Vintage Shure 55c, trouble getting good sound quality

Ok, so I unscrewed the 14" end and took a look. I don't know much
about this exactly (usually i fix these things by trial and error),
but it looks like there's two wires, a red and a white, and then there
is some exposed wire soldered onto the same part as the white wire.
Removing that jumper makes me nervous
And then, what is a jumper and how to I
remove it? Is it just solder than I can melt off?
Not to be mean and nasty, but I think you'd better get someone to do
the work. Watch and then you'll know more the next time you need to
make or modify a cable.
The fact that you have a red and white wire, plus an "exposed
wire" (that's the cable shield) means that you have the proper kind of
wire, but you need to remove the 1/4" plug and replace it with an
XLR.
A jumper is a piece of wire connected between two terminals on the
plug. It's represented in Figure D of the Shure data sheet by a dotted
line between pins 1 and 2 on the connector. And taking a second look
at that diagram, it looks like Pin 3 on the mic connector should go to
Pin 2 of the XLR, Pin 2 on the mic connector should go to Pin 3 of the
XLR and Pins 1 of both connectors should be connected to the cable
shield.
