If you get one of those Fisman pups, spend the extra and get the humbucker model. I have the single coil and, though it sounds good, it buzzes like crazy.
I don't think you need the preamp booster if you're already getting the acoustic modeler. IDK, I might be wrong here.
Try-before-you-buy with generic PAs. Some are pretty good, others hiss like nobody's business. A lot of the cheaper package deals are barely loud enough to do anything.
