I don't want to do string changes to play different songs that interest me. My profile is I want to practice for a little while, then play something that I've heard while working that I want to try, for instance I wanted to play animals by Architects in C#, tomorrow I might want to try the beginning notes of an A7X song, etc. It keeps me focused and motivated. I can't sit and do strum and chords for more than an hour, my mind loses focus. So I'll probably pay a little extra to get a few guitars set in place.
