so i got a gift card to guitar center thats only valid for this weekend....its worth 25 dollars...i wanna get a instructional book or dvd....ive played for a few years but quit for 2 years and then restarted this year...ive always played easy stuff like green day blink 182 and the beatles....so pretty much...ive used power chords and basic chords throughout my entire time of playing....ive just got into a band and we are trying to write music....i have trouble writing anything that doesnt include power chords....and also i'd like to learn soloing/improvising....i dont know very many scales... so what book or dvd that cost 25 or less will help me the most....i need to know very quickly because im gonna go there in a few hours
