I've been playing guitar for almost a year. I've been playing electric guitar for almost five months. I have an American Standard that got set up 2 months ago. I am breaking my high e when I do a 1 1/2 bend. I had a d'adarrio 9, a slinky 10, a gilmour 10 and they last a week. I know it's probably my technique. I'm just going to keep the backing plate off so I don't strip the screws. I have a lesson tonight so I'll ask my professor. Any suggestions?
