its $10. but when I went to the RB3 store it didn't require a code, just my money.
I'm tempted by the squier. Only ever fiddled with a friends guitar while at school, but I can imagine the feel of proper strings over the frets would be quite different from the mustang's buttons. Or does the mustang still feel good?
I'm also thinking it could be good to get my son into playing an instrument. But that might apply to the pro drums too - he likes the drums as much as guitar at the moment. He's 9, so would there be any advantage to the mustang in terms of less pressure required on the frets and therefore a little easier to practice with?
