LOL!!!!
This post is funny because years back, I wanted to know this very question...
I couldn't figure out if he played a Seagull S6 or a Martin copy Sigma... Well anyway, I bought a Seagull and started to learn to play guitar. I still can't understand why I sound nothing like Mikael.... LOL!!!!
Actually, it's a pretty decent sounding (hand made in Canada) guitar at a very agreeable price.
I read in an interview a few years back that Mikael wanted to get a Martin auditorium guitar eventually when he had enough money (me too). I guess he still is waiting to get the money...
