But I would prefer a method where I could feed the 13 pin gear along with the wireless MIDI from FTP.
|---->GK-3 -> 13pin
One hex PU 8 pin---|
|---->FTP controller > wireless MIDI
and the "Y" Adapter could be very straight forward.
Mount one hex PU of choice( FTP, GK-3, GK-2A, G1D, PU100, AIX-101) Let the stock Hex PU Cable be the input to the Custom Mag Hex PU "Y-Splitter" to feed two targets.
On this Custom Mag Hex PU "Y-Splitter" there MUST be 12 "coupling capacitors":
* Six Caps to feed the Hex PU String Inputs on FTP Controller.
* Six Caps to feed the Hex PU String Inputs on the GK3 preamp target.
The 12 Capacitors are required to prevent DC voltage interference and offsets between the two different systems.
Small Surface Mount caps are available, but must be of adequate capacity to pass the low fundamental frequencies of the Guitar. http://en.wikipedia.org/wiki/Capacitive_coupling
