All the talk about flexing wood and necks? Nope, I think all that talk passed me by!
A couple of carbon steel rods in the neck, a 5-piece laminate of some really good tone wood, and I think any 'neck flexing' problems are well and truly behind you ;)
Please don't start playing, that guitar sounds truly, brutally horrible ;)

edit; wez beat me to it, and yes, that is truly, brutally ugly!
