Agh, look what I've done
Sorry I asked. I did a search earlier and only found a mention of the vibration mechanism on the 4/4s causing a sound, but figured that was not the case here. Anyways thanks for clearing it up. For the record, my 5 didn't have this issue, and I wanted to make sure my $900+ didn't come up with a problem. I'll go hide in a hole now..
