I’ll try to record something once I have some more tests. Let’s see if I can get it to work!
Very interesting! Is there springs mounted onto the actuator that hit the springs on the reverb tank?
I myself saw one online and thought kind of the same thing. I have to add that something is weird with my build. Maybe it’s just a crappy piezo, but I get a bad low frequency hum. Also one thing I hadn’t properly considered is that I have to create a new exit for air&sound, now that the piezo is covering the original one.
