I did a lot of guessing on this one.

It is possible to do it with no guessing but it requires a lot of time trying to figure out if a square possibly can be correct ie, it can't go in this one because that would mean this and this and then that's a contradiction therefore it's a X kinda thing... So this should have a higher difficulty rating I think...

Couldn't figure out how to do it completely by logic, but it was easy to solve using temp. mode.

That was really easy.

It's completely logical except for the last 4 dots. But those are easy enough to figure out.

This guitar has a slightly crooked neck, no tuning pegs.

Thank you.
