What kind of instrument is this?

A hella badass one.
No more making fun of the band kids

A fancy ass violin or viola

It's not an instrument, it's a dual disk

Looks like some kind of bat'leth!

It looks like a Klingon violin

Does it play heavy metal?

Only level 90 Bard Masters can equip this.
KASS GET IN HERE I FOUND A NEW VIOLIN

An instrument of death

I hope that plays some heavy metal

for when you want to play during the zombie apocalypse...or mad max uni

I play the violin and i'll just mention that that would be hella uncomfterable to play on

The strings of the God-Empress.
