Question about multinecked guitars...?

Question

how come the neck closest to the player has 12 tuning pegs instead of 6 on a multinecked guitar?

Answer 1

12 string guitars are a little harder to tune than a six string - I can tune a six string with my eyes closed, but with the 12 string you need to see the tuning keys, so that's probably why the 12 string's on top.

Answer 2

It's the 12 string half. These guitars have the strings in 6 pairs and gives them a fuller, richer sound.

Answer 3

This is just a guess, but it's a bit more comfortable to play the bottom neck. Since six-string guitars are more commonly played than twelve-string guitars, it makes sense to put it in the more comfortable position.
