If I remember correctly from the behind the music 15+ years ago, Nikki stole a guitar from a shop only to realize later it was a bass. So he said "whelp, I guess I'll learn to play bass".

I can't help but think he does that so he can have a chuckle about it:) He's one hell of a player and sounds great.

I thought Mick Mars wrote all their riffs and he's an absolute fucking beast, I thought Nikki could never really play in the first place

I might be confusing him for sid vicious though

Nikki Sixx recently started taking guitar and bass lessons.
