我的結他雜記: Guitar strings

How often are we supposed to change strings on guitar? I was told every 30 hours of playing. I seldom change unless it's broken (usually the high E)

I almost stopped playing my Steinberger Spirit after I've bought that Ibanez Acoustic. Maybe I should change the string on my Spirit then I have motivation to play it again. It's common for jazz guitarist to play 013 strings! The heaviest double-ball strings I could find is 011. However, I might stick with the same gauge. Lots of people says that if you switch gauge, the neck will get different string tension and will change the intonation and need to adjust trust rod or the bridge. Sounds too troublesome for me.
