I did try to play with truss rod and action, but recently checked the frets again and I did a lousy job crowning them. I started the fret work on the 24th fret and went backwards, so I started very badly and got better as I progressed. I don't know why I didn't check them before assembling the whole thing, but I'm quite happy with this being my first built. I made other errors along the way, but I'm not going to share them here heheje
