Epiphone 57 reissue

[Epi95]

So, I got my epiphone 57 reissue Les Paul through craigslist about a year ago. He replaced the pick up (p-100) to a p-90. All was well and the guitar sounded really nice until just last month. I started to notice that the guitar was starting to sound muddy. I usually have it on distortion, and it's just not coming out as punchy as it used to. It had also been to the shop before it got muddy because of a veiled wire on the inside. It sounded great when i brought it home and I have changed the strings a couple of times but I don't think that that's what would be making it sound dull. I also contacted the guy from craigslist and he said the pick ups are only four years old. Can anybody help me resolve this problem?

Pick ups need to be set up like anything else on a guitar.

 

If you've changed strings perhaps the bridge is higher now than it was (strings further away from pick ups - higher action), this is probably the main cause of mud in a guitar that once sounded fine.
