I'm posting what I just posted on The Gear Page.
I installed a couple Seymour Duncan pickups in my Epiphone LP, and now the guitar sounds like absolute ****. I put the SDs in, didn't like the sound, tried re-wiring, still didn't like it, but the stock Epiphone pickups in - much better - then put the SDs in one more time. Still sounds like ****.
I have a Seth Lover humbucker in the bridge and a Phat Cat P90 in the neck. First off, the Seth Lover doesn't balance well with the Phat Cat at all - the Phat Cat is much, much louder. Second, now when I play clean, my tone is muffled and muddy. Third, when I play dirty, it's so grainy and abrasive that I can barely stand to listen to myself play anymore.
Any advice on how to make this work? I'm about ready to give up...
