My EC Strat's Lace Sensors (all gold) are definitely noisy when I face my amp. They are fine when I stand a few feet away.
All pups will act as an antenna for 120 cycle signal. Put your guitar near a computer and see how bad it gets. Lace makes thier pickups so that they are shielded from 60 cycle. It's not perfect, but it's nearly impossible to eliminate ALL interference. The closer you are to any electromagnetic field (like your amp generates) the worse it is. Loosing that noise when you are only a few feet away is actually pretty good. BTW, Nice Strat! I have golds in two of my strats and I really like em, and compared to the pups they replaced, they are "noiseless"
Perfect? no, but pretty damn good. They hum less than the burstbuckers in my LP.
If you want really quiet, try the alumitones. The deathbuckers I recently got are VERY quiet. I think I am only hearing noise from the cable and amp with those. I'm really impressed.
