After searching around for a while and not finding much, I was hoping you guys could answer a real quick question for me. If was to put a picture or a playing card underneath the pickguard, would it be potentially damaging to the finish if I took off the pickguard again? I vaguely remember someone mentioning that a bassist has done this in the past with a playing card (the name escapes me at the moment) but couldn't find that post for the life of me. I'm mostly concerned because I live in a fairly humid area and I've seen how easily they can cause problems when they're stacked for prolonged times. Probably an easy answer for somebody, I just don't know enough about the finish of the bass to say one way or another. By the way, it's a black finished Fender Jazz if that matters for anything. Thanks for everyone's help!
