[quote name='Wil' post='800791' date='Apr 9 2010, 01:01 PM']I think some mics have a phase reversal switch on them, not quite sure how this works, but I guess it's to combat this problem. Never realised it was due to the tiny delay between the sound leaving the cab and hitting the mic, though! Interesting.[/quote]
I think Phase reversal on mic's (and pre-amps) tends to be if you have 2 mics facing each other with the sound source in between (i.e. mic'ing the top and bottom of a snare or back and front of a kick drum)
The delay is obviously so small I never noticed the difference either, I just knew it didn't sound right.
