For anyone curious/about to get their panties in a twist :
Zombass 3 is NOT a 'next gen' Zombass 2. Your Zombass 2 is not going to be replaced here.
Zombass 3 is more of an expansion then anything.
Zombass 3 is a metal-oriented, slimmed-down and simpler version of Zombass 2.
The bass, if not already noticed, is a 6 string, capable of down to E0 for the uber-low tuning shit.
Being a different bass, it has a different tone. The low end is a bit more controlled, and the top end is a little bit more unique.
It's very percussive, but very versatile.
However, Alex isn't making it as complicated and manipulative as Zombass 2. A little less parameters to mess with.
It doesn't cover quite the same range of musical styles that Zombass 2 does, but it does the metal stuff a bit better, at least from my perspective.
