I recently learned about a really fun blog called Retro Synth Ads. If you're like me and spent your youth pouring through issues of magazines like Keyboard, Electronic Musician, and others looking at gear, this blog will bring back some great memories.
In January, they featured a theremin that I'll admit I was not very familiar with: the Big Briar Model 500 Theremin Controller (circa 1984). Check out the post for more information on it and another related Big Briar product, the model 331 Touch Plate.
