That neck is insane! This guy makes some great quality content!

Just noticed you're from Darwin, I've just moved from there at the end of last year! Great place!

Aluminium necks have been done before, certainly back in the '70s by Travis Bean and Kramer. My friend Ivan had a Travis Bean bass back then, which sounded lovely, but did have a tendency to go very out of tune when the temperature changed.
