Re: Some odd problem...
Well you say feedback, and you say buzzing, which are two completely different things, so let's start with feedback.
To kill feedback, first try stepping away from the speakers. Then try turning down the gain. If that solves it, crank it and roll with it. If it doesn't then you might have a microphonic tube in the amp, or pickup in the guitar. I am being very vague and sterotypical here because I'm a lazy writer.
To kill buzz, get humbuckers, and make sure the guitar is properly grounded. If you can take off the cover and touch the wood (I'm assuming there is electrically active paint in this guitar) and it sounds quieter than when you touch the strings, then I'd check that the wire from the bridge to the ground is in tact.
hope that helps, and I'm sure someone else will come along with more info for ya.
