See the D-Labs label at the bottom of this post for previous posts including audio demos. The following description if from the auction:

"This is the D-Lab Multiplexer (also known as Classic Multi-Plexer).
This is a wavefom synth box that is really cool, and very difficult to find.

Unlike many similar synth boxes, the Multi-Plexer has an input, not just an output, so it can be used with other guitar pedals or other synth modules, or maybe even a microphone!

I used it with guitar signal input, and also used it with other synth modules in front of it (such as the BBS module in my other auction). Fun to experiment with other pedals in the chain, like bitcrushers, octave, fuzz, delay etc. It likes to see a fairly strong guitar signal.

It's pretty difficult to explain what it sounds like, but there is a synth signal with depth and sustain that interacts with the input signal, and there is also a modulation effect with rate and frequency. It's like there's a phaser and a pulse effect hiding in there.

In my experience the Multi-Plexer was useful for adding some lower frequencies and overtones to other synths placed in front of it. It gave a whole new dimension to the BBS synth.

The only thing I don't like about this pedal is that when you turn the power off it does not pass signal.
To get around this problem I used a true bypass looper to engage and disengage it.

I had a "synth pedalboard" going built with a handful of wacky pedals that I am selling now.
I decided to part it out only because I need the cash.
This pedal has been tested and is in good working condition.

Pedal has moderate wear, some scratches and scrapes in the faceplate and finish,
most notably a ding just beneath the Rate knob on the edge.

Includes original manual, and RCA Y to 1/4" cable (originally included), I guess this is for using the Multi-Plexer with turntables, MP3 players and the like? I never used or tested the cable, but it looks like it should work just fine.
Uses 2 9V batteries for operation. Has a power toggle to preserve battery power."
