alright...so i'm wondering if dimarzio ultra jazz pickups will fit into my fender mia jazz bass without having to do any body modifications. i know some of the mia jazz basses have a wider bridge pickup, and i think mine does too. like i said...i think. it's kind of tough to tell (i haven't really checked it out, but i think it's just alittle wider). did dimarzio compensate for that? basically...are the ultra jazz pickups a direct replacement for my j bass?
