Hi mysterio123,
I'm John and am very new to this forum, but let me share with you 2 more useful tips for buying an acoustic guitar, to add on to theunknown's points
1.Action-
Refers to the distance of the strings from the fretboard. If it's too low, your strings will keep buzzing. On the other hand, if its too high you will have difficulty pressing the strings. For beginners, I always recommend getting a guitar with low action, so that its easier to press.
2.Quality of the guitar
Quite self explanatory, but don't get any guitar that has scratches, dents or cracks in the body.
On a last note, not that i don't support Maestro, but I am reluctant to buy their guitars as a friend of mine had her Maestro neck warped in just two weeks after buying it for no apparent reason a few years back. Maybe they have improved, but I still think lots more needs to be done for their QC.
Hope this helps!
