Disclaimer. I am a total guitar beginner; I have no intention of messing with the truss rod if there is no need to, but after I bought my strat-type, I started noticing what I think are intonation problems and decided to spend some time studying the anatomy of the instrument to see where the problem may be. I don't think that the real problem is the neck relief here, but what I noticed on the neck seems weird to me and opinions are appreciated.
This is a picture of my strat-type guitar with an Allen Key fully insterted into the truss rod nut. This is not any key; it is actually the one that came with the instrument.
I am perplexed because the wrench is very close to the wood. Even if the strings were not there, I would not be able to turn the key without damaging the sides of the truss rod hole.
Actually, I tried loosening the strings, removing the string trees, and tried to use the long leg of the Allen key (like this guy here, see the 7th picture). Well, if I do this, I am not even able to reach the nut. I believe the problem in this case is the lower side of the truss rod hole, that is preventing me from aligning the key to the nut.
In short, it seems that the geometry of that thing is a little messed up. As I said before, that key came with the instrument, and its short leg is actually longer than other Allen keys that I have in my house; this means that with those other Allen keys I would not even reach the nut.
- Is there something wrong with the neck?
- Is the truss rod broken or went out of place?
- What does the truss rod nut look like on real Strats?
- Would I need something like this if I were do adjust relief?
The guitar is a Glarry GST.
@Tetsujin is right about sizes. In the end I got a 4 mm Allen T-key with ball end from the same manufacturer, which is the metric version (i.e. it's basically a little thinner) of the imperial one that I posted before. I can confirm that the imperial one will not fit the nut on my Glarry. If you have a Fender or Squier I presume you should be fine with the imperial one, but I can't say for sure.
