I play a PB5 with the bridge J pickup on country gigs (and Top40 gigs). P pickup at 100%, J around 75%. Active Mode, Trebel at 0, Bass at 6, tone at 50%. Works for me. Great thing is I don’t need to mess with Amp EQ to get my tone. It’s all on the bass.
I do think the Carvin pickups are a tad tinny for my taste, but the EQ helps a lot, and they’re just as bad as Fender pickups IMO.
Overall, the PB5 is a fantastic working bass that I’d purchase again. Wish more companies would make a reasonably priced active/passive PJ 5 string. They really work for every gig.
