How about this - 8 pots, 8 jacks, no switch. Configured as 2 3x1 mixers,
each with 3 input and 1 output level controls. Output of mixer 1 is
normalled to a hidden 4th summing node input on mixer 2 (no input jack or
pot). Plugging a jack into output 1 disconnects the normalling and you have
2 3x1 mixers. Use only output 2, and you have 1 6x1 mixer. You might need a
pulldown resistor on the hidden input so that it doesn't flop around when it
is disconnected. Does this sound feasible?
