I think you'd probably be getting the best of the deal in that trade. Does your Ibanez have a hard case? Does the Epiphone come with a hard case? I personally like both. I'm not much of a tremolo guy though, usually you break a string and the whole guitar goes out of tune which makes changing strings an olympic sport when playing live but thats just my opinion although I have never used a Bigsby.......... EDIT: Oh also, switching out pickups or even fixing the electronics in a Hollow Body like these takes the dexterity and patience of a grade "B" superhero. All the work has to be done through the f-holes. Real tricky, unless you are a guitar tech or know one...........
