G&L JB-2 input jack problems

    My new (to me) JB-2 has a serious input jack issue - would love help!


    Played it for over two hours today to get to know it...and the bass completely started cutting out. Took me a while to figure it out, but the input jack (inside connection) is loose. I can make the bass cut out just by moving the cable input slightly. I opened the back, and the input jack is a closed jack (meaning the cable end does not protrude into the control cavity. So I have nothing to "bend" into place or tighten...I'm at a loss on how to correct this.

    Unfortunately, I can't play out with it if it cuts out whenever the cable input moves.

    open it up and see if all the wires are soldered correctly....maybe the wiggled out of place and junk... thats teh first thing id do
  3. wires are soldered fine - the jack has the contacts coming out of a "wax" end that encloses the 1/4" cable end. The problem is inside the jack - the cable end is loose and can wobble.
