hi, Its been about 2 months that i started playin a guitar.... I have a gbna jazz guitar... Now, today at a shop that I went to put a pick up, the person there says the guitars neck has bent..... I couldnt observe it, but that bothers me.... Anyway, if it is so that a neck would bend, what should I do to avoid it? I also hear a few saying I shouldnt use different strings of different brands.... Does that also make a difference?
