most likely it's the cable.

I've tried 2 different cables, 1 XLR and 1 1/4" jack with an XLR adaptor at the mic end, both exhibit a similar problem. No problem if I plug a guitar in though.
I have had problems with the XLR cable before though, so I'll try replacing it in any case.

can you exchange the behr*&%er for a new one ...?

Possibly, do you think it could be a fault with the mixer itself?

if it's not the cable and it's not the mic, what else is there?

i suppose it could be something in the settings ... maybe the sample rate or buffers ...

When you say static, what do you mean? Crackling, hissing, spitting noises? No way to identify the fault by 'static'. Sm58s don't get bothered by phantom.
You mentioned using a quarter inch cable? As in jack at the mixer end and then an XLR mic end??? If so - it isn't phantom causing the problem, because the combo connector does not have phantom on the jack input. If the jack work with a guitar, I wouldn't expect the noise - in fact, connecting the mic via a jack probably won't give enough level anyway. It's for guitar/line level, and a mic won't even tickle it. If it's a crackle, then the cable does seem the likely culprit.

Assuming you don't have a broken wire somewhere, a dynamic mic which does not need the phantom power (like an SM58) will not be affected by the presence of phantom power and the phantom power won't be affect by the dynamic mic. There should be no phantom power present when you connected to the ¼" input.

In my opinion, getting a 'cheap condenser mic to replace the SM58' is paddling this leaky canoe the wrong way.

I suppose it is possible you have a broken wire inside the SM58.

Yes, exactly that.

Ok. I also noticed that when connected with the 1/4" cable, the noise got louder if I touch the mic or the mic stand, which I thought was odd.

I've opened up the SM58 as far as I can and the wires look intact. I'll replace the XLR cable and see how I get on.

Thanks everyone for explaining that SM58s dont have a problem with PP, nice to know I wont need a different mic.

If touching the mic changes the noise, then a cable fault make the most sense here.

New cable solved the problem. Thanks!
