Although it's been said, many times, many ways, my amp's buzzing!

ok... I know, I know, "not another topic about buzzing!" but I'm sorry. it's just that when I turn on the overdrive, and crank the gain, it has an unnoticable buzz at low volumes, but when the volume is cranked, there is a very loud buzzing noise, when I place my fingers on the strings the buzzing reduces some, but not all the way. now my guitar is set up s/s/h and when I have a single coil selected, the hum is much worse, and when I have my humbucker selected, it's not as bad, but still bad enough to annoy the hell out of me and anyone listening to me... now, this is a pretty cheap guitar and amp, but I was wondering if maybe it was just because my guitar has crappy pickups, and that if I replace the humbucker (which is the pickup I'm playing through 90% of the time), it should fix the problem, or if it is the amp, which is about a $50 solid state... I'm real sorry about having another topic about this, but it's important to me... cause I don't want to throw down a bunch of money on a new amp, if all I needed to do was replace a pickup... thanks for your help in advance

You know... I did that, like right after starting this thread, I guess I should've done it before... lol. that guitar nuts thing inspired me to go take apart my guitar... lol. this sheilding technique sound like it would add up to costing a lot though, and the guitar itself only cost $140, so I'm deciding if it would be worth it...

If the buzzing is not as loud when you touch the strings, there's probably a short somewhere in the wiring of the guitar.....as for the single coil pickup buzzing louder than the other pickups, it alway's will. The humbuckers are 2 single coils put together that cancel the hum, that's why they call them humbuckers. There will alway's be some extra noise the louder you crank an amp with overdrive, a noise gate may help some.
