Quick question re truss rod

[Deaky]

Hi guys

I put a set of Labella flats 45-105 on my ASAT the other day after having Thomastik flats on.

In trying to adjust the truss rod I put the longer end of the allen wrench into the neck but it would not budge. I then put the shorter end in which fitted perfectly which when I turned the rod it turned very smoothly.

I am just looking for some reassurance that I havent damaged either the rod or the neck by doing this. The neck has slight relief which is perfect for me and it certainly plays perfect as my ASAT has always done.

Any help would be greatly appreciated.

Oh and the ASAT loves LaBella flats


Cheers

Short answer, no damage.

By using the longer arm of the wrench to engage the nut, you greatly decreased the amount of leverage available with the shorter arm.
When using the short arm to engage the nut, the available leverage was multiplied, allowing the nut to turn smoothly with little effort.

It's almost impossible (for me) to get the truss rod to move with the long end. Your bass should be fine!

Thanks guys I really appreciate the quick replys. Admittedly when I was trying to turn it it was going nowhere until I put the shorter end in and it went very smoothly.

Phew...

Thanks guys :-)

Plus i did give it quite a firm pull and it didnt seem to move any!!!

Do you need to loosen the strings when making truss rod adjustments? Mine seem to turn easier when the strings are loosened up some.

if the rod is hard to tighten, that can be a good idea, along with just pushing the neck into backbow while you tighten.
