Sorry to be making so many posts in my first week on the forum, but I had another quick question for all you experts out there.
Is it normal for a guitar to buzz and hum until you touch a metal part like the strings or bridge? I've tried checking around online but I have found people saying both that it's normal, and that it's NOT normal, and I'm really not clear on which is the true answer.
It seems to me that if everything is grounded properly internally, all of that humming and buzzing should be going down the ground side of your cable and out the ground on your amp; right?
I just shielded my strat and it is significantly quieter than it was before, so I thought I'd done it all properly, however I still get some buzzing until I touch the metal.
Could this be an issue with the grounding in my amp? I don't have another to try out, so is there a way I can check that?

its not normal at all. it maens that your strings are not grounded.
(kuzi, I think you mis-read marco's question, didn't you? )
Yes, it is normal, albeit undesirable, that guitars hum and/or buzz when plugged into an amp. It's also normal that when you touch the strings of a guitar, it should quiet down considerably or completely. Shielding the guitar (per the "Quieting the Beast" article) goes a long way towards making this normal behavior less intrusive to our ears during those times when we aren't pounding on the strings. As you already know.

Simply use a multimeter to test for continuity between the output jack's mounting plate, and the bridge/strings. If the meter doesn't read 0Ω, then you've got a problem. In such cases, go a step further, like so: Plug a cable into the jack.... now check for continuity between the tip of the cable's free end and the strings. If you got 0Ω, Bingo! you know the wires to the jack are reversed. But if you got "OL" (what most meters display for an open connection), then the strings simply aren't connected to anything. (If the reading is really high, but not infinite, then it might be a bad solder joint somewhere along the line.)
In any case, you should now be able to locate and correct the deficiency, right? ;D
