If you´re a seasoned guitarrist, you´ll learn nothing new here. If you´re an intermediate guitarrist just looking for tips, you´ll find none here. If you´re a beginer, you´ll learn what the techs do when you visit them to have some maintanance done on your guitar, but it doesn´t really explain in full detail how to DO IT YOURSELF.
Perhaps if you read the book that accompanies the dvd you may find more info, but just the dvd is really kinda pointless.
The DVD cover says that there´s a member´s code included which is required to enter their website and check stuff there, however, my dvd was new and factory-sealed and it had nothing inside but the disc.
In plain words. There´s nothing on this dvd that uou can´t download from the internet or ask around, saving the money you pay for it.
