The natural frequency of the super hard/stiff woods contributes to something special, I have found. My Bubinga Corvette STD 5 is over 12 pounds, and it feels like I am playing concrete. There is a higher frequency ring to it. Not for everyone, but definitely aggressive.
I am a fan of Ryan Martinie's sound as well as the guy from Incubus. I think Korn's bassist also uses Warwick
Korn's bassist uses an Ibanez.
Not that I know anything about Fieldy or anything though.
