I contacted my dealer to get an updated cable slide/guard for my Xcentric 7. Instead of taking my order, he suggested I “tune the ATR”. This is new to me and I’ve never heard of anyone doing this before. To be honest I think there was a misunderstanding over the phone. He told me to loosen the riser bolts and twist the tip of the ATR and it will eliminate my string issues. Anyone have any history or experience with doing this?
