new to the grind genres so feel free to recommend well known bands

So this is assuming one is playing a smaller gig of instruments->mixer->pa system. Most mixers have the XLR ports that are preamped to support mic fidelity and quality. But the issue is- you want to run your vocals through a pitchshifter to get that low, gurgling sound. A pitchshifter typically being a pedal using a 1/4 inch jack connection as opposed to a XLR.

Do you get a 1/4 to xlr converter to plug the microphone (and associated pitch shifter) into the slot for XLR on the mixer, or do you run it through the 1/4 inch (and thus lose a lot of quality and signal) or is there some better way I'm not thinking of here?
