yeah Ive done it before
WHEN I WAS LIKE 12
and didnt know any better.
If it still has the orginal heads on the bottom you will probly not like the sound that they make at all, I would say that it is going to be kinda high pitched and not going to get a real good sound out of them at all.
also I would ask that guy if he would flip his snare oer and start playing on that head as well
If you do that you are just going to end up replacing twice as many heads real soon.
