I know that it isn't exactly a pedal, nor is it guitar-related, but, it is a musical instrument and is still true to the whole idea of DIY, anyway, I thought that I would start a thread about it since I'm going to be dragging it out of retirement so that I can play it at an up and coming gig, and I'm going to be doing a bit of servicing work on it to get it working at it's best, it needs some adjustments done to it, and thought you guys would be interested in reading about it.
Now in order to do the adjustments, I need to buy a set of plastic Radio alignment tools from Jaycar Electronics, which I'll do tomorrow, I'll also post some pics of it and maybe an audio demo.....stay tuned (pun not necessarily intended).
Here's some pics of my Deluxe Theremin:
Okay, so what is it anyway?, it's an electronic musical instrument that you play without even touching it, it has two antennae attached to it, one antenna is positioned vertically and is called the "Pitch Antenna", the other antenna is positioned horizontally and is called the "Volume Antenna", you can control the pitch of the sound that the Theremin makes by positioning your right-hand closer to, or further away from the Pitch Antenna, the closer you position your hand to the pitch antenna, the higher the pitch of the sound that the Theremin makes, and vice versa, you can also control the loudness of the sound that the Theremin makes by positioning your left-hand closer to or further away from the Volume antenna, the closer your hand is, the softer the sound produced by the Theremin is, and vice versa, so, even though the Theremin is not even touched by the person playing it, the person still has full control over both the pitch and loudness of the sound produced by the Theremin, have a listen to the song "Good Vibrations" by the Beach boys to get an idea of what the Theremin actually sounds like, pay particular attention to the pure wailing sound in the choruses, that's what a Theremin sounds like.
Here's another example, this time it is an old 1929 RCA Theremin that uses Valves instead of Transistors to produce musical sounds, notice how the guy playing it is controlling both the pitch, and the volume of the musical notes by positioning his hands relative to the two antennae, he doesn't even touch the instrument while playing it:
