OK, the jack on my Kubicki has been acting up. The problem with the though-body jacks is their enclosed case. You can't tighten up the plug clip when it gets stretched. I like using them, but they do wear out. Of course, I decided to check it out and several fun things appear. First, the electronics, ala NASA, are crammed into the cavity with zero tolerance. I had to remove all of the circuitry guts just to get at the bottom of the jack. The guess what, one of the jack wires broke off the circuit board (a tad brittle after 20+ years). Not a big deal, just annoying.
So, I ordered a new through-body stereo jack. It needed it anyway. When it arrives, I'll be back asking for pointers on wiring my first ever stereo jack. I'll probably go with new wires for the jack to circuit board run.
The biggest pisser about this is I was going to take it to practice tomorrow. Oh well!
