Problem with a Shure BLX24UK/SM58 mic

[PaulWarning]

Our singer bought one of these back in February at a recent gig it stopped working, sent it back to GAK who sent it to Shure, they're saying it's because of severe water ingress, but he's been very careful with it and can't see how this has happened, anybody else come across this?

Is it the Mic or reciever that is faulty?

Water ingress is a generic term, any chance it's been placed on a surface swimming in beer?

There's a general problem with a lot of circuit boards nowadays that they are particularly prone to water damage, lots of closely packed surface mounted components and multi layer circuit boards. There's also problems with boards made in China leaving the factories and getting damp whilst being shipped. Also rather than solve the problems it's increasingly common for manufacturers to have small indicator patches printed onto boards to show up any damp that gets inside. They open up repairs look for red and if it's there you've invalidated the warranty. Apple you know who you are!

You probably are onto a hiding to nothing other than that they have to show that you allowed the water in. See how obliging GAK are, then consider whether you want to pursue it through the small claims court.

He needs to stop spitting into his mic so much?

[/quote]the mic has packed up, he says he's been very careful with it, GAK seem to be following the Shure line, that he must have got liquid into it, just wondered if it had happened to anyone else.

[/quote]he's not the worst, not as bad as me lol, but if a mic packs up after 4 months because of spit it's not fit for purpose is it?

put cotton wool in the singer's cheeks to soak up his spittle

[Phil Starr]

OK it's unlikely to be the capsule given the reliability of the SM58, more likely to be the transmitter inside the mic. You need to find out.

I'd argue that the mic is not fit for purpose if moisture from the singer has penetrated that far into the mic. Either there was a manufacturing fault and it wasn't sealed properly or that there is a design fault if saliva could pentrate as far as the transmitter. If it was the capsule thenthat was faulty as Shure's have been dealing with singers spittle since 1962 (date of the first SM58)

British consumer law pretty much assumes the customer is right unless they can prove otherwise. I wouldn't expect the mic to handle immersion in standing water but it has to handle the normal spraying with saliva and unless they can prove you immersed the mic you have a good chance, especially as it is under six months old.

I'd write to them politely, pointing out that the mic hasn't been exposed to any liquids other than saliva and that it should be able to cope with this, it is an SM58 after all. You expect it to be repaired or replaced within a reasonable time mention the Consumer Rights act 2015 http://www.which.co.uk/consumer-rights/regulation/consumer-rights-act

cheers Phil I'll tell him

[Phil Starr]

good luck

our singer rang Shure direct and they've agreed to send him a new mic but cancel any further guarantee, a result I suppose but they obviously don't believe he didn't dip it into a pint
