Like the title I want to switch my EMGs to Seymour Duncan Black Winters. I've never done it so I will paying a guitar tech at guitar center. Here's the questions. My wife will be taking the guitar in as I will work at almost every conceivable time the tech will be there. What do I need to send? Should I remove string from the guitar? Why do I obsess over little details like this? I have the pickups and 500k pots and that's it.
