I need to replace the pickup selector switch on my Gretsch GT5435T. I just received the replacement switch. It's a Gretsch SKU (0074895000). Not a Switchcraft. One of my least expensive but one of my most fav's to play. I've never done this type of repair before. So looking for some help. Suggestions, tips, procedure list anything that can point me in the right direction on how to properly do a switch replacement on a Gretsch Jet. Thanks, Joe
