I am currently useing dimarzio ultra jazz 5's on my mexican fender jazz bass. i had to re route the bass so that the 2 new (smaller) pickups fit. and i heard nordstrand finally came out with a split coil jazz 5 set. i'm likeing my dimazio's, but i just wanna know if it is worth spending the money (around 500) to buy the nordstrand set, probobly a new routeing job, a wireing job and possibly a new pickguard. worth it? does anyone know how the diffrence would be tonally? i'm currently playing rock music, and i'm looking for a growlly agressive tone. thanx!
