (phase getting mangled a lot during recording, or one instrument/track being in opposite phase to the other). I do still want to maintain absolute phase though for the few albums that do maintain it properly, however. Those that don’t will probably just sound just that tiny bit different from before. I’m probably coming more at it from a more me-being-OCD-about-stuff standpoint though. Maybe what I’m trying to say is, give it a shot especially if you know your amp is polarity inverting. Worst case you can just toggle it back off. The CTH is just as good an amp despite the phase flip though, but I just never thought it would be this noticeable.
