A while back Trevor, before moving back to the East Coast, got a request to see what would happen if a piezo pickup was put under the nut. We read up on Frank Zappa putting something like a Barcus Berry on the peghead of his guitar. Fred Frith (cool article here) has a magnetic pickup over the strings in front of the nut. We asked Pick Up The World to make a piezo to fit. The sound was amazingly responsive and picked up the string mainly behind the fretting hand and acoustics off the neck. Trev ran a channel down the neck just under the fingerboard to run the cable down to the control cavity.
