I showed my Classic S to my friend (a guy who builds his own tele's) and he said that the cause may be that I'm missing some kind of "copper lining" in the switch plate cavity???

Also, ironically, I was scrolling down the G&L Discussions Page and found this http://guitarsbyleo.com/FORUM/viewtopic.php?f=13&t=1650 <-- I dunno if one of those problems may be my problem...

But seriously - I haven't a clue as to where the feedback problem is... my guitar, amp, or pedals?!?!... Any help would greatly be appreciated!!!
