well you hear tapping.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif there are lots of ways to get tinsel slaps:
1. cloth on the cone isn't placed correctly.
2. tensil lead too long
3. and some more ways..
to fix number 2 problem, fold the lead to its shaped like an "L". that should work. if not, then you'll need to cut it shorter and resolder the lead together again. if problem number 1 occurs, just place the cloth at the right place (where the lead is slapping the cone). if the cloth is too small, take it out and get a bigger cloth (if possible).
