Is the pickupcover removable on the 4001v63 and the 4001CS horseshoe pups? Some say it is and some say it isn´t. So, whos right? I´ve read somewhere that on the reissue horseshuepup the magnet doesn´t go round the strings like on the originals and therefore it is possible to remove the covers. I´d like to know this before I consider buying a used 4001v63 I have my eyes on.
