Hello. I just wanted to know how importat is in this course (and for learning guitar in general) the whammy bar. I can´t install this thing, I don´t know if it is a problem with the guitar or the bar, but I haven´t been able to put the bar on its place.

I´m just a beguinner (I´m learning how to play Hickory Ridge) but I was wondering if it is a good idea to learn more difficult songs (I have in mind one of T Rex) for someone that is just starting. What easy rock songs would you recomend me?

Muchas gracias :)
