I have a JP FBR with the piezo and currently use two different cables to send the electric signal direct to my amp, and the piezo signal right to the PA. I've been looking at videos of JP's live rig and his tech Matt explained it, and as I understand it, is that JP runs one stereo cable from the guitar electric output to the Framptone amp switcher pedal, then it splits the signals, one to his electric rig and one right to the PA for the piezo. So if I understand correctly, instead of using the position switch on the guitar to change from the electric pickups to the piezo pickups - he can switch the signal via the Framptone pedal.
I would like to split the signal the same way - the only part I don't understand is how you can do this only using one cable coming out of the guitar - unless I am missing something.
Thanks any input would be appreciated.
