Two weeks ago I spent a decent amount of cash and time replacing all the strings on my guitar. They were getting rusty and sounded dull. Since then I've been playing about two hours a day, all going well. But just yesterday the low E string snapped. Of course I could change it but isn't 2 weeks a too short time? Could it be something with my playing, my guitar, or the strings themselves?
FYI I had been playing 'Spit out the bone' by Metallica, which has a LOT of tremolo picking on the low E. This would have led to greater wear, tear and stress on that string, but is it still OK to be getting through a brand new string in 2 weeks? I'm mainly concerned because I'm 15 and there is only so much I can spend on buying strings, so being economical is important for me.
I would be really thankful if someone could tell me if wearing out strings this fast is normal, and how I can possibly increase their longevity.
