Looks like HB got a job lot on jazz knobs - they are on everything - P/PJ/Jazz/mustang. Also noted the neck nut widths, all 38mm (jazz) on P/PJ/Jazz, must have a job lot on those too.
Like the truss rod wheel, though it should be within the neck, not the body, as now customising the pickguard (without a cut out) is gonna be problematic, having to remove the pickguard each time a truss rod adjustment is required. Not too bad for a jazz, but a real pain for P or PJ's.
Like the natural PJ, shame it's not in stand alone P version.
Where did the Gotoh tuners all go???
