Phase cancellation between vocals and guitar??/

Hey guys, I'm a total newb to recording... but to get some practice I've been recording a buddy that plays in a rockabilly/psychobilly band, and he's doing some solo stuff.... Just guitar and vocals, but in the same genre.

On one track it seems like during the chorus, there's a part where the combination of the gruff breakup of his voice, with the midrangey dirty tube amp breakup, and the fact that he sings the exact note that he plays on his guitar causes some phase issues. It seems like those parts of the song get quieter than the rest of it.

If it matters at all:

Vocal chain = Audix OM2 into Yamaha MG166CX into Lexicon Alpha

Guitar chain = Gretsch hollowbody into some pedals (delay and a drive of some sort) into an old musicman 2x10 combo, recorded with a SM58 (with the ball removed) and into the Yamaha and Lexicon

I'm working ITB with Cubase LE4... any ideas on what I can do do either remedy or mask the problem, as well as prevent it in the future??

Thanks in advance!
Steve

automate the volume of the vocal up in the areas where it seems to get masked?

Thanks! That was the first thing that came to mind, but I've never done any automation, so I wasn't sure if that was the "right" answer.

Anybody else have any info???

Were the vocals and guitar recorded at the same time in the same room?

Separate tracks, not a "live" recording.

Same room, same session, about 15 minutes apart.

Then no true phasing, as the guitar track is phasing with the guitar bleed in the vocal track, or viceversa. You may have some frequency build up at the point in the song your are talking about. Automation is your friend. Remember, whatever works is right.

Well it was tracked through phones, and there is no audible bleed... the guitar track by itself, sounds fine; as does the vocal track; but when they are played pack together, those parts where the vocals and guitar hit the same note get funky.

What happens if you flip the GTR or Vocal 180˚ in polarity?

if cancellation still exists after panning them, flip phase of guitar signal. put them back to mono, observe mix . then pan them like you want to

It's not a phase problem. It's a masking issue. Automate the volume. If that doesn't work right, automate an eq cut in the guitar to open up the vocal.

Kind of feels like one of those times when you visited the school nurse... don't worry, this may seem strange but it's actually very normal.....

uh oh. 2am gs posts while waiting for sendspace to upload files...
