So since I've been doing my own guitar wiring for the past year or so (badly and sometimes successfully) I was curious about one thing in particular. even if you ground your guitar PERFECTLY, you can turn your guitar up really loud or add some gain, and it will buzz until you touch the strings (even the guitars I've had professionally wired ) A little bit after as well. What's the "scientific" explanation behind this? I've figured because humans are like a giant saline solution, therefore we're really good conductors and offer a better ground than our volume pots/input jack. Can anyone offer an explanation?
