EMG EXG expander and SPC presence control

[erio fraga]

Maybe this is not an appropriated question to this forum, but does anybody have the schematics of the EMG's EXG expander and SPC presence control ?
I know they are indicated to be used with active pick-up, but do you believe they can be used with the passive ones ?

Thanks

the spc is based around the craiganderton design..
