Great idea!
It looks like easily to rebuild - what kind (lin / log - ??? kOhm) of pots do you use?
3 way mixer or passive attenuator

Yes, it is quite a straightforward build, this one uses 50KOhm log pots, though I believe it could work well too with different values.
did you use an existing pcb for this build or is it something you designed yourself on a breadboard?
I designed my own PCB, the PCB is parallel to the front panel, and all pots and jacks are PCB-mounted, no wiring :-)
