Thanks for the comparison, Matt. I got the Micro-tron a couple days ago. I love it -- but don't have a Mu (or Tru-tron) to compare it to -- so this demo helps. Super close. I will say that the Micro-tron is a big step up from the Q. I did the Waldo mod on the Q, which definitely helped open it up (and was well-worth doing), but with the Mu, for the first time, I feel like I have a pedal that really quacks the way I want it to.
