Rocksmith 2014 Edition

This cheevo is awarded for performing a soundcheck.

I got this cheevo the 1st time I loaded the game up, when the game ran through the initial start up selecting head stock, lefty or right handed and then performed the calibration and tuning of my guitar.
Once all that finished the cheevo popped.

If you forced the skipping of this process then I am assuming you can go into the options menu, tuning and then perform a calibration by pressing and after the cheevo should pop but I would need some1 to confirm this.
