Truss Rod Adjustment: Does it matter which end of the neck?

    I'm considering purchasing a Fender 60s Classic Jazz Bass, but I have a question regarding the truss rod adjustment. Should I count it as a negative that this bass has the adjustment at the body end of the neck?

    I currently have a Mexican Standard P-Bass, which I enjoy. It seems though that with temperature changes, the truss rod loosens up, so I wind up adjusting every few weeks. I live in a cold climate so my bass sees lots of temperature changes. Do I just have a badly made instrument?

    Will I regret buying the Jazz bass because I'm going to have to keep taking it apart for truss rod adjustments? What do y'all think?

    I prefer trussrod setting on the body side because it's easier to adjust but I wouldn't want to be bothered with taking the bass apart every time it needs adjustement.
    If it doesn't have a nicey groove so you can insert a key, I either pass or make one.

    I would count it a negative to have to remove (or loosen) the neck to make a simple truss rod adjustment. Thats a huge deal that you will live with long after the "coolness?" of the 60s classic wears off. The newer USA made models adjust from the body end too, but that rounded allen truss tool is likely the most versatile update Fender ever made to a J/P bass.

    As far as your Mexi-P and frequent truss adjusts, I don't think you have a "badly made instrument" and the older it gets, the more stable I think it will become. Thats been my experience.

    Actually most luthiers state that the adjustment at the body end of the neck is prefered. Locating the adjustment at the headstock removes a great deal of mass from the neck and can affect the structural quality of the neck. Most luthiers that located the truss access at the headstock/peghead add what is called a Volute. It serves to strengthen the neck where the peghead begins by adding a bit of mass at that point.

    At the body is fine, just cut the last 1/2 inch or so off the short end of the allen wrench and itll fit.
