its the original version with the mid-switch. sounds amazing! I can see how the mid switch would help you cut through in a mix, but truth be told it sounds a lot better when off. completely different animal from the mammoth... this one is warm and full where the mammoth is synthy and cutting. can probably use both for different things 8)
haha communist pig! the bad thing about it is that it's hard to find the perfect volume to match your original bass volume. the volume knob won't really be your friend. Especially when I started using it, it could have been set too soft or really just too loud that the people on the table beside you just start closing their ears until you kneel to adjust. Sounds good in a recording session though.
