Need urgent help with Dual mic problem!!!

Need to pick the brain of someone. Our live setup involves each of us having 2 mics on each stand. The right one for clean vox and the left one for distorted (or more accurately, lo-fi) vox. They're laid our parallel to each other from a bar fixed to the mic stand top. Kind of like this:
o o
I I
----
.I
.I

We're running both mics into our desk and then the 2 channels of the left-hand mics through loot to and from a vocal FX box.

Here's the problem: They feed back like hell. Can't stop it - it seems they're feeding back off each other. We even bought a footswitch for the FX box so that the FX would only work in short bursts when we need it, but the feedback is still horrid.

How can we counteract this? It looks goodon stage and the sound does give the songs an edge if they can be used......Is there any other way to either counteract the feedback, or to get a lo-fi sound?

If you can solve this problem, we'll be seriously in your debt.

Hope you can help!

Firstly, I deleted your duplicate post, one is enough, always!

Secondly, why use two mics, are you using two mics purely for the "look" of the show?

Feedback is caused by the signal coming from the speakers finding it's way back into the microphone, in your case two of them.

If you insist on having two microphones, then try this.

Have a switch circuit box made up which has two inputs for the mics, the switch toggles between the two mics, so only one mic is ever active. Get yourself a guitar distortion pedal and build it into the box so when the "lo-fi" channel is selected the distortion kicks. You'd be able able to set unity gain between the two by lowering or raising the gain of the effect pedal.

Any reasonable engineer would be able to build this for you, if you do not have the skills.

Basically though feedback can be eliminated with careful speaker E.Q. and positioning, the microphones will not interact with each other, they only pick up what is present.

Hope that helps.

vocal effects

If you are using a distortion similiar to guitar distortion, the system will feedback at much lower volume levels than if it were run clean. You know, how a guitar feeds back easier when it's on a higher distortion level. The fx signal that comes back out of the speaker is going to be much hotter and when the mic picks up even a little bit, it's going to run back through the system and get even hotter and well, that's what feedback is anyway, but I'm saying with that distortion, it is harder to avoid. Does that make any sense? The point being: maybe turn down the amount of distortion or try a slightly different effect that has a similar punch? Lo-fi fx are often done with just an EQ by cutting the highs and lows and boosting the mids.
