Sire V7 5 string v2 with EMG J5 replacement

[BrutalPigeon]

Hello,

did anybody tried to replace the original pickups with active EMG J5 while keeping the original preamp?
I am not really an expert on bass electronics, so i'm not really sure if it can be done.

Thanks in advance for answers!
Cheers.

certainly can be done, the biggest question isn't electronics, it's whether the new pickups fit the existing routes.

hmmm, I just did some measurements. Sire J pickups are not standard J pickup dimensions. That is a bummer

not standard J pickup dimensions

Study Fender history - there's no such thing as a "standard", they've been all over the place over time, especially when you include Squiers, MIMs, MICs, and MIJs.

I was wondering if the active EMGs might require different pot values than the passive Sire pickups. I guess it will depend upon whether the pickups are wired directly to the preamp, or directly to the pickup balance pot.
I wouldn't be surprised if it's the latter, which might require a stacked balance pot of a different value for the active EMGs.
Routes can be opened up a little more easily enough.
I've seen people load the J-System into their V-5s.
