It may not matter in your case to have the muIII in the middle of the chain if your other effects play well with it. I have always had to place mine first. Also, if you plan on using other effects with the Qtron+ like OD or octave pedals, I have found having the octave and one of my many OD pedals placed in the effects loop of the Qtron, it plays nicely with others that way if all else fails. With my effects switcher, I haven't had issues with my pedals anymore, but still I have the signal hit the Qtron first.
I think it interesting to boost before the envelope filter, I would have to readjust the pedal to get the sound I like. Unless it is left on constantly for driving the amp. There are many guitarists that follow their own ways with pedals and get some cool sounds. Carry on my wayward son.
