Not to beat a dead worse, but I've haven't found a solid answer to this:
My guitar doesn't have a neck pick, but it has a humbucker at the bridge, does this mean pinch harmonics are going to less powerful/harder to do/impossible?
Don't bash Hip-Hop or Rap, it just makes you look like an idiot.

The sound is treblier at the bridge than at the neck, this is why most people tend to use the neck pickup for cleans and the bridge for leads.

In short, it will make it easier for you.
