I love my 74 P- Bass! It is all original with virgin solder connections and everything! It plays and sounds amazing. However, I want to convert it to an active P Bass. Here is my plan: I want to unscrew the pups from the body, and remove the ground connection from under the bridge so that I can remove the entire pick guard with pots, and pups, and solder points all untouched. I want to get a new pick guard, new pups, and and an active pre to drop in. Essentially, I would like to have 2 systems...an active system and the original passive system attached to 2 different pick guards. Does this make sense? Has anyone tried this? What pre-amp is best? I would like something with active mid, bass, and treble controls! Thank u in advance for advice/ suggestions/ reviews!!
