Could this cause phase issues?

Hey guys. Recording a band at the moment and on a few songs we didnt do two takes for rhythm guit tracks to pan L and R. So im going to duplicate the one rhythm track, send one left and right, and put i slight time shift on the one to give it more of a stereo feel. I was just wondering tho, could this cause phase probs between the two tracks at all?

Probably not.

As long as they stay hard panned, +/- a few things happen.

At 1-2 ms the effect is of an image panned toward the earlier of the pair and it takes a significant gain boost on the delayed one to 'compensate' back to 'the two equal'. This is Hass pan and the effect continues out to several ms to about 15 or so (going from memory, try it) where it begins to also take on 'one event, one side direct one side ambient' feel.
IIRC out at 20-30 it just starts being noticeable as a separate event.
All of them have problematic side effects.
Have fun.

nah, i'd say go ahead and do it, play around with the amount you separate the 2 tracks and see what sounds good. f**k the book, go with your ears!

i personally use this effect a lot, particular in electronic music.

i usually like between 10-30ms, depending.

and yes, summed to mono there is a large chance of some phasing/comb-filtering/cancellation and maybe even a little *constructive* reinforcement, dependent on several factors.

i subscribe to the school of thought that presumes that even the crappiest playback systems are probably in stereo these days, and dont worry about it too much.
