online microphone feedback?

[Shimmiy]

does anyone else get some rather nasty feedback when there are 2 people on guitar in the room? if its just me and 1 person there is no feedback at all, but soon as a 3rd person joins i start hearing everything i say echoed right back to me.

any idea what the issue might be?

That's weird, although I have no idea why that might happen...

Something like this may have happened to me once or twice, would have to have it happen again to be sure.

Anyways, bump to try to get this guy an answer.
