Sonik Capsule vs. Expansion Tank?

[princeofroles]

Hi, I own Sonik Capsule Bass (gotta love the group buys!), and am interested in picking up Expansion Tank Bass as well, but can't tell if these are different sound sets... they share some basses, so obviously don't want to bother if they are 90% the same, anyone have any insight? Thanks!

Mostly different material. But some crossover. Enough to warrant buying both however. Especially at the prices they are now.
