using piezo saddles for synth pickups

[Seanfir]

I've been thinking hard on this for a while. I have my strat successfully equipped with a mike christian piezo system and a bartolini line buffer/preamp to even the eq and Impedance of the pickups... however the system groups all of the pickups in a harness together... so my though is to disassemble a non-working GK-2 or GK-3 pickup and run the piezo's through a simple small low pass filter individually... then send the wires through a small network of coupling caps to allow them to be harnessed directly and not cancel in to mono if gathered before the coupling caps... this should allow both systems to exist independently, allowing the synth to use the piezo's and also the acoustic sound of the saddles through the Bartolini, essentially untouched... Anyone see a problem with this? I was thinking a very small, low voltage coupling cap would work... but i'm not sure about this... since the audio signals are AC... would they cancel or become mono behind the coupling caps as well? Not sure about this... or if some kind of discreet system, matching transformers.... etc... would be necessary... I have a ton of little parts like this here... and just trying to figure it out before I use my tele as a guinea pig!

The pickups in a GK2/3 are not piezo's, so the preamps in those pickups will not be suitable.
You'll need individual piezo preamps for those saddles, and then individual outputs on the 13pin din, and a mixer combining them for an additional audio output

What you want is like a Godin multi... RMC...Richard McClish
