Hi guys!
I have a doubt about the polarity of the wires of the music cables.
The cables are composed by two wires, a internal one, and another that is surrounding the other (shield).
I was wondering wich wire is the positive and wich one is the negative.

thank you!

There are, unless I'm mistaken, two wires in the middle plus a shield around the outside.

i have in my hand the sectioned guitar cable, and it has the middle one and the shield, that means that it is mono, and yours is stereo. The TRS connector (Tip, Ring, Sleeve) of the guitar is mono, therefore it only has two wires and two terminals (tip and sleeve)

My question is, wich one is the negative, the middle one, or the shield?

^^The first one is very expensive cable with a non-standard design, the second doesn't have a shield (speaker cable).
Most guitar cables just have one conductor in the center.

As I said before, the shield is grounded. It cannot shield from anything if it's positive.

i'm sorry but my english is not as good as i want it to be, the only meaning of grounded that i know is similar to punished xD. wich i guess it is not the real meaning...

the shield is negative, right??

Yes, the shield is negative.
You may know grounded as "earthed" or something similar.
