I would say take a hard look at the Epi Lucille. Much will depend on how loud and how much gain you play with. Semi Hollows are prone to howling due to the "hollow" chambers in them. This is ONLY a problem when you play with both High volume and High gain. It can be eliminated in a few ways. Use a Long enough chord to get far enough awaay from the Amp to avoid it, or Wax Pot the PUPS.
The Epi Lucille although it is a Semi Hollow guitar does not have "F" holes therfore the feedback issue are virtually non existant. The second reason these are real nice is if you plan on replacing the PUPS or Pots etc. They have a rear access cavity to get at all this. A Conventional Semi hollow guitar you have to work thru the "F" holes and that can really try your patience.
