Oh yeah, now that I see your thread thats definitely a first. When you said it was a "middle" version I thought that maybe there was a time where they had the white pedal and graphics on the exterior, and new updated electronics on the interior and that the version before was white graphics and older electronics. I had never seen the truly first model with the all blue box. I didnt know that existed. So yeah, second gen is the new ampeg like logo on the dark box.Eyeballkid, FYI I started a post in the effects forum about the generation of my SFT.
