Good to hear that it was the simple thing.
Now the tweaking comes...play with the hight of the PU (and maybe even carefully the pole pieces) and be amazed how much that changes your sound. You can do a lot of tweaking there. After that of course your amp setting will need one or two as well, but take time to get used to the PU and fiddle with it.
When I got my aftermath I had to to have it go way down and raise the pole pieces closer the bridge up on the lower 3 strings. World of difference in sound
