These are the pickups in my new Plus Top Pro, correct? How they compare with Burstbuckers and Classic 57's? Are the good enough to where you'd keep them even if you had planned to upgrade everything else, as many do? Now I have no reference point to the questions as I've never plats with Burstbuckers or 57's. As to the Probuckers like in my LP, I like how they perform. I notice that articulation seems to be better than some of the stock pups they'd been using on many models before. The B and low E string shine through more prominently and hold their own instead of sort of getting lost. Again though, I don't know how they compare to Gibson/Epiphone's "better" pickups.
