Hello everybody! In the search of the perfect setup to my bass, i came across the fact that i never touched the micro tilt hole in the back of the bass. It is a 78 Jazz. How does it work? what does it do? Is it like there is a subjetive way of doing it? or is it objetive? Also i have the problem that the truss rod doesnt move. Relif is lower than it should, not HORRIBLE, but i wish it was a little higher. But the bullet at the end of the neck (in the head) is completely loosen. Maybe there is something im doing wrong. Or maybe it has to do with the micro tilt. Any advice on either matter is wecoled, thanks!
