False overtones?

[buduranus2]

Lately I've noticed false overtones from the high E string on my Gibson Firebird when connected to an amplifier. I've changed the bridge and changed the string, yet the problem persists. (It's not noticeable acoustically, though.) I've lowered the pickups and that didn't help either. Intonation on the bridge is good. I'm really perplexed. Any ideas?

Pickup mounting spring?

If the false overtone is not audible unplugged then it can only come from something later in the sound chain. Does it appear on all notes on the high e string or only on some?

Assuming it is after the signal conversion to electric voltage, i.e. everything after the pickup could be the culprit. Start by:

- checking the solder connections in the guitar, in particular the connections to the switch and the pots and to the output jack. Also make sure that all the ground connections are good. Tug the wires gently and see if any of them come loose. Resolder if necessary.

- checking the cable connection between the guitar and the amp.

BTW: does this appear only with that particular guitar or also with other guitars? Does this appear only with one amp or with several amps?
