A little off topic but it follows on from a previous post...

I previously had complained about a hissing/buzzing sounds through headphones which i thought was the USB, the headphones, the lead, pretty much everything but now i realise the problem is my pickups. I have a Fender Strat and the pickup noise is quite noticable. I am sitting at my computer so theres the usual array of electrical equipment around me. I notice if i spin around 180 degrees and face away from it all the noise is significantly less, although its unworkable given i have to find the sweet spot.

Is there anything i can do? i have standard Fender Mexican pickups - are they rubbish?
