I have a relatively new G&L L2000. If I use a Fender cable, the signal shorts out occasionally. The cable plug is semi-loose in the jack. If I use a different cable, the plug is tight with no signal issues. So is it really the Switchcraft jack, or is it that some manufactured "supposed" 1/4" plugs are a little smaller, and not a good match with Switchcraft? I seem to recall this issue, from many years back, dealing with Hamer guitars and basses, which used the same jack.
