    Bongo trussrod

    Hi

    I just wanted to know which way my Bongo neck should bend if I tighten the trussrod
    Should I get more arc or bow?
    Bow = convex
    Arc = concave
    for me

    If you have it on a strap and standing like me...

    Lefty = loose or lower. Pull up towards you.

    righty = tighty or raises. Push down.

    Best way I can describe it.

    If you tighten the trussrod you´ll get a more straight neck with less bow. The trussrod will push the neck backwards.

    With the bass in your lap in playing position, turning the wheel towards the ground (clockwise) will tighten the truss rod, straightening the neck.

    If you turn it towards you (counterclockwise), it will loosen the truss, adding more relief.

    less relief / flatter = lower action
    more relief / bow = higher action
    do NOT use cheap tools to adjust with. they might break and scrape up your pressious!
    also, if you are lucky enough to have a 100th namm sr4: the truss works the other way around on that one!

    Since noone really answered the original question (does anybody actually read these days.... ?!) I'll have a try...

    Tightening the truss rod straightens the neck, making it less concave. With low or no string tension you can even get to the point where tightening the truss rod bends the neck to a convex shape. But you should never have a convex neck! Always have a little concave curve to it. It's called "relief" and allows the string to vibrate more freely.
    Have bass. Will play.

    Wow - 6 replies already
    I loosened the trussrod completely and the neck seems pretty straight.
    I want a bit more relief - hence my question
    Looks like I'm already maxed out (max space between neck and strings in the middle of the neck with trussrod completely loosened)
    I have set it at about 1/4 turn tightened from completely released
    I have also added a small shim under the neck mount(closest to headstock) to tilt the neck up slightly
    Still get a tiny bit of buzz as I release the strings - may just be me.
    Any other suggestions?

    Tanx

    yes. i presume your location is correct (france). in that case you should use this "chain of command"

    1. contact your dealer. they should be able to help you with this problem. in conjunction with the distributor they will do their best to keep ernie balls customer service on the excellent level it is!

    2. if that fails try talking to the distributor directly. they can be found on the music-man.com homepage.

    hth!

    Be patient.

    I rarely adjust more than 1/4 turn of the truss rod at a time. Let it sit a few days and you may be in for a surprise.

    Looks like a Trans White, so I would guess it was our very own Gav.
