How to make your Axe-Bass

I'm really sorry, I'm very very late (one month... Very late)
But, if it don't took me so much time do to it, I put a little more time to translate it.
And I had to re-motivate myself because it was a little harder than expected.
Indeed, I understand English so much better than I speak it -_-'

So, I hope I'm not to late and it will help you to do your own axe-bass
Enjoy !
