The logical thing to do is use a standard ganged pot and lose the
ability to adjust them separately.

Yes, I thought that....

Re the pinout, again the logical thing is to connect all wires together
each via a say 1k resistor, switch on and use a sig gen or finger to
find out which has no sensitivity (common ground), which has max
senitivity (to wipers of pot tracks) and the other 2 will be the high
ends of the pot tracks.

Thanks, a great idea. But actually, I recently figured out myself a
different kind of idea, would that work? The thought:
-(I actually have already known the gnd, since it's easy to measure
ohmically to some known gnd point), then:
-To feed a signal to the input of the amp
-To find by a scope, which two wires have that signal -- the high ends
-The rest two ones -- the wipers

Would this be a reliable way?

Thanks in advance.
