[sdiy] Spring Reverb silliness

[Tim Parkhurst]

The thread about the spring reverb drive circuit got me thinking. How about
putting a small speaker and microphone in the reverb tank and feeding the
signal back to the reverb input (perhaps with a slight delay) to get
feedback and/or sustain? Maybe you don't even need the microphone for
feedback, since the signal from the speaker will influence the springs. I'm
sure I've heard of doing this before, but I've never seen an actual
application. Perhaps the feedback signal could be filtered and converted to
a DC control voltage that would keep the VCF and VCA open (or control some
other tone quality or a wave folder/mangler). A non acoustic feedback
circuit could easily be set up from the reverb output back to the input, but
I can help thinking that the qualities imparted by a speaker in the tank
would be more interesting. Whaddaya think? Any Van Halen wannabees out
there?
