I switched my Ibanez RG2570's original Dimarzio/IBZ pickups out for this set and the difference is like night and day. These pickups provided a bit more gain which suits the kind of music i play and for an incredible price. They just sound alot better, this is of course a matter of taste.
Worth noting:
1. I bought regular humbuckers despite the trembucker bridge pickup being a better fit, i have no noticable sound level differences.
2. The pickups did require some modification to the guitar to fit the protruding adjustable pole pieces on the under side of the pickups and also to the fastening wings of the pickups.
