PCB comparable as EHX Nano Q-Tron

[harmaes]

Are the envelope filters by PPCB or others comparable to the EHX Nano Q-Tron pedal?
Looking to build something comparable with a volume control as well.

Since the q-Tron is essentially a Mu Tron 3, if Madbean starts selling the VFE projects again, the MiniMu is fantastic. You can always inquire on the madbean forums if anyone has a spare board.

I think the FuzzDog Mootron is the closest I've seen.
PPCB doesn't currently have a Mu-Tron derived circuit (that I've seen- I'd love to be wrong). There is the Pro-Filter, but you'd have to hack in your own peak detector
