Springatron 3000: Reverb Made From Slinkys and Cucumbers

By Alex in Gadgets, Hacks & Mods, Music on Nov 29, 2008 at 1:22 pm

Nick of Nick’s World of Synthesizers decided to build a spring reverberator … out of Slinky and cucumber! Here’s the Springatron 3000:

This is basically a giant spring reverb made from 10 slinkys. I was trying to make the best sounding spring reverb possible, I think I achieved this but it is probably the most inconvenient spring reverb ever made. The reverb time (sustain) is so long that the springs need damping and I found that the best material for doing this is a slice of cucumber wedged under the end of each spring, other materials like foam or rubber tend to kill all the treble.

    Awesome! Sounds like a horror movie sound track. It actually creeped me out.

    Many years ago I made a reverb out of a spring from a roller blind, a speaker to drive the spring, and a WWII earphone as a microphone. Powered from a couple of home-brew tube amps. Sounded pretty good, even if it wasn’t very portable!
