Hey guys and gals. I'm new to this page. my fellow player got me into it. I have a question. I am stripping down a older guitar and I don't know anything about pickups. I am versed in electrical work, but not pickups. i am considering replacing my current set, or may be just one, like the bridge pickup my current set all have two wires each, yellow and bare, or black and bare etc. what does this mean, and what type of set would i want? I'm meaning, can I order just any set for replacement or do I need specifics, as in # of conductors, wires, etc. I'd greatly appreciate any advice. thank you gents.
