Whatever it's called it's a GuitarPCB Paramix in a little box.
I've had this board for a couple of years, built, it came as a freebie, and never got round to sticking it in an enclosure until now.
A friend gave me an old 1980s Rotel hifi to strip down for parts, and out came a 50K dual concentric pot, which is perfect for the dry/wet mix pots. The other pot is a dual gang with an extra pin and track which goes to the centre of the main track. Only using one gang, but the shaft length matches the dual concentric. Any ideas what the other pin is for?
Not as tidy as I'd like, not easy to get it all in there.
This thing is amazing, the options are limitless.
