The legend never dies. These are mythical scratch cartridges. From Q-Burt to Z-Trip, they have been used at least a few times to light up the house with the Tech's attached. I have been a DJ and hobbiest for 15 years, have taught turn tableism at Sam Ash in KOP Pa, and have competed in DMC San Antonio 2010 under a different DJ name and took 27th over all which is ok with me, but far from perfect. Right now my shop is closed up but I am getting back into the groove of things and ready to DJ again and again. I never leave for a gig without these in case there will be a throw down of DJ skills to pay da bills. I know that other DJ's have talked trash to me before about being a rapper and DJ but so was Dre when he started and now look at him. These DJ tools will allow you to get the respect and gain the skills you want from the anti skip tech which comes stock in all Shure cartridges and stylus's. They kick @$$ hands down and the name speaks for itself. Get these while they still make them. And somebody call Panasonic and say YOU NEED TO PUT TECHNICS 1200 & 1210 BACK INTO PRODUCTION!!!! WE NEED THE QUALITY BROUGHT BACK. Thanks again Shure for being totally Shure about providing a great DJ tool to remain an immortal legend handled by mortals. I love these joints and so do the other real DJ enthusiast out there. Sincerely,
