That’s a close-up of one end of the spring tank in my TASCAM RS-20 Spring Reverb. One detail that surprised me a little when I opened it up is that the transducers appear to be symmetric, i.e. the part that feeds audio into the springs appears to be the same as the part that picks up the resulting signal. I’ve never opened up a spring reverb before but somehow I expected the drivers to be different than the receivers.
