As I've come across some of these tabs on the net, one thing I have noticed a lot is that a lot of these people tend to transcribe things closer to the middle of the fretboard instead of all the way down. You know, there are many 5s, 6s, and 7s instead of 0s, 1s, and 2s. I personally prefer the latter. But is there any reason for this? Is there something I'm not seeing?
