Big Briar Inc. Model 500 Theremin Controller "Space-Controlled Music" ad, Keyboard 1984

Big Briar Inc.'s Model 500 Theremin Controller "Space-Controlled Music" black and white 1/4-page advertisement from the bottom-left corner of page 60 in the May 1984 issue of Keyboard Magazine.

"Space-controlled music"! Why does the Theremin always get thrown in to the "space" bucket?!?!

Scratch that. I know exactly why... hee hee  :)

If you recall from my last blog post, I touched upon (pun intended) Big Briar's Model 331 Touch Plate. A great alternative controller, especially for live performances. I'm trying desperately to hunt one down as we speak.

But another even more nifty alternative controller from Bob Moog's Big Briar Inc. around the same time period (and one that I would also love to get my greedy, dirty little paws on) is the Model 500 Theremin Controller.

Take the coolness and interactivity of the original Theremin, strip out the audio circuitry, and replace with two control voltage outputs for pitch and volume. Actually... not just for pitch and volume. More on that later.

A quick search of the Web found one of the earlier spec sheets for the Model 500 on's Web site for one of its auctions for Big Briar's 1982 controller pamphlet and blueprints. Click on that first big image and it will allow you to scroll through the other pages, including an image of the Model 500 page. This page has some great reference info on the 500, including the fact that it came with options for digital outputs and a line-operated power supply.

The actual design of the Model 500 Theremin Controller looks to have changed quite a bit between that 1982 pamphlet and the 1984 ad. From what basically looked like a block of wood to something that more closely resembled the sleekness of the Model 331 touch plate. Although I couldn't find any good quality colour photos of Model 500 during my quick Google search, I imagine it looks much like that gorgeous photo of the Model 331 found on that Buxton Collection Web site I linked to last week (see image at right).

Design aside, its those control voltage outputs I love most. Let me repeat that, and maybe yell it - CONTROL VOLTAGES!!!

So, as the ad states, you can connect this baby to your favorite synth (such as a lovely Moog Modular synth) and start controlling "pitch, volume, brightness - any parameter that can be voltage controlled".   According to the pamphlet, there was also the addition of a gate signal "that goes on as the right hand begins to approach the pitch antenna, thus making it convenient to squelch the tone when no musician is near the controller."

Squelch! Excellent!

What this all does is open up Theremin-like control to a much wider range of sound. Any waveform you can create with your synth can be theremized (so too is a word! And if it's not, that shizzle needs to be trademarked pronto). this brings me to another reason I'm stoked about this ad.  NAMM has just concluded, and one of the products that stood out for me and my close circle of online synth-nuts was Moog's new Theremini.

Damn! That's the spaciest-lookin' Theremin yet! That thing would look as good in my studio as it would on the set of Star Trek's control room.

And the best news is that, like the Model 500 Theremin Controller, the Theremini opens up a whole new range of sounds to the user by including "a powerful sound engine derived from Moog's award winning synthesizer, Animoog"! PLUS you get pitch-correction for us beginners, pitch CV out, and a mini-USB jack for MIDI.

MoFo! Are you kidding me? Do I have to punch you all in the neck to show you how excited I am.

*This* has just taken #1 spot on my "next piece of kit" list.
