A so called Multi-Plexer is currently
up for grabs on eBay. Apparently the circuit was designed in the 70s and only a few units were sold recently. This
sound sample is very Sci-Fi almost like a very deep tremolo effect with some slap back reverb. Apparently any sound source can be processed with this box. The auction description mentions an analog signal sent around in a circle and the result being a product of heavy manipulations. It seems like this can almost be a ring modulator with an LFO, but if anyone has info please do comment.

I like the look of the Terrapin - those are some really big LDRs! The back of the board pic is interesting too. Looks like the builder used the toner transfer technique to etch the PCB, but chose not to remove the toner. Would do a reasonable job at preventing corrosion I suppose.

Hello, I just ran across this web site. Thanks for the ad plug! I am the creator of the Multi-Plexer. The circuit boards are developed with a posi-photo-etch system. I have sold about 15 units and everyone seems to enjoy the unit. I am in process of making the version 2. The new Multi-Plexer will have a updated function to allow frequency modulation of the input signal, rather than just acting as a mixer. The unit on the ebay now is the last of V-1. Feel free to contact me. My home e-mail is d-lab500@comcast.net.
