Hahaha, I tried this afternoon, Im not that good with my ears, but still and just find out the begginning Which is pretty obvious, but still... D: I was trying too Koshi Tantan D: and just the beggining >.< I will keep trying, Switch is a cool song!
I've been using ren-00's guitar chords for Switch and going through the song listening for the bass notes. I think I have most of it, except for a few of the riffs. I can write it up in tab notation in the next few days, and maybe we can compare what we have. I've never fully tabbed a song before, so hopefully I'm not too far off.
I also did the same thing for Anata ga Mawaru, so I may post that too once I finish it up.
I also figured out the most parts of it just have some problems with the pre-chorus and the chorus riff I watched the live version many times, but I just don't get it right.
