Hey man
So. I just got a pack of Dean Markley 13-56 strings today.

When I put "d" string on. (.036), it sounds all rubbery. There is NO tone to it. And it's so loose. I can pull the guitar string, and then the "top layer" of the string moves. Anybody knows what this could be? It's the second time it's happened.
is it tuned to the correct D note?

also the windings(thats what th etp layer i assume youre talking about it) moving is new to me i dont supposed you can post a picture or a video?
Make sure it's in the right octave, if it is and your still having problems give it 5-7 days. If it still sounds odd it's probably a manufacture fault.
