This is the best endpin jack available today. We use this one on nearly all of our Folkcraft and FolkRoots dulcimers, as well as on our Druid Moon ukuleles. Switchcraft endpin jacks require a threaded hole for installation (we sell the required tap separately). After soldering the pickup wires to the jack, you then screw the jack into the threaded hole in the end of your instrument - no visible screws, and a great look. (And Switchcraft quality, so reliability won't be an issue down the road!)
Technical specifications:
Required hole size (before tapping for threads): 1/2"
Tap size (use the tap after the 1/2" hole is drilled): 9/16" - 12
Number of conductors: 3 (you can use either two or three, depending on your pickup)
Wiring hookup:
There are three soldering lugs. Use the silver-colored lug on the outside for your ground connection. (the braided wire on the L.R. Baggs pickups that we sell). Use the smallest (copper colored, center) wire for your "active" or "hot" connection. (the inside wire on our Baggs pickups).
If your pickup has a balanced output, you'll still solder the ground on the outside (silver colored) lug, but you'll use both of the center (copper colored) lugs for your pickup output wires.
If you are trying to visualize/correlate the three soldering lugs to a 1/4" guitar cord, the "tip" of the cord is the shortest lug, and the "sleeve" of the cord is the longest lug. If you're using a 3 conductor (stereo) cable, the "tip" is the shortest lug, the "ring" is the medium-length lug, and the "sleeve" is the longest lug.
