Im playing a mexi strat into a marshall avt50 and was looking for ways to "supe" up my guitar. I decided to drop new pickups in, and have no clue what to choose. I play more or less satriani/evh kinds of music, but have no idea what pickups to get. I figure humbuckers are out of the question b/c i dont wanna take a router to the body. Any suggestions?
