I have been interested in one of these but I promised myself that no new pedals until I unload one or two. Just need to find buyers for a 5150 OD and Koko Reloaded! Could hit you up if I can make that happen.
Appears to be V1. But the ones I've seen had the knob functions reversed, and the switch on the other side.
V2 definitely have no switch, and an added bite and tight knob. I've had 2 of those, and now a V3, which has the jacks on the top, and is much quieter, (although they're already super quiet to begin with).
I'm pretty sure V1 has clipping diodes, whereas V2 and up do not. The clarity on these is ridiculous. I went back and forth with these and a Buxom Boost, and just love the Savage Drive. Aggressive, yet little tone coloration, since you really only need to use the controls sparingly.
