How often should guitar strings be changed?
Asking when strings should be changed is a loaded question because it can be answered in many ways. However, there are a few things that will make it pretty obvious when you need to change your strings.
Nerdy computer crap time.
If you just bought a Jazzmaster or Jaguar or already own one, unless you have a case with some extra vertical length, you'll notice the one you have will fit a Strat or Tele, but not the offset body guitars.
The Jag/Jazz's extra length means you have to buy a longer bag or case. If you've shopped around, you've probably noticed some fairly high prices.
Fortunately, you have a few cheaper options.
