One last thought: does the pickup have alnico slugs or a ceramic bar and steel slugs? If the slugs under the e string have lost their magnetism, if alnico, or if they may not have good contact with the bar magnet underneath the pickup, then this will happen. I had a Pickup that had bar magnet and steel slugs in another guitar. The bar magnet cracked. The half that retained good contact with the steel poles sounded fine on half the strings, and the other half of the magnet that did not retain good contact with the steel poles sounded weak on the other half of the strings until I pulled the pickup apart and rebuilt the magnet.
[/quote] I would guess that that was because the field was disrupted. The slugs dont actually need to contact the magnet or so I've been led to believe. .
