I have a stock / original ‘91 Gibson Thunderbird that has 60 Hz hum like a Jazz Bass with two bridge pickups.
It’s shielded to death with conductive paint AND aluminum shielding tape in the control cavity and the pickup cavities. Everything is grounded and has been checked with a meter to verify good continuity.
The internet says the original ‘91 TBirds have “humbuckers” in both neck & bridge positions. I have my doubts about that. Either one of the pickups turned on, or both on
and it hums to high heaven.
The wires from both pickups are single conductor with a shield, and both the shield and the single conductor make up the electrical connection to the pickups. The wire goes into an epoxy glue filled back about of the pickups so there’s no way to visually confirm anything with the pickups.
I’m tempted to wrap both pickups in aluminum foil to see if it helps, but it would probably keep them from picking up the string vibration and they would probably still hum…
Anyone have any info on ‘91 Tbird pickups? Are they really single coils?
It wouldn’t be the first time. I also have a Gretch Electromatic 220 that the manufacturer claimed for 10 years had humbuckers & then @LowEndLobster discovered otherwise.
