    shure 585SA unisphere opening

    Hello i have this mic with me a old shure 585SA unisphere A

    unisphere-dynamic-mic-585sa-microphone-shure-bros-inc-35543662-jpg

    so im trying to open it and change the internal wires to a more superior quality wires to make little improovement

    i opened it and removed the screw from outside of the mic looked inside and the switch on off still seems to be attached to the inside of the microphone by some glue rubbered-foam, im thinking to use a plier to push the switch out but im kind of worry about doint that, also is there more thing inside the mic like small tranformers or something? im afraid after removing the switch i cannot remove the transformer, i know in the bottom of the mic there a soldering but its easily removable. thanks for any help.

    Using "superior quality wires" isn't going to improve the mic.

    Hi,
    I think you'd need to remove both screws to remove the switch assembly.
    If there's any glue holding it you should then be able to break that seal by pushing the switch in, gently, from the outside.

    What they said, though ^^.
    Unless the wiring is damaged somehow, replacing it isn't going to make any difference to the microphone.

    To be honest, that mic was never a patch on the 565 so the slightly dull and tiny sound is quite normal. Normally mics are dull OR tinny but that mic managed both!

    LOL. That should have been on their promotional material at the time ^^.

    If there's a transformer in there it's probably set in glue and tricky to remove.
    Really, I'm not sure there'd be any reason to remove it unless it was broken.

    I guess if I had to I'd remove all plastics then heat up the outer metal barrel and hope that the mass of glue softens up enough to slide out?
    Never done it...Just thinking out loud.

    It was some kind of epoxy I think. I had a 515 that was high impedance and I tried to prise out the transformer and wrecked it. The potting compound was hard and brittle. The important thing here is to reinforce the advice that NOTHING inside, bar that transformer has ANY impact on quality. Changing an inch or two of cable does absolutely nothing at all to this mic, or indeed, any mic!

    Not sure why you're worrying - sounds very close if not so close I cannot tell. Amazing for such an ancient mic!
