I totally understand the truss rod concerns (I share them) but life's too short and apparantly there have been no returns in 20 years, my fav guitar(a classical)has no truss rod too :P
It's actually really nice not to have to worry about a truss rod, time will tell if it works out in the long run . The set-up is perfect with 9-46, I ussually use 10-46 but I'm not doing anything to change the setup untill I have to! It actually has a little bit of relief in the neck, it's not dead straight.
It's dead light too, like 6lb light.
Thanks for the comments :)
I wouldn't worry about it anyway :) And I'm not surprised that it has relief, on the contrary.
My strats neck on the other hand requires a little work every now and then. About once every 5-10 years, the neck needs to be pressed back to form (these are the words the luthier used), as the neck can bend on the first few frets. This is also where the normal truss rod takes effect. Well, the guitar was built in 1990 and I'm gonna have the procedure done in the following few months :) I'm the 3rd owner, the procedure has been done once already for this guitar.
The luthier also said that the non-trussrod design was an experiment, and he found out that some of the necks had to treated with the procedure I described above. He quit doing it before there would be too much future work for them. However, outside that procedure the necks work really well, and they don't have any iron colouring the tone. Just pure wood.
