hi, i have a homemade plate i inherited that was in disarray. after a complete deconstruction, i was able to rebuild the driver, and got the plate working. however, i have only been able to make a successful return out of a pzm mic pointed at the plate(i know this is caveman as hell, but what are you gonna do?) here's my question:
there is a pickup installed in the plate, but i when i have tried to wire it as a return, i can only get it to come back dry. it appears the pickup has one wire(signal, right?) coming from the part that is NOT physically connected to the actual plate(looks like a very tiny driver cone, but not wound or anything), and the other wire(ground, right?) is soldered to a sheathing piece that IS physically connected to the plate via screw. i have ran this back as a return on a normal signal/ground cable to a mic pre, or even direct into a channel, but it only seems to come back basically dry. tried switching polarity, same thing.
how do i fix this to actually work as a pickup? thanks for the help.
