Sadly i discovered when i finally plugged the Guitar in that the fault was not eliminated by PRS. They stated they cut back the (Output)Wire and re-soldered it.
Unfortunately they only cut out one piece but the cable was obviously broken on 2 parts. So after having issues with crackles, knock and touch sensitivity of the cable again i cut out the faulty part by myself and bridged it. One of the next days i have to exchange the whole cable, not gonna send it in for another nearly 7 weeks....................................
