Hello, The little preamp-like "bass boost" thing on my only bass has freaked out, sending all sorts of knocking and squealing sounds to the amp. There is no sound at all with the battery out, and no active/passive switch. I am handy with a soldering iron, so I am going to switch it to passive so that I don't have to deal with this any longer. However, I don't know if I will need new pickups or if the ones in this bass would do. I can get others if that is required, no problem. This is the creature here: Squier® Vintage Modified Jaguar® Bass Special, Rosewood Fingerboard, Crimson Red Transparent | Squier Bass Guitars I am assuming that these pickups are underwound for passive use, since that would save some money on construction, but if all I gotta do is remove the bass boost from the circuit that is what I will do. Many thanks for any help you can give!
