just go to the lady's aisle in the supermarket or wherever and get a emery board that women use to file their nails and just score around the top...you don't have to score it heavy, just a few scrapes around and hold the amp in one hand and use a towel or cloth around the tip you scored and just "snap" it really quick..should come right off..the towel is so you don't cut your fingers if it "breaks"...after you do a few you'll get the hang of it..
