This is my first post. Hope you can help me out. I have a pretty bad case of the dreaded 60 cycle hum. My '74 Strat has been this way for the 30 years I've owned it. I had it completely shielded and re-wired by a very well-known repair guy here in San Francisco. But it still buzzed so I put it under my bed for literally 20 years. I just took it out yesterday and the buzz..still there. Took it back to the same guy and his analysis...not grounding and not shielding. He thinks it's a pickup problem. Since all three pickups have the same buzz it either has to be 3 bad pickups or something else. It's a decent guitar but I've played better. And it needs a refret. I'm not ready to put $500 into it for fret work and a set of nice pickups. Any thoughts by you more technically minded guys on what might be the problem? It has sentimental value so I'm not ready to part with it but I can't play it either.
