Give Grattler a beefier sound

[Aikii]

I absolutely love the look & concept of the Grattler, being a huge handheld flak cannon that blasts through everything and explodes...... but the sound, is so silly. 

 

It sounds like some kind of pew-pew Corpus weapon almost, it's not big and heavy at all.  I really imagined it would have more of a powerful, bassy drumming sound, but it feels more like shooting paper balls at the enemies.
