I just got mine today, number 12. My first impressions are: it is heavy for small size, looks hand made but by a quality craftsman(or woman), everything screams quality from pot resistance to finish to knobs to wood, sonics and response are beuitiful and dynamic respectfully. While it beats my other favorites in looks and touch I must give it some time before I can give an honest opinion on tone. For reference, my favs are Octavius Squeezer, Mutron and any of the Source Audio BEFs. For now I think the envelope is close to as versatile as the Octavius, which is the most versatile on the market in my opinion. I'm talking envelope, filter type obviously is owned by Source Audio, no debate there. I will post more thoughts and hopefully a demo soon. But with confidence, this pedal is the best original analog filter to come out in a long while!
