this morning, as i gave my room a much needed cleaning, i took a look at my superkick 2 and all the good memories we had together. you see, it was not too long ago that my good friend ended up cracking on the top ply. now when i realized i had cracked it, i remember i was not feeling as if my pedals were rebounding off the head like usual. now, i have one ply head on there that i had lying around. ever since then i haven't felt like my beaters are rebounding from the head enough. the pedals seem to lag now no matter what kind of spring tension is applied. i was wondering if the difference in plies makes a difference or is my tuning the case.
