I have owned this bass since about the late '80s and never have needed to make a neck adjustment (straight as an arrow). I recently switched from tape wounds to TI flats and LOVE the sound! But, I am now noticing small buzz high on the neck. I have read here on TB that TI flats are looser and therefore there is not as much tension on the neck, so the neck may be back bowing (right term?) slightly ( only a couple of notes, e.g. the high A on the E string). This bass has the typical fender truss rod adjustment at the heal. Qs: Sorry if these have been answered before : 1) How much care do I need to take when I first attempt to turn the truss rod given that it hasn't been done in at least 20+ years? Is there any kind of lube ? 2) As long as it doesn't get worse, should I just not bother? and , 3) Which way do I turn it, clockwise or counter-clockwise? I don't want to harm the bass by turning the wrong direction. 4) Or, should I just raise the string at the bridge?
