    Hi Guys,
    I just bought a 1978 Jetglo 4001... but the action is sitting a bit too high for my tastes.
    Can someone here give me some advice as to what would be the safest way to go about adjusting this at home? Im not saying that I am going to at this point :)
    I know its more of a challenge to get it right without popping off the fretboard, and I have minimal expeirience with making adjustments. But I am curious as to how some of you go about doing it yourself (if any of you do).
    Meaning ... How much to tweak the rod initially, or how do you apply the pressure to the neck and make the adjustment .... things like that.
    any comments are welcome
    thanks
    - Tom

    BTW, this was sent to me from a Friend, its from John Hall CEO of RIC

    "Old-style rods are a whole different story in themselves - doing
    them wrong can cause the fingerboard to separate from the neck
    down by the nut."***
    "This is absolutely true and for the most simple of reasons.* The
    old style truss rod requires that the person doing the adjustment
    pushes the neck into position and only THEN turns the truss rods
    to snug up the tension to hold that setting. The old rods were not
    designed to actually move the neck only hold it in place
    after manually moving it. When tightened without releasing
    pressure from moving the neck, most of the energy of the rods is
    directed to popping off the fingerboard. It's a good system when
    you know how to use it, but unfortunately many people didn't
    understand it."

    Hi, Thanks for your help ... Like I said I really dont know too much about this.... But where should I measure from.
    Meaning Should I measure the "E" string height at the 12th fret or does it not matter.

    Hi, As far as I can tell its about a single card away from the fretboard holding the string how you described....
