I can't picture what you mean. From my mental picture, a straight plug would have to hang the cable down straighter (down from the guitar), no? An angle plug would flatten the angle more parallel to the floor (back from the guitar), wouldn't it? I am not questioning the validity - I literally don't understand the reasoning. I started on Tele's and so have always just used a straight plug, whether on a Tele, Jazzmaster or LP. The issue never occurred to me until I saw it pop up frequently on this forum.
