Maybe I can't fix it, but I can fix it so no one can fix it

I could hear no noticeable phase interaction between the piezo and magnetic pickups, so I modified the circuit to sum the piezo phase shift against itself. Now can hear a difference, but it's not striking enough to make it a worthwhile sonic choice. But I learned a lot and enjoyed the journey in building this instrument.
