suddenly a few days ago my goth epi explorer started too sound really muddy and fuzzy and lost all its cut. i tried other guitars on my amps and they sounded fine. any ideas on whats wrong/what i should do

That sounds more like a pedal/amp issue...which is why it's strange that you say it sounds fine with other guitars. On the whole, guitars don't have various states of repair - they either work, or don't (or occasionally work, but with lots of noise).

Unless you're using active pickups, I suspect your problem is elsewhere - or else your ear for tone has suddenly improved!

Surefire way to rule out anything else is to try it through another amp.
Tastes like chicken, if chicken was a candy.
