The wulitzer reed organ my parents had used capacitive pickups. This was 
back in tube days and the back plate was elevated to 400v... maybe not 
something to use in a handheld reed machine. The speakers used a field 
coil instead of permanent magnets which also acted as power supply chokes.

(yes I got stung by the pick power at least once)
