Sorry - I didn't mean to include "heads" in my postDOH I got carried away with the list of Pre-Aged drum stuff. Maybe I should have been specific and just said pre-aged drum shells and sticks. I am seeing lots of pre-aged stuff around though.
Like I said, if I were to do it, it would be aging so subtle that you would just think it's another old, well-taken care of drum kit. I wouldn't purposely rust out hoops or anything like that. However, I wouldn't be above aging a coated reso kick drum head or anything like that.
