Hi, all. I'm a bass player (40+ years) recently switched to guitar, 4-ish years ago, and new to this group. I am being tempted by the G6120T. However, I am finding that there are about eight squintillion variants of the G6120T. This may be an unanswerable question, but does anyone have any guidance on how one chooses a particular flavor of G6120T? Is there any kind of comparison chart that shows how the different variants differ from one another, or anything like that?
