What years and models have the "rounded 50's neck?" In searching this site and the web..there seems to be some conflicting info out there..some folks say pre-2013 standards...some say late 90's...? Some say early 61 reissues...? Even Gibson's own site pages can show some models as having an "oversize rounded" neck and a "fast slim taper" for the same guitar at times... I know I'll never get a truly fat neck unless I get a SG Classic but what traditional humbucker equipped model should I be seeking if I want a bigger more rounded neck? I am allergic to anything that is too flat in the back..
