I have noticed for sometime now that when I pull a string, you can hear the sound of my finger hitting the string.

I play like I have always played(I pull hard). Also I can hear a clicking noise when I fret the string. Do you think my pickups are too close to the strings? Should I lower the pickups or raise up the strings? I have used flats in the past and don't remember if I had that noise with them? I have emgs on my '87 g&l SB1.
