So, I have searched high and low and have not found the answer I am looking for. I recently purchased a new (lefty) Epiphone Les Paul Standard. I am very happy, but after getting the guitar home I realised not only are their old strings on the guitar, but the action is incredibly low. Resulting in crazy buzzing and in need of a new set-up to my liking. Being a beginner and only having changed the strings before. I will be doing this in the next day or two, as well as setting the intonation. I am going to try and see how much I am comfortable with before taking it back to the shop. But, my question is regarding the pickups. The low E and A string often come into contact with the neck pickup. I tried using the 'middle' screws to lower it, but instead the screws begin to come loose and out of the pickup ring. I this normal, or is this a problem? The bridge pickup works in the fashion. Appreciate any feedback!
