trussrod adjustment

Recommended Posts

There was very little neck relief on my Casino Coupe. So I decided to do something about it.

 

The truss rod felt very loose to me, as if there was no engagement there. I only ventured a 1/4 turn and could see no change afterwards. I gave it a half hour; still no change. After another half hour there was still no change.

 

Now on some guitars you can see a change immediately. I did a similar adjustment on my PRS a short while ago, and the neck profile changed instantly.

 

Back to the C-Coupe: The following day there was still no visible change, so once again I slackened the strings and gave another 1/4 turn. Again it felt too loose. I then ventured further 1/4 turn and this time I felt some resistance; but not much!

 

After re-tensioning the strings though, there was still no change in the neck. I left it another day and then bingo! I now actually had some relief, but maybe a little too much this time. I made no further adjustment except to lower the action and retune. It felt different of course, and maybe felt slightly better than before.

 

I will leave it another day and then see about having another try. I've never known a neck to react so slowly before. :huh:

I'm certainly no expert in this area, as many on this forum are, but I'm thinking your truss rod isn't working. From everything I've ever read you should be getting some resistance and a noticeable change with something like a 1/4" turn within a short period of time, (like an hour or so at most). YMMV, and hopefully someone more knowledgeable than me will chime in here.

There are necks which take lots of patience until the adjustment has stabilized. Any material combination of neck and fretboard can be affected. My experiences with brand-new guitars say ten to twenty days. It's always just a guess for the first time if 20% of the adjustment works instantly and 80% within the next two weeks or vice versa.

 

Used guitars may become very rigid at the given setting and thus reluctant to react, or they move significantly delayed. Anyway, as soon as the "new" relief is fine and solid, that's it!

Like I said...

That's one of the reasons I like this place. I never knew this. You can learn something new every day.

I'm with you Dennis & Merciful, love this forum.

 

Just got my Coupe last week, great little guitar, but like M.E. I found the neck needing some relief, was pondering posting on the subject &

VIOLIN . . . I mean VIOLA, just what I was needing.

 

Merciful Evans - only question I have is which way did you turn the rod, don't want to dis-engage it

 

Got mine in the sunburst flavor, light guitar - 5 lb 10 oz, had to remove the pick guard 1st thing before tuning, beeuutafull finish, couldn't

hide it behind a p/g.

[biggrin] That's understood, I also wouldn't want to hide this beauty. [wub] Congrats on your pretty catch! [thumbup]

Truss rod adjustment:

I turned mine clockwise.

 

With the allen key engaged:

 

Clockwise to correct for back bow (higher in the middle of fingerboard)

Anti-clockwise to correct for too much relief (high points at each end & ‘dipped’ in the middle)

 

I still haven't readjusted to more finely correct mine yet. Its actually pretty good as it is anyway.

 

 

Love that sunburst on your CC LongJohn. I never thought about removing the pick guard. I may do the same.
