I'm a beginner looking for a nice acoustic guitar. I am sincerely intent on learning to play and am willing to pay for a quality instrument. My concern is that my fingers are somewhat short, and on some guitars I've tried, getting them fully around the neck (like a G chord) is difficult, if not impossible. Do guitars exist for the digitally challenged, or are the dimensions pretty much standard? Either way, I would like to buy a really nice acoustic and would appreciate any suggestions. Thanks.
