Spring reverb is something we’re used to hearing about when it comes to guitar amplifiers. It’s a coil spring stretched the length of the amp’s housing. One end is fed the guitar signal, with a pickup at the other to capture the output. But this spring reverb is on a much grander scale. [Jochem van Grieken] strung up 100 meters of coiled steel wire in a long hallway and the results sound a little bit evil.
A simple piezo element is used as a pickup to amplify the sound coming off of the spring. Above [Jochem] is using what looks like a jeweler’s saw to make some sound on the 3.5mm wire. It’s this portion of the video that sounds demonic to us. In the second half of the demonstration he strikes the wire with a ruler to produce the pew-pew effect from many a sci-fi movie.
This isn’t his first experiment with the concept, it’s just his largest. Also found after the break are a pair of links to his other installations.

If you’re running your own recording studio, you’re going to need a lot of gear that seems excessively esoteric to the non-musically inclined. A rack full of synth gear looks just like any other cabinet of technology you would find in a server room. Electronic music is, for the most part, very utilitarian looking, but there are a few pieces that add a very nice aesthetic touch to any studio. [Peter] made two great looking pieces of hardware – both reverbs – that significantly add to the decor of his studio. As a bonus, they also sound really good.
[Peter]’s spring reverb (Dutch, Google translate) works just the same as any other spring reverb; a speaker puts some music into a slightly stretched spring, and this sound is picked up by another transducer at the opposite end. For this build, [Peter] used a Slinky and a piece of PVC pipe left over from a bathroom remodel. Adding a few jacks, pots, and a preamp, [Peter] had a very nice and extremely large spring reverb.
The plate reverb (translation) is also a staple of pro recording studios around the globe. This reverb is somewhat similar to a spring reverb, except the spring is replaced with a tuned metal plate. [Peter] used a cymbal from a drum set for this piece of kit. Two speakers are attached to the back of the cymbal, one feeds a sound into the cymbal, the other speaker picks up those sounds and sends it to the mixing board.
There’s a lot of really cool musical DIY projects over on [Peter]’s site, along with a few audio demos for each of his DIY projects. We’ve included his reverb demos after the break, feel free to give those a listen.
Thanks go to [geekabit] for sending this one in.
