So i'm in the process of building a dream (to me ) bass. I'm taking a beat up MIJ Fender P Bass and putting in a Dimarzio Split P and a second P in te bridge position (ala the Blacktop Series Jazz Fender makes) I already figured I'm going to add a couple switched or push/pull pots for series/paralell but now I am trying to figure out the best onboard preamp to pair it with. 3-hole, 5 hole, whatever, i really dont care. It's a frankenbass that will have no resale value so I dont care about how many knobs it has. What I do want is 3 (B,M,T) or 4 ( B,LM,HM,T) band eq, active/ passive with passive tone and individual volume knobs. My goal here is to make a bass that is extremely versatile. Split P in Paralell giving a Soapbar style tone, In series giving a modern-traditional P bass tone. EQ to taste. I also hear these pickups are EXTREMELY hot output so perhaps I should scrap the idea of onboard preamp altogether? Would love to hear some opinions! Thanks y'all!
