I happened to stumble upon a used VFE Mini Mu the other day at my local Mom & Pop for $100. I’ve always been curious about these but there isn’t a whole lot about them online. Anyway, I picked it up and I’m very impressed. It really nails that Mu-Tron/Qtron vibe and feel while being small, having normal power requirements and most importantly a master volume control! I think this may be my new favorite non-huge envelope filter! Anybody else out there ever try one?
