    I have a Carvin active bass...the jack was messed up and making weird noises with my cable, so I replaced it about a month ago...with the wrong type. I purchased the exact same one finally finding it, it's an older style switchcraft, and triple checked my old wiring diagram with my new stuff I did tonight.

    Some reason, whenever I roll the mids up, there is the dreaded 60 cycle hum. Both pickups are balanced evenly on the blend pot.

    Before this was not an issue. It's the Carvin 8v preamp, 3 band, with brand new Bill Lawrence Jazz pickups aka Wilde pickups.

    Any help on this? :ninja:
