Switchcraft jack sockets
Simply the best you can fit
As a rough guide, a short thread socket is fine for Strats, most Teles and applications where you only go through a scratch plate or control plate. Order a long thread version to go through a significant thickness of wood … as in some semi acoustics. If in doubt, a ‘long’ socket will work fine in place of a short one, however the reverse is not the case.
