PAXPHIL LJ20 CR Flush-Mount Cylinder Output Jack, Chrome
The PAXPHIL LJ20 CR is a flush-mount cylinder jack for a 1/4" (6.35 mm) plug that screws into a guitar or bass body. Its knurled flange sits flush with the surface, so the jack does not stick out and needs no separate plate. The design is modular with 3 contacts and a large solder terminal. The body is 40 mm long, 55 mm overall with contacts. The chrome finish suits most instruments.

Flush Mounting, No Plate
The jack screws straight into the body hole, and the knurled flange stays flush with the surface. The cable goes in neatly with nothing protruding or snagging — a solution often found on basses and modern electric guitars.
3 Contacts for Active Circuits
As JAM explains, the third contact switches on power to active electronics only when a plug is inserted, so the battery does not drain while the instrument is unplugged. That makes the LJ20 CR a logical replacement on a bass with an active preamp; in a passive circuit the third contact can be left unused.
Dimensions and Large Terminal
The jack body is 40 mm long, and the contacts add about 10 mm more — 55 mm in total. Check these figures against the depth of the body hole; the large terminal is easy to solder even with thicker wire.
