is this possible?

ok, so there a way to replace the pitch antenna with a long metal plate to have a slide control pitch?

kinda like a cross between a theremin and a tannerin

No. It isn't.

oh well, i guess its on to plan B. trying to track down a fingerboard theremin schematic

This (http://www.paia.com/LabNotes/) may help.

awesome, thanks. the theretar may now exist soon... well eventually

Post a pic when it is done....
