Reverb Springs

[Jules Ryckebusch]

I made a spring reverb  in high school for a science project. I took 
a really loose spring, almost a "slinky" and glued it to two small 
speakers. I drove one with a small amp and used the other one as a 
pick-up with a 8-2000 ohm coupling transformer (real common from AM 
radios and Radio Shack in late 70's). It worked real well, AND if you 
plucked the spring, it made that Star Trek photon torpedo launch 
sound. I have been wanting to build a usable unit using spring 
assemblies from Parts Express.
