I've had a Sheraton for years now, early 90s and it was second hand then. The original pickups were very microphonic and fed back a lot so I changed them out and it made a huge difference. I don't know about the latest Epiphone pickups but maybe they've improved?
Yhe guitar itself is absolutely fine. Not the same as a Gibson 335 by any means but for the price it is excellent.
