I'm ordering a Schecter Stiletto Stealth-4 Bass. The stock pickups are a Schecter Diamond P in the neck position and a Schecter SuperRock MM pickup in the bridge. Are these any good, or should I think about upgrading to something else in the future (like EMGs, which normally come in Schecter guitars/basses). Please don't try to talk me out of ordering this. I just want opinions on the pickups.
