Guitar center had Schecter Stiletto's for like an extra $200+ off their usual prices this weekend. After going back and forth between a couple of Ibanez's and the Studio 5, the Schecter's smooth play style and sex appeal lured me in. I am not totally sold on the pickups however. They have a bit of hiss from the treble, and the low end lacks clarity.. I am wondering if there are pickups that I can just drop in to replace these? They are passive pickups (EMG HZ) but the bass has a built in pre-amp. Am I able to put active pickups in with the existing pre-amp or do I have to put in passive pickups? I am on the fence as to whether to take it back to GC or just learn to live with it for now with the hope of replacing them.
