Hi! I wanted to buy the Ibanez RKB900... now that I have the money it's been discontinued!!! so, I just saw a Fender MIM jazz bass standard... beautiful!!! and really cheap... I'm thinkin' in buyin' it and then install on it seymour duncan passive basslines pickups and the leo quan badass II bridge.... so, my question is... will this changes improve a lot the sound of the MIM jazz bass???? should I go for it??? should I leave my bass with the original pickups and bridge?? what's your advice??? THANK U!!!
