I have an old ā55 Precision with a single coil Seymour Duncan. Now this was done 20 years ago and I forget all the details, however it has that hum. Iām thinking start with shielding and see how that goes and if still there replace the pup, maybe a Lindy Fralin ā51 which supposedly would drop right in. Any one here have any suggestions for a better procedure or parts? Thanks
As you probably know, the pickup itself does not generate the hum, it derives from external sources. I can usually just turn 90 degrees or so, and find a physical position where the hum goes away. If it's there ALL the time, then most likely a grounding issue.
