to be honest with u, imo as a last resort i'll change the pickups.
i would even recommend investing in pedals to achieve the tone u're looking for rather than changing the pickups. even if u changed the pickups to the high output pickups of ur choice, u play through a poor amp(i'm not assuming u have a poor amp) or without quality pedals u'll still sound crappy.
i can use the same guitar with stock pickups and, with a decent amp and a decent rig, i can achieve what i'm looking for. a pickup swap isnt always the remedy for good tone. there's nothing embarrasing abt telling ppl ur pickups are stock. really.
ritchie blackmore kept his fenders stock. randy rhoads gibson custom had stock pickups too.
