NOTE: When you go to a music instrument shop and start asking questions, if the person to whom you are talking is knowledgeable and helpful, then you’re in the right place. If they don’t seem to know the answers or talk too much without really listening to you, chances are you’re in the wrong place!
Some people have very high acid (ph) levels in their perspiration. This is probably the number one cause of strings wearing out quickly. If this is you, the best thing is to keep a couple of dry towels handy to wipe down the strings each time you put the instrument on a stand or in a case.
Any guitar in decent working condition will suffice for lessons and practice since the tuning and fingering positions are the same regardless of the type of guitar.
