Installing Active Pickups

Are you sure they are active pickups? I went to dragonfire's site and I could only find 2 kinds of bass pickups. A P and a J set, neither of which were active.

If it was one of those, then yes you should be able to use any active preamp with them.

True active pickups are gold MECs or most EMGs. The difference is that they require power to operate the pickup itself. Most basses that are said to have active electronics have a battery-powered on-board preamp wired to regular passive pickups. Any of these pickups in such a bass can be run passively as well.

If they really are active pickups, then you will at the very least need to change the volume pots. Active pickups usually use 25k pots (and I think I've seen some with 50k). Passive pickups tend to use 250k or 500k. As for the tone controls, I think those will be fine (I recently built a bass using an EMG control set with active pickups, but the controls were said to work with both active and passive pickups.)

 

Frostymoose,

Thanks for the insight. I play bass. I don't do electronics. I have a 1990 Ibanez SR800 P-J configuration. There are Bartolini and Carvin pups. It looks like the battery was added after market. It's in the space with the pots. There are solder changes all over the place. I thought this had active pickups but I'm thinking it just has the preamp.

What do I need to look for to figure out what I have? The volume of this bass is 25% less than my Epiphone bass but I really like the tone it generates. I've replace the battery.

 

hi! is the bartolini p-up,the one that sounds les than the epi p-up or the carvin?my guess is is that the carvin isn't an active p-up!also the activ soundgears have and separete battery casing on the back! hope it helps!

 

That bass has passive pups and an active eq system. The chip in the eq was fried. I replace the full eq harness and pots but kept the pups. The bass now plays beautifully and is powerful.
