I think the version currently for sale might had the 12AX7 as opposed to the WBIM AU.The Finally now for sale is the same as the WBIM pedal, supplier sent the wrong print on the last batch of boxes so they are being used.
I think that is right.
See post 21,794 - 21,796 on page 1090, I asked the same question back then.
I don't know about any earlier pedals if you are talking about second hand pedals on the market.

I have a Space Heater which is a Finally with out all the DI stuff' just Vol and gain. It's frickin amazing on bass.
Warning cranking both the gain and volume will kill small furry animals at 20 paces!
