I prefer to pick near the neck (on top of the neck pickup), but whenever I alternate pick fast, my wrist scratches the three lowest strings, creating a muffled sound, where it sounds like I'm playing a muffled open chord while alternative picking at the same time. It feels more natural picking near the neck, than the middle of the bridge, and the bottom of the neck seems to produce a cleaner and more isolated staccato than picking in the middle or bottom of the bridge.
Keep in mind, that I'm not referring to the pickup selector, but my hand placement.
